SECTION “R” (5) ORDER AND REASONS Before the Court is BP Exploration & Production, Inc., BP America Production Company, and BP p.l.c.’s (collectively the “BP parties”) motion to exclude the testimony of plaintiff’s general causation expert, Dr. Jerald Cook,1 and their motion for summary judgment.2 Plaintiff opposes both motions.3 The Court also considers plaintiff’s motion to admit the expert report of Dr. Cook as a sanction for defendants’ alleged spoliation,4 which defendants oppose.5 For the following reasons, the Court grants defendants’ motion to exclude the testimony of Dr. Cook. The Court denies plaintiff’s motion to admit Dr. Cook’s 1 2 3 4 5 R. Doc. 47.

Without Dr. Cook’s expert report, plaintiff cannot establish the general causation element of her claim at trial. Accordingly, the Court also grants defendants’ motion for summary judgment. I. BACKGROUND This case arises from plaintiff’s alleged exposure to toxic chemicals following the Deepwater Horizon oil spill in the Gulf of Mexico. Plaintiff alleges that she performed cleanup work after the Deepwater Horizon oil spill in 2010.6 Plaintiff asserts that, as a result of this work, she was exposed to crude oil or dispersants.7 She contends that this exposure has resulted in the following conditions: eye burning, watery eyes, dry eye syndrome, chronic interstitial lung disease, shortness of breath, pneumonia, cough, chest pain, body aches, dizziness, weakness, dehydration, chronic pain, headaches, depression, anxiety, rashes, bunion, lesions, hypersensitivity dermatitis, anemia, vomiting, diarrhea, gastroenteritis, dyspepsia, GERD, pneumonitis, asthma, chronic sinusitis, and chronic rhinitis.8 Plaintiff’s case was originally part of the multidistrict litigation (“MDL”) pending before Judge Carl J. Barbier. Her case was severed from the MDL as one of the “B3” cases for plaintiffs who either opted out of, or were excluded from, the 6 7 8 R. Doc. 1-1 at 5, 8. Id. R. Doc. 47-3 at 1-2. 2 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 3 of 34 Deepwater Horizon Medical Benefits Class Action Settlement Agreement.9 Plaintiff opted out of the settlement.10 After plaintiff’s case was severed, it was reallocated to this Court. Plaintiff asserts claims for general maritime negligence, negligence per se, and gross negligence against the defendants as a result of the oil spill and its cleanup.11 To demonstrate that exposure to crude oil, weathered oil, and dispersants can cause the symptoms plaintiff alleges in her complaint, she offers the testimony of Dr. Jerald Cook, an occupational and environmental physician.12 Dr. Cook is plaintiff’s sole expert offering an opinion on general causation.13 In his June 21, 2022 report, Dr. Cook utilizes a “general causation approach to determine if some of the frequently reported health complaints are indeed from the result of exposures sustained in performing [oil spill] cleanup work.”14 9 10 11 12 13 14 In re Oil Spill by Oil Rig “Deepwater Horizon” in the Gulf of Mex., on Apr. 20, 2010, No. MDL 2179, 2021 WL 6053613, at *2, 12 & n.12 (E.D. La. Apr. 1, 2021). R. Doc. 1-1 at 2. R. Doc. 30 ¶¶ 19-49. R. Doc. 47-4 (Cook Report). Plaintiff has also retained Dr. Rachel Jones, a certified industrial hygienist, to provide a report describing “the common, or shared, occupational exposures among worker[s]” who participated in the Deepwater Horizon response and cleanup. R. Doc. 48-5 at 4 (Jones Report). R. Doc. 47-4 at 16 (Cook Report). 3 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 4 of 34 The BP parties contend that Dr. Cook’s expert report should be excluded on the grounds that that it is unreliable and unhelpful.15 Defendants also move for summary judgment, asserting that if Dr. Cook’s general causation opinion is excluded, plaintiff is unable to carry her burden on causation.16 Plaintiff opposes both motions.17 Plaintiff contends that defendants’ failure to record quantitative exposure data during the oil spill response amounts to spoliation, and seeks the admission of Dr. Cook’s report as a sanction.18 Defendants oppose plaintiff’s motion.19 The Court considers the parties’ motions below. II. DEFENDANTS’ MOTION TO EXCLUDE DR. COOK’S TESTIMONY A. Legal Standard The district court has considerable discretion to admit or exclude expert testimony under Federal Rule of Evidence 702. See Gen. Elec. Co. v. Joiner, 522 U.S. 136, 138-39 (1997); Seatrax, Inc. v. Sonbeck Int’l, Inc., 200 F.3d 358, 371 (5th 15 16 17 18 19 R. Doc. 47. R. Doc. 48-1 at 1-2. R. Docs. 50 & 51. R. Doc. 49. R. Doc. 58. 4 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 5 of 34 Cir. 2000). Rule 702 provides that an expert witness “qualified . . . by knowledge, skill, experience, training, or education may testify” if: (a) the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or determine a fact in issue; (b) the testimony is based on sufficient facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the expert has reliably applied the principles and methods to the facts of the case. Fed. R. Evid. 702. In Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), the Supreme Court held that Rule 702 “requires the district court to act as a gatekeeper to ensure that ‘any and all scientific testimony or evidence admitted is not only relevant, but reliable.’” Metrejean v. REC Marine Logistics, LLC, No. 08-5049, 2009 WL 3062622, at *1 (E.D. La. Sept. 21, 2009) (quoting Daubert, 509 U.S. at 589). This gatekeeping function applies to all forms of expert testimony. See Kumho Tire Co. v. Carmichael, 526 U.S. 137, 147 (1999). The Court’s gatekeeping function consists of a two-part inquiry into reliability and relevance. First, the Court must determine whether the proffered expert testimony is reliable. The party offering the testimony bears the burden of establishing its reliability by a preponderance of the evidence. See Moore v. Ashland Chem. Inc., 151 F.3d 269, 276 (5th Cir. 1998). The reliability inquiry requires the Court to assess whether the expert’s reasoning and methodology 5 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 6 of 34 underlying the testimony are valid. See Daubert, 509 U.S. at 593. “[F]undamentally unsupported” opinions “offer[] no expert assistance to the [trier of fact]” and should be excluded. Guile v. United States, 422 F.3d 221, 227 (5th Cir. 2005). The Court may consider several nonexclusive factors in determining reliability, including: (1) whether the technique has been tested, (2) whether the technique has been subject to peer review and publication, (3) the technique’s potential error rate, (4) the existence and maintenance of standards controlling the technique’s operation, and (5) whether the technique is generally accepted in the relevant scientific community. Burleson v. Tex. Dep’t of Crim. Just., 393 F.3d 577, 584 (5th Cir. 2004). The Supreme Court has emphasized that these factors “do not constitute a ‘definitive checklist or test.’” Kumho, 526 U.S. at 150 (quoting Daubert, 509 U.S. at 593). Rather, courts “have considerable leeway in deciding in a particular case how to go about determining whether particular expert testimony is reliable.” Id. at 152. “The reliability analysis applies to all aspects of an expert’s testimony: the methodology, the facts underlying the expert’s opinion, the link between the facts and the conclusion, et alia.” Knight v. Kirby Inland Marine Inc., 482 F.3d 347, 355 (5th Cir. 2007) (internal quotation marks omitted). “Where the expert’s opinion is based on insufficient information, the analysis is unreliable.” Paz v. Brush Engineered Materials, Inc., 555 F.3d 383, 388 (5th Cir. 2009). Further, the 6 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 7 of 34 Supreme Court has explained that “nothing in either Daubert or the Federal Rules of Evidence requires a district court to admit opinion evidence that is connected to existing data only by the ipse dixit of the expert.” Joiner, 522 U.S. at 146. Rather, “[a] court may conclude that there is simply too great an analytical gap between the data and the opinion proffered.” Id. Second, the Court must determine whether the expert’s reasoning or methodology “fits” the facts of the case, and whether it will thereby assist the trier of fact to understand the evidence. In other words, it must determine whether it is relevant. See Daubert, 509 U.S. at 591. “Expert testimony which does not relate to any issue in the case is not relevant and, ergo, non-helpful.” Id. (quoting 3 J. Weinstein & M. Berger, Weinstein’s Evidence ¶ 702[02] (1988)). A district court’s gatekeeper function does not replace the traditional adversary system or the role of the jury within this system. See id. at 596. As noted in Daubert, “[v]igorous cross-examination, presentation of contrary evidence, and careful instruction on the burden of proof are the traditional and appropriate means of attacking shaky but admissible evidence.” Id. Thus, in determining the admissibility of expert testimony, the district court must accord the proper deference to “the jury’s role as the proper arbiter of disputes between conflicting opinions.” United States v. 14.38 Acres of Land, More or Less Situated in Leflore Cnty., Miss., 80 F.3d 1074, 1077 (5th Cir. 1996). 7 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 8 of 34 B. Discussion Plaintiff has the burden of “prov[ing] that the legal cause of [her] claimed injury or illness is exposure to oil or other chemicals used during the response.” In re Oil Spill by Oil Rig “Deepwater Horizon” in Gulf of Mex., on Apr. 20, 2010, No. MDL 2179, 2021 WL 6053613, at *11 (E.D. La. Apr. 1, 2021) (noting that B3 plaintiffs must prove that their alleged personal injuries were “due to exposure to oil or other chemicals used during the oil spill response”). The Fifth Circuit has developed a “two-step process in examining the admissibility of causation evidence in toxic tort cases.” Knight, 482 F.3d at 351. First, plaintiff must show general causation, which means that she must show that “a substance is capable of causing a particular injury or condition in the general population.” Id. Second, if the Court concludes that plaintiff has produced admissible evidence on general causation, it must then determine whether she has shown specific causation, in other words, that “a substance caused [that] particular [plaintiff’s] injury.” Id. If the Court finds that there is no admissible general causation evidence, there is “no need to consider” specific causation. Id. (citing Miller v. Pfizer, Inc., 356 F.3d 1326, 1329 (10th Cir. 2004)). At issue here is whether plaintiff has produced admissible general causation evidence. To prove that exposure to the chemicals in oil and dispersants can cause 8 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 9 of 34 the medical conditions plaintiff alleges, she offers the testimony of an environmental toxicologist, Dr. Cook. Dr. Cook asserts that his report is “based on the scientific methods used in the field of environmental toxicology.”20 More specifically, he states that his “causation analysis regarding health effects of oil spill exposures [] draw[s] on the process of evaluating epidemiology studies and the work from established expert groups similar to the Surgeon General’s Advisory Committee to make a more likely than not conclusion.”21 The Fifth Circuit has held that epidemiology provides the best evidence of causation in a toxic tort case. See Brock v. Merrell Dow Pharms., Inc., 874 F.2d 307, 311 (5th Cir. 1989). That is not to say that epidemiologic evidence “is a necessary element in all toxic tort cases,” but “it is certainly a very important element.” Id. at 313. As explained by the Fifth Circuit: Epidemiology attempts to define a relationship between a disease and a factor suspected of causing it . . . . To define that relationship, the epidemiologist examines the general population, comparing the incidence of the disease among those people exposed to the factor in question to those not exposed. The epidemiologist then uses statistical methods and reasoning to allow her to draw a biological inference between the factor being studied and the disease’s etiology. Id. at 311. 20 21 R. Doc. 47-4 at 8 (Cook Report). Id. at 20. 9 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 10 of 34 When, as here, a review of epidemiological studies forms the basis of an expert opinion, the essential first step requires the expert to identify an association. An association occurs when “two events (e.g., exposure to a chemical agent and development of disease) . . . occur more frequently together than one would expect by chance.” Fed. Judicial Ctr., Reference Manual on Scientific Evidence, 552 n.7 (3d ed. 2011) [hereinafter Reference Manual]. An association, by itself, is not equivalent to a finding of causation. Id. at 552. Unlike an association, “[c]ausation is used to describe the association between two events when one event is a necessary link in a chain of events that results in the effect.” Id. at 552 n.7. The Reference Manual indicates that “[a]ssessing whether an association is causal requires an understanding of the strengths and weaknesses of a study’s design and implementation, as well as a judgment about how the study’s findings fit with other scientific knowledge.” Id. at 553. Because “all studies have ‘flaws’ in the sense of limitations that add uncertainty about the proper interpretation of results,” the key questions in evaluating epidemiologic evidence “are the extent to which a study’s limitations compromise its findings and permit inferences about causation.” Id. Once an association is found, “researchers consider whether the association reflects a true cause-effect relationship,” that is, whether “an increase in the incidence of disease among the exposed subjects would not have occurred had they not been exposed to the agent.” Id. at 597-98. Alternative explanations, “such as 10 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 11 of 34 bias or confounding factors,” should first be considered. Id. at 598. If alternative explanations are not present, researchers apply the Bradford Hill criteria to evaluate whether an agent can be a cause of a disease. Id. at 597; Wagoner v. Exxon Mobil Corp., 813 F. Supp. 2d 771, 803 (E.D. La. 2011) (“[T]he set of criteria known as the Bradford Hill criteria has been widely acknowledged as providing an appropriate framework for assessing whether a causal relationship underlies a statistically significant association between an agent and a disease.”). The Bradford Hill factors include: (1) temporal relationship; (2) strength of the association; (3) dose-response relationship; (4) replication of findings; (5) biological plausibility; (6) consideration of alternative explanations; (7) cessation of exposure; (8) specificity of the association; and (9) consistency with other knowledge. Reference Manual at 600. These factors are not rigidly applied in a general causation analysis, but instead provide guidance for an expert “[d]rawing causal inferences after finding an association.” Id. Under Daubert, “courts must carefully analyze the studies on which experts rely for their opinions before admitting their testimony.” Knight, 482 F.3d at 355; Wagoner, 813 F. Supp. 2d at 799 (“Whether epidemiological studies support an expert’s opinion on the question of general causation in a toxic tort case is critical to determining the reliability of the opinion.”). Courts “may exclude expert testimony based on epidemiological studies where the studies are insufficient, 11 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 12 of 34 whether considered individually or collectively, to support the expert’s causation opinion.” Baker v. Chevron USA, Inc., 680 F. Supp. 2d 865, 875 (S.D. Ohio 2010) (citing Joiner, 522 U.S. at 156-57). But a court cannot exclude expert testimony just because it disagrees with the expert’s conclusions, although the Supreme Court has recognized that “conclusions and methodology are not entirely distinct from one another.” Joiner, 522 U.S. at 146. With the above standards in mind, the Court examines Dr. Cook’s general causation report. As noted by another section of this Court, “Cook issued an omnibus, non-case specific general causation expert report that has been used by many B3 plaintiffs.” Street v. BP Expl. & Prod. Inc., No. 17-3619, 2022 WL 1811144, at *2 (E.D. La. June 2, 2022). Dr. Cook’s report is divided into five chapters. The first chapter outlines Dr. Cook’s qualifications, which are not challenged in this case.22 The second chapter provides an overview of the Deepwater Horizon oil spill.23 The third chapter describes Dr. Cook’s methodology, the first step of which involved his “review and analy[sis]” of the “available scientific literature to determine the strength of an association between environmental exposure and a health effect.”24 After reviewing the literature, Dr. 22 23 24 Id. at 8. Id. at 9-15. Id. at 21. 12 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 13 of 34 Cook asserts that he selected the epidemiological studies cited in his causation analysis “based on the quality of the study and study design.”25 Chapter four of Dr. Cook’s report details prior studies on the health effects associated with oil spills.26 This section first provides “summaries of studies that evaluate health effects that may be associated with exposures from oil spill response and cleanup work” in past oil spills.27 It then discusses the findings and shortcomings of three studies on the Deepwater Horizon oil spill: (1) the National Institute for Occupational Safety and Health’s (“NIOSH”) Health Hazard Evaluations, (2) the Deepwater Horizon oil spill Coast Guard cohort study, and (3) the Gulf Long-Term Follow-Up study (“GuLF STUDY”).28 Chapter five presents Dr. Cook’s conclusions on general causation for four categories of health conditions: (1) respiratory conditions, (2) dermal conditions, (3) ocular conditions, and (4) cancers.29 Specifically, he reaches the following conclusions: Oil response and cleanup workers have reported acute symptoms of coughing; shortness of breath; wheezing; tightness in chest; and burning in nose, throat, and lungs. . . . Some individuals have prolonged effects from these exposures, and can develop chronic respiratory conditions . . . . These conditions include chronic rhinitis, chronic sinusitis, allergic rhinitis, chronic obstructive pulmonary disease (COPD), bronchitis, asthma or reactive airway disease . . . . General causation analysis indicates 25 26 27 28 29 Id. at 23. Id. at 62-102. Id. at 63. Id. at 66-102. Id. at 102. 13 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 14 of 34 that these acute and chronic respiratory conditions can occur in individuals exposed to crude oil, including weathered crude oil, during oil spill response and cleanup work.30 Chemical irritation would be the most common problem with workers, particularly for acute symptoms that occur during or shortly after exposure. These can be described as skin irritation, skin rash, or skin itching. Dermatitis may also occur following exposure to chemicals, such as crude oil, weathered crude oil, or dispersants. General causation analysis indicates that these acute and chronic [dermal] conditions can occur in individuals exposed to crude oil, including weathered crude oil, during oil spill response and cleanup work.31 Chemical irritation would be the most common problem with workers, particularly for acute symptoms . . . . These can be described as acute eye burning, acute eye irritation, and acute conjunctivitis. Chronic conditions following exposure can occur in a smaller subset of individuals who experience chronic inflammation affecting their eyes. The evidence available at this time does indicate that exposure to crude oil, including weathered crude oil, can result in acute and chronic eye symptoms. The medical problems most likely from these exposures are acute conjunctivitis, chronic conjunctivitis, and dry eye disease. General causation analysis indicates that these acute and chronic ocular conditions can occur in individuals exposed to crude oil, including weathered crude oil, during oil spill response and cleanup work.32 Based on Dr. Cook’s report, defendants argue that plaintiff is unable to prove general causation with relevant and reliable expert testimony. They contend that Dr. Cook’s general causation report is unreliable because he fails to: (1) identify the harmful dose of exposure of any particular chemical to which plaintiff was exposed 30 31 32 Id. at 120-121 (emphasis added). Id. at 126-127 (emphasis added). Id. at 133-134 (emphasis added). 14 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 15 of 34 that is necessary to cause the plaintiff’s conditions; (2) identify which chemicals can cause which conditions; (3) verify plaintiff’s diagnoses; and (4) follow the accepted methodology for analyzing epidemiology.33 Defendants also note that this Court and others in the district have excluded various versions of Dr. Cook’s report for similar reasons,34 including the version at issue in this case.35 It is undisputed that the only substantive change Dr. Cook made in version four is a revision to Section 3.4.1 of his report, which he updated to include tables stating 33 34 35 R. Doc. 47-1 at 7-20. This Court excluded the March 2022 version of Dr. Cook’s report in several cases on the grounds that his opinion was unreliable and unhelpful. See Dawkins v. BP Expl. & Prod., Inc., No. 17-3533, 2022 WL 2315846, at *8-9 (E.D. La. June 28, 2022); Coleman v. BP Expl. & Prod., Inc., No. 17-4158, 2022 WL 2314400, at *8-9 (E.D. La. June 28, 2022); Grant v. BP Expl. & Prod., Inc., No. 17-4334, 2022 WL 2467682, at *7-9 (E.D. La. July 6, 2022); Peairs v. BP Expl. & Prod., Inc., No. 17-3596, 2022 WL 2817852, at *7-11 (E.D. La. July 19, 2022). Judge Lance Africk excluded an earlier version of Dr. Cook’s report. See Novelozo v. BP Expl. & Prod., No. 13-1033, 2022 WL 1460103, at *7 (E.D. La. May 9, 2022). And Judge Barry Ashe excluded the March 2022 version of Dr. Cook’s report on the grounds that he failed “to identify the dose of the toxic chemicals necessary to cause any of the complained-of health effects.” Street, 2022 WL 1811144, at *6. Judge Susie Morgan excluded Dr. Cook’s March 2022 report on similar grounds. See Harrison v. BP Expl. & Prod. Inc., No. 17-4346, 2022 WL 2390733, at *7 (E.D. La. July 1, 2022) (“In sum, Cook did not identify the necessary dose of exposure for each of Plaintiff’s symptoms to manifest.”). Judge Barbier has excluded the same version of Dr. Cook’s report at issue here. Yarbrough v. BP Expl. & Prod., No. 17-4292, 2022 WL 3136982, at *1 (E.D. La. Aug. 5, 2022). 15 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 16 of 34 the minimal risk levels of a handful of chemicals found in crude oil and dispersants on certain systems of the human body.36 The Court first addresses defendants’ contention that Dr. Cook’s report is unreliable and cannot establish general causation because it does not identify a harmful level of exposure to a specific chemical to which plaintiff was exposed.37 The Court begins with this objection because “[s]cientific knowledge of the harmful level of exposure to a chemical” is considered “a minimum fact[] necessary to sustain the plaintiff’s burden in a toxic tort case.” Allen v. Pa. Eng’g Corp., 102 F.3d 194, 199 (5th Cir. 1996). Accordingly, if the Court finds that plaintiff cannot “prove, at [a] minimum, that exposure to a certain level of a certain substance for a certain period of time can cause a particular condition in the general population,” then the Court’s inquiry into general causation is complete. Williams v. BP Expl. & Prod., Inc., No. 18-9753, 2019 WL 6615504, at *8 (E.D. La. Dec. 5, 2019) (citing Knight, 482 F.3d at 351); Lee v. BP Expl. & Prod., Inc., No. 18-10381, 2020 WL 6106889, at *4 (E.D. La. Sept. 29, 2020) (“[D]istrict courts within the Fifth Circuit have likewise required toxic tort plaintiffs to define ‘the level of exposure necessary to produce effects’ in order to establish general causation.”); see also Seaman v. Seacor Marine L.L.C., 326 F. App’x 721, 726-27 (5th Cir. 2009) (per curiam) 36 37 R. Doc. 47-4 at 41-62 (Cook Report). R. Doc. 47-1 at 8-14. 16 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 17 of 34 (holding that “[w]ithout any facts that would establish the allegedly harmful level of exposure . . . Dr. Prellop’s opinion regarding diesel exhaust does not establish general causation”). Here, the Court finds that Dr. Cook’s failure to identify the level of exposure to a relevant chemical that can cause the conditions asserted in plaintiff’s complaint renders his opinion unreliable, unhelpful, and incapable of establishing general causation. Turning first to reliability, Dr. Cook makes clear in his report that a foundation of toxicology is that “dose determines the poison.”38 Because of this maxim, Dr. Cook explains that “[t]oxicologists study chemicals for the lowest levels that can cause adverse health effects . . . [which] requires sophisticated studies that can control the low dose while accurately measuring the effect of interest.”39 The AMA Guide also emphasizes the importance of determining the dose-response relationship. Specifically, the AMA Guide states that “the most critical phase of the hazard evaluation process” is to “determine whether the estimated dose was sufficient to explain observed clinical effects known to be associated with the agent in question.”40 It additionally cautions that “[i]f exposure-response and dose- 38 39 40 R. Doc. 47-4 at 32 (Cook Report). Id. R. Doc. 47-6 at 6-7. 17 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 18 of 34 response considerations are disregarded, then misinterpretations, misunderstandings, erroneous judgments, and inappropriate actions occur.”41 The closest Dr. Cook’s report comes to identifying a harmful level of exposure that can trigger specific health conditions is his consideration of the Bradford Hill factor of “dose-response.”42 But even in the sections of his report that are dedicated to the dose-response relationship and exposure, Dr. Cook still fails to identify a harmful dose of any chemical to which plaintiff was allegedly exposed. Further, he fails to even specify which constituent chemicals within “crude oil” and “weathered oil” he is purportedly analyzing for a dose-response relationship. Instead, in the “dose-response relationship” sections of his report, Dr. Cook simply cites studies from both the Deepwater Horizon oil spill, as well as previous oil spills, which generally found a positive association between respondents who reported higher levels of exposure to crude oil and the prevalence of various medical conditions.43 For example, Dr. Cook’s “dose-response relationship” analysis on rhinosinusitis states in full: Kim et al. (2013) showed a dose-response by assigning residents to zones based on their distance from the oil spill. The researchers found a dose-response effect in all reported health effects, including rhinitis. Rusiecki et al. (2022) also found a dose-response by statistical analysis, 41 42 43 Id. at 7. See, e.g., 47-4 at 107 (Cook Report). Id. at 107, 114, 124, 128 18 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 19 of 34 with the responders who had higher reported exposures having a higher incidence of chronic sinusitis.44 Notably, neither Dr. Cook, nor the two studies, specify a base level of exposure that is necessary to cause rhinosinusitis. In the Kim, et al., study, the respondents were “residents living in the Taean coastal area . . . [that] had potential exposures to the oil spill from the Hebei Spirit tanker.”45 Given the ambiguity in whether residents were even exposed to oil, the study does not specify what level of exposure it concludes is associated with rhinosinusitis. And in the Rusiecki, et al., 2022 study, whether a participant was a responder to the oil spill or not was used as a proxy for exposure, and “[o]ther exposure assessments were not used to classify the responders as exposed.”46 Again, any assessment of actual exposure, let alone the level of exposure to a particular chemical, was not available. These studies, both of which are “silent on the level of exposure . . . that would be significant,” do not assist Dr. Cook in “meeting [plaintiff]’s ‘minimal burden of establishing by ‘[s]cientific knowledge . . . the harmful level of exposure to a chemical.’” Seaman, 326 F. App’x at 727 (quoting Allen, 102 F.3d at 199). Dr. Cook’s report does acknowledge that one of the limitations of the studies he relies on is the “[l]imited availability of quantitative exposure measures,” given 44 45 46 Id. at 107. Id. at 65 (emphasis added). Id. at 79. 19 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 20 of 34 the “[l]ikely low [level of] individual exposures.”47 For example, he notes that the GuLF STUDY researchers represented that it was “difficult to obtain accurate and comprehensive exposure information on participants . . . because many of the assessments would have been made months after the workers were exposed,” and “many workers will have had multiple exposures during the oil spill, . . . such that single exposure measurements may not be sufficient to fully assess total exposure.”48 The report also mentions that the health hazard evaluations conducted by NIOSH “primarily utilized qualitative assessment techniques rather than the traditional industrial hygiene exposure assessment and quantitative measurement methods.”49 Although Dr. Cook notes these limitations, he provides no explanation about the “extent to which [these] limitations compromise [his] findings . . . about causation.” Reference Manual at 553. Given Dr. Cook’s failure to determine the relevant harmful level of exposure to chemicals to which plaintiff was exposed for plaintiff’s specific conditions, the Court finds that Dr. Cook lacks sufficient facts to provide a reliable opinion on general causation. See Moore v. Ashland Chem. Inc., 151 F.3d 269, 277-78 (5th Cir. 1998) (holding that the “district court was entitled to conclude” that an expert’s opinion was “inadequate under Daubert” when the expert “had no information on 47 48 49 Id. at 93. Id. Id. at 66. 20 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 21 of 34 the level of exposure necessary for a person to sustain the [relevant] injuries”); McGill v. BP Expl. & Prod., Inc., 830 F. App’x 430, 433 (5th Cir. 2020) (per curiam) (upholding the exclusion of an expert’s opinion that was “not based on sufficient facts” and relied on studies that failed to “provide conclusive findings on what exposure level of Corexit is hazardous to humans”). The Court also finds that Dr. Cook’s report is unhelpful to the factfinder for many of the same reasons. Rule 702 requires that an expert’s opinion must “help the trier of fact to understand the evidence or to determine a fact in issue.” Fed. R. Evid. 702(a). “To be ‘helpful’ under Rule 702, the evidence must possess validity when applied to the pertinent factual inquiry.” United States v. Posado, 57 F.3d 428, 433 (5th Cir. 1995). Courts should thus exclude testimony that “fail[s] to provide a ‘relevant’ link with the facts at issue.” Knight, 482 F.3d at 355. Here, the Court finds that Dr. Cook’s opinion is unhelpful because of his inability to link any specific chemical that plaintiff was allegedly exposed to, at the level at which she was exposed, to the health conditions that she purportedly experiences. Specifically, Dr. Cook’s conclusion that there is a cause-and-effect relationship between the respiratory, ocular, and dermal conditions he analyzed and “expos[ure] to crude oil, including weathered crude oil,” is unhelpful without 21 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 22 of 34 identifying the specific chemicals and exposure levels capable of causing specific conditions alleged by plaintiff.50 Although Dr. Cook admits that there are thousands of chemicals in crude oil, and that the chemical composition of weathered oil is highly variable, he makes no attempt to identify which chemicals within crude oil plaintiff was allegedly exposed to. Indeed, the majority of the studies he cites similarly do not identify which chemicals respondents were exposed to, and one study noted a concern about confounding variables, stating that some respondents likely had unknown “petrochemical and other exposures not due to their oil spill cleanup activities.”51 See Wagoner, 813 F. Supp. 2d at 802 (“It is true that in Joiner, the Supreme Court indicated that an expert opinion on general causation should rely on studies that examine the specific agent that is at issue.” (emphasis added) (citing Joiner, 522 U.S. at 145-46)). In providing a general causation determination, Dr. Cook had to assess whether “the types of chemicals [that plaintiff] w[as] exposed to can cause [her] particular injuries in the general population.” Knight, 482 F.3d at 355. Given that Dr. Cook’s report does not identify which specific chemicals plaintiff was exposed 50 51 R. Doc. 47-4 at 121 (Cook Report). Id. at 93 (Cook Report). 22 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 23 of 34 to, nor does it address many of the injuries plaintiff alleges,52 the Court finds his report is unhelpful to the factfinder. See Knight, 482 F.3d at 355 (upholding the district court’s exclusion of an expert because the expert relied on evidence that lacked “a ‘relevant’ link with the facts at issue”). In reaching its decision, the Court rejects plaintiff’s efforts to defend Dr. Cook’s failure to identify a harmful level of exposure to a specific chemical. Plaintiff asserts that Dr. Cook’s analysis relies on peer-reviewed scientific literature that is “the best, state of the art science on which to base causation opinions related to BP Oil Spill worker exposures.”53 Plaintiff attempts to bolster this position with an affidavit by Dr. Linda Birnbaum, the former director of the National Institute of Environmental Health and Safety, in which Dr. Birnbaum argues that it is not “plausible” to establish an oil-spill responder’s quantitative exposure to a particular chemical at a given level because of issues with data collection. As other sections of this court have noted, Dr. Birnbaum’s affidavit “neither cures nor explains the deficiencies in [Dr. Cook’s] report.” Griffin v. BP Expl. & Prod. Inc., 2023 WL 183894, at *5 (E.D. La. Jan. 13, 2023). “The question of an individual oil responder’s exposure level is relevant to specific causation, not general causation,” 52 53 For example, Cook’s report does not address chronic interstitial lung disease dizziness, “weakness,” dehydration, chronic pain, headaches, depression, anxiety, bunion, anemia, vomiting, diarrhea, gastroenteritis, dyspepsia, GERD, and pneumonitis. R. Doc. 50 at 1. 23 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 24 of 34 so “[t]he alleged impossibility of establishing a BP Oil Spill responder’s quantitative exposure to a given chemical at a given level does not affect Dr. Cook’s ability to consult the relevant scientific and medical literature on the harmful effects of oil to determine whether a relevant chemical has the capacity to cause the harm alleged by plaintiff in the general population.” Jenkins v. BP Expl. & Prod. Inc., 2023 WL 172044, at *2 (E.D. La. Jan. 12, 2023) (internal quotation marks omitted). Dr. Birnbaum’s representations about the difficulties scientists face quantifying individual responders’ exposures are thus “irrelevant to the issue of general causation in this case, which requires examination of the dose of exposure known to cause harm in the general population.”54 Id. Further, Dr. Cook states in his report that researchers associated with the Deepwater Horizon oil spill studies that he relies on have expressed concerns about the “accur[acy] and comprehensive[ness]” of respondents’ exposure responses.55 For example, the report notes that NIOSH investigators “disregarded the workers’ self-reports,” determining that the workers’ self-reported exposures had not been likely.56 Given the concerns about the accuracy of this model from 54 55 56 Further, Dr. Birnbaum was not timely disclosed as an expert. Her affidavit is thus procedurally improper. See Jenkins, 2023 WL 172044, at *1 n.6. R. Doc. 47-4 at 92 (Cook Report) (noting that “GuLF STUDY researchers also noted that it would be difficult to obtain accurate and comprehensive exposure information on participants in the GuLF STUDY”). Id. at 72. 24 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 25 of 34 both plaintiff’s expert as well as the investigators themselves, the Court does not find that, in this context, Dr. Cook’s conclusions are reliable. In sum, plaintiff, as the party offering the testimony of Dr. Cook, has failed to meet her burden of establishing the reliability and relevance of Dr. Cook’s report. Moore, 151 F.3d at 276. Given that Dr. Cook’s report is unreliable and fails to provide the “minimal facts necessary” to establish general causation in this case, see Allen, 102 F.3d at 199, the Court grants defendants’ motion to exclude Dr. Cook’s testimony. See Seaman, 326 F. App’x at 727-28 (upholding the district court’s exclusion of an expert’s testimony that did “not come close to establishing either general or specific causation” and “provide[d] no clue regarding what would be a harmful level of Ferox exposure”). III. PLAINTIFF’S SPOLIATION MOTION A. Legal Standard The spoliation of evidence doctrine concerns the intentional destruction of evidence. Menges v. Cliffs Drilling Co., 2000 WL 765082, at *1 (E.D. La. June 12, 2000) (citing Vodusek v. Bayliner Marine Corp., 71 F.3d 148, 156 (4th Cir. 1995); Schmid v. Milwaukee Elec. Tool Corp., 13 F.3d 76, 78 (3d Cir.1994)). If a party intentionally destroys evidence, the trial court may exercise its discretion to impose sanctions on the responsible party. Id. The sanctions may include an 25 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 26 of 34 instruction to the jury to infer that “that the evidence would have been unfavorable to the party responsible for its destruction.” Kronisch v. United States, 150 F.3d 112, 126 (2d Cir.1998). See, e.g., Vodusek, 71 F.3d at 155; Schmid, 13 F.3d at 78; Glover v. BIC Corp., 6 F.3d 1318, 1329 (9th Cir. 1993); Nation–Wide Check Corp. v. Forest Hills Distribs., 692 F.2d 214, 217–18 (1st Cir. 1982); In re Hopson Marine Transp., Inc., 168 F.R.D. 560, 567 (E.D. La. 1996). This adverse inference rule “derives from the common sense notion that a party’s destruction of evidence which it has reason to believe may be used against it in litigation suggests that the evidence was harmful to the party responsible for its destruction.” Kronisch, 150 F.3d at 126. Accordingly, to restore the prejudiced party, an adverse inference “plac[es] the risk of an erroneous judgment on the party that wrongfully created the risk.” Id. (quoting Nation–Wide Check, 692 F.2d at 218). Before a court may consider imposing sanctions, however, “the party having control over the evidence must have had an obligation to preserve it at the time it was destroyed.” Menges, 2000 WL 765082, at *3. Such a duty “arises when the party has notice that the evidence is relevant to litigation.” Id. Once a court concludes that a party was obliged to preserve the evidence, it must then consider whether the evidence was intentionally destroyed and the likely contents of that evidence. Id. The Fifth Circuit requires the party who seeks sanctions to show that the party who allegedly spoiled the 26 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 27 of 34 evidence acted in “bad faith.” King v. Illinois Cent. R.R., 337 F.3d 550, 556 (5th Cir. 2003); see also Anderson v. Prod. Mgmt. Corp., No. 98–2234, 2000 WL 492095, at *3 (E.D. La. Apr. 25, 2000) (collecting authorities). Negligence is not enough to support the imposition of sanctions for spoliation, “for it does not sustain an inference of consciousness of a weak case.” Vick v. Texas Employment Comm’n, 514 F.2d 734, 737 (5th Cir. 1975). Accordingly, a party seeking sanctions is not entitled to an adverse inference unless that party can show that its adversary intentionally and in bad faith disposed of the evidence. B. Discussion Plaintiff contends that Dr. Cook’s report should be admitted as a sanction for defendant’s alleged spoliation. Plaintiff contends that this sanction is appropriate because “BP’s decision not to record quantitative exposure data during the BP Oil Spill response has deprived plaintiff of data which would quantitatively establish [her] exposure.”57 A party seeking an adverse-inference instruction generally must show that “(1) the party with control over the evidence had an obligation to preserve it at the time it was destroyed; (2) the evidence was destroyed with a culpable state of mind; 57 R. Doc. 49-1 at 1. 27 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 28 of 34 and (3) the destroyed evidence was ‘relevant’ to the party’s claim or defense such that a reasonable trier of fact could find that it would support that claim or defense.” Coastal Bridge Co., LLC v. Heatec, Inc., 833 F. App’x 565, 574 (5th Cir. 2020) (citing Port of S. La. v. Tri-Parish Indus., 927 F. Supp. 2d 332, 346 (E.D. La. 2013); Herster v. Bd. of Supervisors of Louisiana State Univ., 887 F.3d 177, 190 (5th Cir. 2018)). Plaintiff’s spoliation motion suffers a number of deficiencies. First, plaintiff’s contention that BP’s failure to conduct monitoring amounts to spoliation is based on the faulty premise that BP was obligated to develop evidence in anticipation of litigation. Fairley v. BP Expl. & Prod. Inc., No. 17-3988, 2022 WL 16731817, at *3 (E.D. La. Nov. 3, 2022). Spoliation is the intentional destruction of evidence or failure to preserve evidence in one’s possession. Menges v. Cliffs Drilling Co., 2000 WL 765082, at *1 (E.D. La. June 12, 2000) (citing Vodusek v. Bayliner Marine Corp., 71 F.3d 148, 156 (4th Cir. 1995); Schmid v. Milwaukee Elec. Tool Corp., 13 F.3d at 78 (Here, plaintiff has identified no evidence that defendants destroyed, and courts have made clear that, as a general matter, a “failure to collect evidence [is] not a failure to preserve evidence, and as such, [is] not spoliation.” See, e.g., Fairley, 2022 WL 16731817, at *3 (E.D. La. Nov. 3, 2022); De Los Santos v. Kroger Tex., LP, 2015 WL 3504878, at *6 n.4 (N.D. Tex. June 3, 2015) (holding that “the duty to preserve evidence does not include the duty to 28 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 29 of 34 create evidence.”); United States v. Greco, 734 F.3d 441, 447 (6th Cir. 2013) (“A failure to collect evidence that may or may not have been available for collection is very different from the intentional destruction of evidence that constitutes spoliation.”). Plaintiff asserts that BP was aware of risks to clean-up workers’ heath, knew that biological monitoring was useful, and received suggestions to conduct monitoring, but “suggestions and proposals do not equate to an affirmative duty.” Fairley, 2022 WL 16731817, at *4 (E.D. La. Nov. 3, 2022) (denying plaintiff’s spoliation motion premised on BP’s alleged failure to collect data related to the oil spill cleanup). As other sections of this court have observed, plaintiff identifies “no source (statute, rule, or other dictate) imposing a duty on BP to conduct such monitoring and, by suggesting that monitoring was necessary to create evidence of exposure, . . . concedes that no such evidence ever existed for BP to preserve.” Jenkins, 2023 WL 172044, at *1. Further, the remedy plaintiff seeks—admission of Dr. Cook’s expert opinion despite its numerous deficiencies—is unwarranted. Dr. Cook’s report is flawed in ways unrelated to BP’s decision not to conduct monitoring. Indeed, “a general causation opinion is not dependent upon data from the incident at issue, but does require an explanation of whether the exposure to a particular chemical is capable generally of causing certain health issues for the general population.” Fairley, 29 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 30 of 34 2022 WL 16731817, at *4. Dr. Cook’s failure to link any specific chemicals to the conditions allegedly suffered by plaintiff prevents the admission of Cook’s opinion. The Court thus declines plaintiff’s invitation to admit Dr. Cook’s report as a sanction “despite its failure to meet the requirements of Fed. R. Evid. 702.” Francisco v. BP Expl. & Prod. Inc., No. 17-3212, Doc. 70 (E.D. La. Feb. 16, 2023). Accordingly, plaintiff’s spoliation motion is denied. IV. DEFENDANTS’ MOTION FOR SUMMARY JUDGMENT A. Legal Standard Summary judgment is warranted when “the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a); see also Celotex Corp. v. Catrett, 477 U.S. 317, 322-23 (1986); Little v. Liquid Air Corp., 37 F.3d 1069, 1075 (5th Cir. 1994) (en banc) (per curiam). “When assessing whether a dispute to any material fact exists, [the Court] consider[s] all of the evidence in the record but refrain[s] from making credibility determinations or weighing the evidence.” Delta & Pine Land Co. v. Nationwide Agribusiness Ins., 530 F.3d 395, 398-99 (5th Cir. 2008). All reasonable inferences are drawn in favor of the nonmoving party, but “unsupported allegations or affidavits setting forth ‘ultimate or conclusory facts and conclusions of law’ are insufficient to either support or defeat a motion for 30 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 31 of 34 summary judgment.” Galindo v. Precision Am. Corp., 754 F.2d 1212, 1216 (5th Cir. 1985) (quoting 10A Charles Alan Wright & Arthur R. Miller, Federal Practice and Procedure § 2738 (2d ed. 1983)); see also Little, 37 F.3d at 1075. “No genuine dispute of fact exists if the record taken as a whole could not lead a rational trier of fact to find for the nonmoving party.” EEOC v. Simbaki, Ltd., 767 F.3d 475, 481 (5th Cir. 2014). If the dispositive issue is one on which the moving party will bear the burden of proof at trial, the moving party “must come forward with evidence which would ‘entitle it to a directed verdict if the evidence went uncontroverted at trial.’” Int’l Shortstop, Inc. v. Rally’s, Inc., 939 F.2d 1257, 1264-65 (5th Cir. 1991) (quoting Golden Rule Ins. v. Lease, 755 F. Supp. 948, 951 (D. Colo. 1991)). “[T]he nonmoving party can defeat the motion” by either countering with evidence sufficient to demonstrate the “existence of a genuine dispute of material fact,” or by “showing that the moving party’s evidence is so sheer that it may not persuade the reasonable fact-finder to return a verdict in favor of the moving party.” Id. at 1265. If the dispositive issue is one on which the nonmoving party will bear the burden of proof at trial, the moving party may satisfy its burden by pointing out that the evidence in the record is insufficient with respect to an essential element of the nonmoving party’s claim. See Celotex, 477 U.S. at 325. The burden then 31 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 32 of 34 shifts to the nonmoving party, who must, by submitting or referring to evidence, set out specific facts showing that a genuine issue exists. See id. at 324. The nonmovant may not rest upon the pleadings, but must identify specific facts that establish a genuine issue for resolution. See, e.g., id.; Little, 37 F.3d at 1075 (“Rule 56 ‘mandates the entry of summary judgment, after adequate time for discovery and upon motion, against a party who fails to make a showing sufficient to establish the existence of an element essential to that party’s case, and on which that party will bear the burden of proof at trial.’” (quoting Celotex, 477 U.S. at 322)). B. Discussion In their motion for summary judgment, defendants contend that they are entitled to summary judgment because plaintiff cannot establish either general or specific causation.58 As discussed in Section II.B, supra, expert testimony is required to establish general causation in toxic-tort cases like this one. See McGill, 830 F. App’x at 433-34 (affirming summary judgment where plaintiff lacked admissible expert testimony on general causation); see also Macon v. BP Expl. & Prod. Inc., No. 17-3548, 2022 WL 1811135, at *7 (E.D. La. June 2, 2022) (dismissing plaintiff’s claims “[b]ecause expert testimony is required on [general 58 R. Doc. 48. 32 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 33 of 34 causation]”). Here, the Court has excluded testimony from plaintiff’s only expert offering an opinion on general causation. In his opposition to defendants’ motion, plaintiff notes that other sections of this court have denied summary judgment in cases in which B3 plaintiffs have brought claims premised on transient or temporary symptoms.59 See Stephens v. BP Expl. Prod. Inc., 2022 WL 1642136 (E.D. La. May 24, 2022); Wallace v. BP Expl. & Prod. Inc., 2022 WL 1642166 (E.D. La. May 24, 2022); Turner v. BP Expl. & Prod. Inc., 2022 WL 1642142 (E.D. La. May 24, 2022); Walker v. BP Expl. & Prod. Inc., No. 17-3012, R. Doc. 69 (E.D. La. June 15, 2022). But those summary judgment motions were premised on a lack of expert testimony on specific causation. The defendants did not challenge the admissibility of Dr. Cook’s general causation opinions in those cases. Here, the Court need not “sort [plaintiff’s] claimed symptoms into those requiring expert testimony on specific causation and those that do not because [plaintiff] cannot provide the required expert testimony on general causation once Cook’s report is excluded.” Johns v. BP Expl. & Prod. Inc., 2022 WL 1811088, at *3 n.44 (E.D. La. June 2, 2022). Given that plaintiff cannot prove a necessary element of her claims against defendants, her claims must be dismissed. See Williams, 2019 WL 6615504, at *11 (“When a plaintiff has no expert testimony to prove his medical diagnosis or 59 R. Doc. 50 at 5-7. 33 Case 2:17-cv-03295-SSV-MBN Document 60 Filed 02/28/23 Page 34 of 34 causation at trial, the plaintiff’s suit may be dismissed at the summary judgment stage.”); see also McGill, 830 F. App’x at 434 (upholding the district court’s grant of summary judgment given that the plaintiff did “not put forward any nonspeculative evidence that Corexit and oil exposure cause the types of illnesses he suffer[ed] from”). Accordingly, the Court grants defendants’ motion for summary judgment. V. CONCLUSION For the foregoing reasons, the Court GRANTS the BP parties’ motion to exclude the testimony of Dr. Cook. The Court DENIES plaintiff’s motion to admit Dr. Cook’s report as a sanction for defendants’ alleged spoliation. The Court also GRANTS the BP parties’ motion for summary judgment. Plaintiff’s claims are DISMISSED WITH PREJUDICE. 28th day of February, 2023. New Orleans, Louisiana, this _____ _____________________ SARAH S. VANCE UNITED STATES DISTRICT JUDGE 34
