*570 MEMORANDUM
This is a diversity action in which plaintiffs, the Villari family, allege that defendant pest control corporation, Terminix Inc. (“Terminix”), contaminated their home with termiticides. The defendants have submitted several motions in limine relating to the admissibility of certain evidence. This Memorandum addresses each of these motions.
I. Motion to Exclude Certain Animal Experiments from Evidence on the Issue of the Human Carcinogenicity of Aldrin, Dieldrin, Chlordane & Heptachlor
In the first motion, the defendant seeks to exclude from evidence certain studies, including animal studies, involving defendant’s termiticides. Among the studies the defendant seeks to exclude are a recent report by the United States Environmental Protection Agency, entitled “Chlordane, Heptachlor, Aldrin and Dieldrin, Technical Support Document,” and a report of the National Academy of Sciences, entitled “An Assessment of the Health Risks of Seven Pesticides Used for Termite Control.” The plaintiffs intend to introduce the studies to show that defendant’s termiticides are probable human carcinogens. The plaintiffs plan to call two expert witnesses whose testimony at trial will be based, among other things, on these reports.
The defendant argues that the studies constitute “novel scientific evidence” and therefore are subject to the test of admissibility set forth in
United States v. Downing,
A. Defendant’s Claim that the Studies are Novel Scientific Evidence
In a detailed memorandum, the defendant challenges the validity of using animal studies to predict the carcinogenicity of pesticides in humans. In the defendant’s view, such studies have disputed value in isolating the effects of individual substances, see Defendant’s Memorandum in Support of Motion to Exclude Certain Animal Experiments from Evidence, at 26-31 & Appendix “A” (chronicling the difficulties of carcinogenic research with mice), in distinguishing between cancerous and non-cancerous changes in animal subjects, see id., at 31-33, and in relating their findings to human carcinogenicity, see id., at 34-63. Because there is wide disagreement concerning the reliability of particular findings of these studies, the defendant concludes, the evidence must be regarded as novel scientific evidence, and the techniques on which it is based should be reviewed for their soundness.
In making this argument, the defendant confuses disagreements about particular results with disagreements about the processes that generate those results. Only the latter set of disagreements concerns the admissibility of scientific evidence; the former relates to the weight such evidence should be accorded. In
Downing,
the court declared that “[ejvidence that derives from principles and techniques of uncontroverted validity is, of course, readily admissible.”
It is worthy of mention that counsel for the defendant does not make any reference in his seventy-eight page Memorandum to Judge Stern’s letter opinion in Boltuch v. Terminix, Civil Action No. 84-3235 (D.N.J. April 16, 1986), which squarely addressed the issue of whether the studies in this case constitute novel scientific evidence. Judge Stern ruled that “both the NAS report and the animal studies derive from well-established scientific principles and techniques, and neither is based on ‘novel form of scientific expertise’ within the meaning of United States v. Downing.” Id. at 11. Given that lead counsel for Terminix in the case at bar was one of Terminix’s attorneys in Boltuch, it is hard to see how the non-reference to Boltuch could have been inadvertent.
B. Defendant’s Claim that the Studies Should Be Excluded Under Fed.R. Evid. 703 or Fed.R.Evid. 403
(1) The Admissibility of the Studies Under Fed.R.Evid. 703
The defendant argues that Fed.R. Evid. 703 bars the testimony of plaintiffs’ experts on the animal studies. Fed.R.Evid. 703 provides:
The facts or data in the particular case upon which an expert bases an opinion or inference may be those perceived by or made known to the expert at or before the hearing. If of a type reasonably relied upon by experts in the particular field in forming opinions or inferences upon the subject, the facts or data need not be admissible in evidence.
The Third Circuit has taken a liberal approach to the introduction of expert testimony by allowing experts to base their opinions on data that is reasonably relied upon by other experts in the field. There is no separate requirement that the court itself find the data to be trustworthy.
See, e.g., In re Japanese Electronic Products Antitrust Litigation,
Both parties have submitted documentation concerning the reliability of the plaintiffs’ studies. Defendant’s experts cast doubt on the findings of the studies, suggesting that the carcinogenicity of chemicals in animals provides weak inferential support for the dangerousness of those chemicals to humans. In contrast, the plaintiffs refer to numerous U.S. agencies and scientific organizations that routinely rely on animal studies in assessing risks to humans. I find, by the weight of the plaintiffs’ submissions, that a substantial portion of the scientific community relies oh animal studies of this type in assessing health risks to humans. That some members of the scientific community hold differing views is not enough to exclude evidence under Fed.R.Evid. 703. 1
Because I am persuaded that the studies are routinely relied upon by members of the relevant scientific community, I will not exclude the studies on the basis of Fed.R. Evid. 703.
(2) The Admissibility of the Studies Under Fed.R.Evid. 403
The defendant urges that the animal studies, even if found not to be novel scientific evidence, should be excluded because their probative value is outweighed by their potential to overwhelm, mislead, and confuse the jury. The support defendant offers for this position is unpersuasive.
First, the defendant cites
In re: “Agent Orange”Product Liability Litigation,
*572
As to prejudice, the defendant argues that this court should adopt the reasoning set forth by two other district courts on the admissibility of animal studies.
See
Defendant’s Memorandum, at 73-74 (citing
In re “Agent Orange” Product Liability Litigation,
In the Agent Orange litigation, Judge Weinstein found the animal experiment studies to be potentially misleading in large part because the plaintiffs’ own experts conceded that the studies were of dubious value in determining the effects of Agent Orange on humans.
See
Because Fed.R.Evid. 403 provides- for the exclusion of relevant evidence, it “should be invoked very sparingly” and only when the probative value of the evidence is substantially outweighed by the potential for undue harm.
See, e.g., Hendrix v. Raybestos-Manhattan, Inc.,
Accordingly, the defendant’s first motion will be denied.
II. Motion to Exclude the Testimony & Reports of G. John Digregorio, M.D., Ph.D. and Wendell W. Kilgore, Ph.D.
The plaintiffs intend to call two experts, G. John Digregorio and Wendell W. Kilgore, to offer testimony relating, among other things, to the toxicity of the termiticides to which the plaintiffs were exposed, and to the plaintiffs’ risk of future illness as a result of their exposure. Their testimony will rely in part on the animal studies discussed above.
The first basis defendant offers in support of this Motion — that the opinions of plaintiffs’ experts are not based upon data reasonably relied upon by other experts in their field — is resolved by the ruling on the motion above.
The additional case support defendant presents for this motion does not alter my view that these animal experiment studies are reasonably and routinely relied upon by other scientists. The defendant cites
Felgenhauer v. Texaco, Inc.,
Slip Op. No. 85-3671 (Dec. 1, 1987) [available on WEST-LAW,
The defendant also refers to the decision in
Viterbo v. Dow Chemical Co.,
The defendant’s insistence that three Circuit courts have “unequivocably [sic] held ... animal studies ... unreliable in the scientific community as a predictor of effects in man” is simply unwarranted. Defendant’s Memorandum in Support of Motion to Exclude Testimony and Reports, at 15. As pointed out above, the question of whether any
particular
animal study provides the kind of basis on which an expert in the field may reasonably rely requires an examination of the context in which the study is made. Thus, defendant’s reference to
Gulf South Insulation v. U.S. Consumer Product Safety Comm’n,
The defendant’s second argument to exclude testimony is that Pennsylvania law bars admission of speculative testimony concerning increased risk of future injury. Although defendant concedes that a doctor may offer a prognosis of a person already injured, Defendant’s Memorandum, at 20 (citing
Boyle v. Pennsylvania R.R. Co.,
Finally, the defendant contends that Dr. Kilgore may not testify as to the health of the plaintiffs because he is not a medical doctor. This claim is unsupported. While it is true that an expert must demonstrate special competence to present expert testimony,
see, e.g., Aloe Coal Co. v. Clark Equip.,
Accordingly, the defendant’s second motion will be denied.
III. Motion to Preclude the Evidence of Terminix’s Discontinuance of the Use of Aldrin, Chlordane and Heptachlor and the Evidence that these Termiticides Are No Longer Distributed in the United States
The defendant asserts that its voluntary choice to discontinue its use of certain *574 termiticides constitutes a subsequent remedial measure, evidence of which is inadmissible under Fed.R.Evid. 407. The rule states:
When, after an event, measures are taken which, if taken previously, would have made the event less likely to occur, evidence of the subsequent measures is not admissible to prove negligence or culpable conduct in connection with the event. This rule does not require the exclusion of evidence of subsequent measures when offered for another purpose, such as proving ownership, control, or feasibility of precautionary measures, if controverted, or impeachment.
A. Evidence of Terminix’s Discontinuance of Use
The plaintiffs offer a number of arguments for allowing the introduction of evidence relating to the defendant’s discontinuance of use. First, plaintiffs contend that the discontinuance was not voluntary, and hence the purposes underlying the exclusion of a defendant’s remedial measures are not implicated. Second, plaintiffs argue that their anticipated uses of the evidence are not restricted by Fed.R.Evid. 407, because they do not plan to use the evidence to prove defendant’s negligence. Finally, the plaintiffs urge that the motion should not be granted until it is clear that the evidence cannot be introduced for a permissible purpose under Fed.R.Evid. 407, such as to prove feasibility or to impeach defendant’s witnesses. These arguments are not persuasive.
The strong policy justification underlying Fed.R.Evid. 407 — the concern that permitting the introduction of evidence of remedial measures to show past negligence will deter efforts to remove potential hazards— suggests that any exception to the rule should be crafted carefully so as to not deter possible corrective efforts.
See, e.g., Werner v. Upjohn Co., Inc.,
In this case, the defendant discontinued its use of termiticides containing chlordane and heptachlor at the same time that the Environmental Protection Agency was negotiating with Velsicol Chemical Corporation (“Velsicol”), a primary manufacturer of these termiticides, to discontinue their sale. See Environmental News, attached to Plaintiffs’ Memorandum as Exhibit “G”, at 3-4 (describing EPA’s review of termiticide uses over the past decade). The defendant was under no legal obligation to discontinue its use of chlordane and heptachlor. Moreover, although the relevant regulatory agencies were contemplating the promulgation of stricter standards, they provided explicitly for the legal use of the termiticides at issue at the time of the defendant’s decision. See Defendant’s Reply Memorandum in Support of Motion to Exclude Evidence of Discontinuance of Use, at 2. Under such circumstances, allowing the plaintiff to introduce evidence of the defendant’s discontinuance of use would run counter to the purposes of Fed. R.Evid. 407.
Plaintiffs also argue that Fed.R.Evid. 407 is inapplicable because they do not anticipate introducing evidence of defendant’s discontinuance of use to prove negligence. Rather, they plan to introduce the evidence to prove the dangerousness of defendant’s termiticides. Terminix’s discontinuance of use, however, is not necessarily probative of the dangerousness of the product, and may well be excludable as irrelevant under Fed.R.Evid. 401.
See
C. Wright & K. Graham,
Federal Practice and Procedure: Evidence
§ 5282, at 95-96
*575
(1978) (discussing as one rationale underlying Fed.R.Evid. 407 the likelihood that a defendant’s later conduct is not probative of the safety of his earlier conduct);
cf. Dine v. Western Exterminating Co.,
Slip Op., Civil Action No. 86-1857 (D.D.C. March, 1988) [available on WESTLAW,
More importantly, the plaintiffs’ assertion that the evidence can be used to show the dangerousness of the product without also implicating negligence on the part of the defendant is dubious. Negligence is certainly related to the dangerousness of the product with which one is dealing. The standard of care appropriate to the disposal of ordinary garbage unquestionably differs from the standard appropriate to the disposal of toxic waste. To the extent plaintiffs prove the dangerousness of the product through evidence of defendant’s discontinuance of use, they also support their claim of defendant’s negligence. This unavoidable inference suggests that the plaintiffs are in fact using the defendant’s subsequent actions to prove negligence, exactly the purpose proscribed by Fed.R.Evid. 407.
Finally, plaintiffs argue that this court should not rule on this motion until it is clear whether the evidence can be used to show feasibility or to impeach defendant’s witnesses, two permissible uses for evidence otherwise excludable under Fed.R. Evid. 407. If plaintiffs at some point demonstrate that the evidence can be offered for a purpose consistent with Fed.R.Evid. 407, they may seek to introduce it at that time. At the present time, I rule only that the evidence constitutes a subsequent remedial effort by Terminix, and that it may not be introduced to support plaintiffs’ claim of the dangerousness of the termiticides.
B. Evidence that the Termiticides are No Longer Distributed in the United States
The defendants argue that evidence that the termiticides are no longer distributed in the United States should be excluded either as irrelevant under Fed.R.Evid. 401 or excessively prejudicial under Fed.R. Evid. 403. 2
Much of the evidence relating to the withdrawal of termiticides from the United States market has been excluded in other litigation.
See Dine v. Western Exterminating Co.,
Slip Op., Civil Action No. 86-1857 (D.D.C. March 18, 1988) (holding that evidence of Velsicol’s agreement with the EPA to cancel certain uses of chlordane and heptachlor was not probative of the carcinogenicity of these termiticides);
Rabb v. Orkin Exterminating Co.,
*576 Accordingly, the defendant’s Motion to Preclude the Evidence of Terminix’s Discontinuance of the Use of Aldrin, Chlordane, and Heptachlor and the Evidence that these Termiticides Are No Longer Distributed in the United States will be granted.
IV. Motion to Exclude Evidence on Failure to Warn
In their complaint, plaintiffs assert that the defendant should be held strictly liable under § 402A of the Restatement (Second) of Torts for its alleged failure to warn of the dangers associated with its termiticides. In this motion, the defendant seeks to exclude evidence relating to its alleged failure to warn. The defendant offers two arguments. First, the defendant claims that it cannot be deemed a seller or distributor of a product in plaintiffs’ § 402A strict liability action because the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S. C. § 136 et. seq. (1982) (“FIFRA”), provides that a certified applicator who does not deliver any unapplied pesticides should not be viewed as a seller or distributor under the Act. The defendant maintains that Congress intended in this section to insulate certified applicators from strict liability under § 402A. The defendant’s second argument is that FIFRA preempts any state law tort claim based on defendant’s alleged failure to warn.
A. The Definition of “Seller” Under FI-FRA
In ruling on defendant’s Motion for Summary Judgment,
Villari v. Terminix Int’l Inc.,
Section 136(e)(1) provides that
[A certified applicator is] any individual who is certified under section 136b of this title as authorized to use or supervise the use of any pesticide which is classified for restricted use. Any applicator who holds or applies registered pesticides, or use dilutions of registered pesticides consistent with subsection (ee) of this section, only to provide a service of controlling pests without delivering any unapplied pesticide to any person so served is not deemed to be a seller or distributor of pesticides under this sub-chapter.
The defendant contends that if Terminix is viewed as a non-seller under FIFRA, it cannot be viewed as a seller for the purposes of plaintiffs’ § 402A action. Accordingly, defendant argues, the plaintiffs’ strict liability action must fail, because liability under § 402A attaches only to those who have sold a product.
See
Defendant’s Memorandum, at 8 (citing
Kohr v. Johns-Manville Corp.,
Although § 136(e)(1) does express Congress’s intent to treat certain individuals who apply pesticides as non-sellers, it is apparent from other passages in § 136 that Terminix is not an individual within the meaning of the Act. Hence, FIFRA does not preclude plaintiffs’ strict products liability action based on Terminix’s alleged failure to warn.
The Act refers in various sections to both “persons” and “individuals.” The drafters’ decision to use one of the terms rather than the other, so as to indicate whether a requirement extends to a single individual or to a business, is deliberate throughout the statute. For example, § 136b, which governs the certification procedure, provides in pertinent part that
In any State in which the Administrator conducts a certification program, the Administrator may require any person engaging in the commercial application sale, offering for sale, holding for sale, or distribution of any pesticide one or *577 more uses of which have been classified for restricted use to maintain such records
... as the Administrator may by regulation prescribe____ Such standards shall provide that to be certified, an individual must be determined to be competent with respect to the use and handling of pesticides____ (emphasis added)
In addition, “person” is defined in § 136 of the Act as “any individual, partnership, association, corporation, or any organized group of persons whether incorporated or not.” Given this definition of “person,” Congress seems to have intended that the term “individual,” as used in § 136(e)(1), should retain its ordinary meaning. Thus, § 136(e)(1) reflects an intent to protect “individual[s],” and not entities such as Terminix, from liability as “seller[s] or distributors] of pesticides.”
Moreover, as the plaintiffs point out in their brief, Terminix’s role in this case was far greater than that of a licensed applicator of termiticides. Terminix served as the seller, distributor, and applicator of the termiticides used in the plaintiffs’ home.
Thus, neither the language of § 136(e)(1) nor the law of Pennsylvania prevents Terminix from being viewed as a seller for the purposes of plaintiffs’ § 402A strict liability action.
B. Defendant’s Claim that Plaintiffs’ State Law Tort Action for Failure to Warn is Preempted by FIFRA
The defendant contends that § 136v reveals Congress’s intention to preempt state law tort actions against pesticide companies based on inadequate warnings. Section 136v allows for state regulation of the sale or use of federally registered pesticides but proscribes state imposition of labeling or packaging requirements that add to or differ from those required by the Act. The section reads, in pertinent part:
(a) A State may regulate the sale or use of any federally registered pesticide or device in the State, but only if and to the extent the regulation does not permit any sale or use prohibited by this subchapter.
(b) Such State shall not impose or continue in effect any requirements for labeling or packaging in addition to or different from those required under this sub-chapter.
Congress may preempt state law through either express language or implication.
See, e.g., Cipollone v. Liggett Group, Inc.,
It is clear from § 136v that FIFRA contemplates a regulatory role for states in the area of pesticides. The only question is whether plaintiffs’ claim based on defendant’s alleged failure to warn falls within the range of permissible state regulation or conflicts with FIFRA’s prohibition of state labeling and packaging requirements.
The defendant argues that this court should follow the reasoning of
Fitzgerald v. Mallinckrodt, Inc.,
The plaintiffs do not assert that their injuries were the result of the defendant’s failure to comply with federal regulations regarding the labeling and packaging of defendant’s pesticides. Rather, their claim is that the defendant had an obligation, under state common law, to ensure that an appropriate warning reached not only the employees who handled the pesticides, but
*578
also the plaintiffs themselves, as the ultimate consumers of the pesticides.
See
Plaintiffs’ Response to Defendant’s Motion, at 8 (citing
Davis v. Wyeth Laboratories, Inc.,
Recognition of this “failure-to-warn” claim does not conflict with FIFRA’s prohibition of state labeling or packaging requirements because the defendant’s liability is unrelated to the manner in which the product is labeled or packaged. Under plaintiffs’ theory, liability attaches as a result of defendant’s failure to relay the warning that FIFRA requires sellers to affix to their product. 3
In addition, the plaintiffs’ contention that their failure-to-warn claim does not conflict with FIFRA is strengthened by the fact that their claim encompasses events subsequent to the defendant’s application of termiticides in their home. The plaintiffs maintain that the defendant had a duty to inform them of any health risks posed by the termiticide spill in their basement. This claim in no way involves the federally-mandated labeling and packaging requirements of FIFRA.
Finally, the obvious purpose underlying FIFRA’s prohibition of state labeling and packaging requirements — that non-uniform requirements by states would burden interstate trade of pesticides — is not undermined by the plaintiffs’ failure-to-warn claim. Success by the plaintiffs would provide no incentive to the defendant or any other seller of termiticides to alter its labeling or packaging. Rather, such success should, as its only effect, encourage compliance with state regulations concerning the sale and use of pesticides, a result wholly consistent with § 136 of FIFRA.
Accordingly, defendant’s Motion to Exclude Evidence on Failure to Warn will be denied.
ORDER
For the reasons stated in the accompanying Memorandum, it is ORDERED that:
1. Defendant’s Motion to Exclude Certain Animal Experiments from Evidence on the Issue of the Human Carcinogenicity of Aldrin, Dieldrin, Chlordane & Heptachlor is DENIED;
2. Defendant’s Motion to Exclude the Testimony & Reports of G. John Digregorio, M.D., Ph.D. and Wendell W. Kilgore, Ph.D. is DENIED;
3. Defendant’s Motion to Preclude the Evidence of Terminix’s Discontinuance of the Use of Aldrin, Chlordane and Heptachlor and the Evidence that these Termiticides are No Longer Distributed in the United States is GRANTED;
4. Defendant’s Motion to Exclude Evidence on Failure to Warn is DENIED.
Notes
. If defendants are able to demonstrate at trial, through cross-examination or other means, that an overriding segment of the scientific community repudiates the value of the studies, it would be appropriate to seek their exclusion at that time.
. The defendant seems to concede, correctly, that remedial efforts by non-parties are not ex-cludable via Fed.R.Evid. 407 unless the non-party has a sufficient interest in the litigation such that the introduction of evidence of its remedial efforts may deter its undertaking those efforts. For a discussion of the admissibility of third-party remedial efforts, see Wright & Graham, supra, § 5248, at 112-13.
. The defendant argues that because the product used in plaintiffs' home was a diluted version of the termiticide regulated under FIFRA, no warning need have been given to the plaintiffs. This argument, however, goes to the merits of the plaintiffs’ claim and not to whether that claim is preempted by FIFRA.
