A comprehensive review of popular shopping guide lists, like the "Dirty Dozen" list, was commissioned by the Alliance for Food and Farming to examine the basis of the lists rankings, the methodology used to develop these lists and the scientific evidence linking pesticide residues and health effects.

  • The list is misleading to consumers in that it is based only upon exposure data while remaining silent about available information on the toxicity of pesticides present in the diet. As a result, the list does not provide a basis to assess risk. Merely detecting a residue does not provide an adequate scientific basis for judging whether or not there are potential health effects.
  • The U.S. EPA's current process for evaluating the potential risks of pesticides on food is rigorous and health-protective. The EPA's testing requirements for pesticides used on food are more extensive than for chemicals used in any other category, and include testing targeted specifically to assess the potential risks to fetuses, infants and children.
  • Given the widespread media attention devoted to the list, it is disconcerting that the authors have not shared their algorithm with the scientific community or the public, nor have they subjected it to an outside peer review — something the authors often demand of the regulatory agencies.
  • The currently available scientific data do not provide a convincing argument to conclude that there is a significant difference between the nutritional quality of organically grown food and food grown with conventional agricultural methods.

  • Dr. Karl RozmanKansas University Medical Center, Pharmacology, Toxicology & Therapeutics

    Dr. Rozman is a Professor of Pharmacology, Toxicology & Therapeutics at the Kansas University Medical Center. A member of many journal editorial boards, Dr. Rozman has published more than 30 original manuscripts on his research and has written many book chapters and review articles.

    • Diplomate of the American Board of Toxicology
    • Extensively studied chlorinated pesticides such as DDT, hexachlorbenzene, pentachlorophenol, dieldrin, heptachlor, chlordane and others
    • Current research aimed at understanding the mechanism of toxicity of chlorinated aromatic hydrocarbons (CAH) and related compounds, with three lines of research being pursued:
      1. Elucidation of the molecular mechanism(s) of action leading to CAH-induced enzyme inhibition
      2. Investigation of the subchronic and chronic toxicities of TCDD and its higher chlorinated homologues as well as other heterocyclic analogues such as chlorinated phenothiazines (CPT)
      3. Studying female reproductive toxicity of both CAH and CPT
