Opinion

Memorandum and Order

WESLEY E. BROWN, Senior District Judge.

This matter came before the court on the defendants’ motions to exclude the testimony of plaintiffs’ experts and for summary judgment on all of plaintiffs’ claims. The court heard oral argument on October 13, 1998, and ruled orally on the motions at that time. This written memorandum will supplement the court’s oral ruling.

The plaintiffs are current or former employees of the United Methodist Church of Harper, Kansas. They allege that in July of 1995, employees of defendant Orkin were treating the church for termites when they negligently drilled through and injected termiticide into the heating and air conditioning duct work of the church. Approximately one year passed before this alleged contamination was discovered. The plaintiffs contend that they suffered physical and mental harm from exposure to chlorpyrifos, the active ingredient in the termiticide used by Orkin.

1. Defendant’s Motion to Exclude Plaintiffs’ Experts. Plaintiffs intend to offer the opinion testimony of two experts to show causation of their alleged injuries. One is Dr. Daniel Goldstein, a medical doctor board-certified in toxicology. The other is Dr. Dennis Helffenstein, a Ph.D. neuropsychologist. They will offer opinions that the plaintiffs suffered physical and psychological injuries caused by exposure to chlorpyrifos at the church. Defendant contends these experts are not qualified to express an opinion on the toxicology of chlorpyrifos and that their testimony does not meet the standard for admissibility of scientific testimony of Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993).

a. Qualifications. In summary, the expert qualifications cited by the plaintiffs are as follows. Dr. Daniel Goldstein, M.D., is currently an Associate Medical Director-Product Coordinator for the Monsanto Company. Prior to this position, he practiced medicine for ten years in Denver, Colorado, with a scope of practice including Clinical Toxicology, Occupational and Environmental Toxicology, Acute and Chronic Poisoning and Clinical Pharmacology. He is board certified by the American Board of Medical Toxicology, the American Board of Pediatries, the American Board of Clinical Pharmacology, and the Royal College of Physicians and Surgeons of Canada (Pediatrics). He is also board certified in medical toxicology under the current examinations conjointly offered by the American Board of Pediatrics, American Board of Emergency Medicine and the American Board of Preventive Medicine. In his clinical practice, he has diagnosed and treated hundreds of patients who have been exposed to toxic substances. Approximately one-third of his practice in the last ten years was in the area of forensic toxicology. He asserts that he is aware of the literature surrounding chlorpyrifos and organophosp-hates (the class of compounds to which chlor-pyrifos belongs), including medical literature dealing with organophosphate insecticides and their effect on the central nervous system. He has previous teaching experience in the area of organophosphates and their toxicological action and neuropathy as part of a course for the Colorado School of Mines. He has rewritten a large number of organo-phosphate documents for “Micromedics,” which is a primary reference of the vast majority of poison control centers.

Dr. Dennis Helffenstein is a Ph.D. who has practiced in neuropsychology for the past seventeen years. He has examined or treated over 300 patients who have been exposed *1302 to toxic substances. He has examined or treated 12-15 patients (including the plaintiffs) who have been exposed to organophosp-hate pesticides, 6 to 8 of whom (including the plaintiffs) have been exposed to chlorpyrifos. The majority of these cases have been individuals referred for treatment by their physicians. He states that he is aware of the literature dealing with neuropsychological injuries caused by exposure to organophosp-hate pesticides and has reviewed the literature on an individual basis to see how his patients fit the patterns discussed in the literature. He has done postgraduate work at toxicologic seminars that have included components on organophosphate pesticides.

The court has little trouble concluding that Dr. Goldstein has sufficient knowledge, education and experience to qualify as expert in the field of toxicology. The defendant appears to concede as much but argues that Dr. Goldstein does not have sufficient expertise with chlorpyrifos. The court rejects this argument as an overly constrictive view of the requirements of Rule 702. See Kannankeril v. Terminix Intern., Inc., 128 F.3d 802, 809 (3rd Cir.1997) (“We reject [defendant’s] suggestion that [the doctor] must be an expert in Dursban to provide expert testimony on the causation of [plaintiffs] injury.”).

As for Dr. Helffenstein, the court concludes that he has sufficient expertise in neuropsychology to express opinions falling within that specialty. This would include his opinion that the plaintiffs are suffering from cognitive and other deficits and his opinion as to the extent and duration of those problems. The court cannot find, however, that Dr. Helffenstein has sufficient expertise in the area of toxicology to offer an opinion that the cognitive and other deficits he found were caused by exposure to chlorpyrifos. The plaintiffs have not shown that Dr. Helffen-stein has sufficient training or experience to be thoroughly familiar with the methods of toxicology. He does not have an advanced degree in toxicology, pharmacology or epidemiology, and he is not certified as a specialist in these areas. He has done no original research with respect to organophosphates and his deposition testimony indicates a lack of familiarity with significant and relevant scientific literature on this topic. In sum, the court finds that the defendant’s motion to exclude Dr. Helffenstein’s opinion testimony as to causation should be granted.

The court notes the plaintiffs’ argument that the testimony of these two experts should be admitted under the “training and experience” exception to Daubert recognized by the Tenth Circuit. See Compton v. Subaru, 82 F.3d 1513 (10th Cir.1996). The court rejects this argument. 1 The court concludes that this exception does not apply to the facts of this case. As stated by the Eleventh Circuit, Daubert applies to the testimony of experts who rely on the application of scientific principles. Carmichael, 131 F.3d at 1435. The determination of whether a chemical agent caused a particular disease is clearly a matter of scientific inquiry. Moreover, the deposition testimony of the plaintiffs’ experts shows that they purported to rely on scientific methods in forming their opinions. Cf. Michigan Millers Mut. Ins. Corp. v. Benfield, 140 F.3d 915, 919 (11th Cir.1998). Plaintiffs cite no case applying the training and experience exception to an issue of chemical causation, and the court concludes that it would not apply in such a case.
