EPA responds to Illinois Rep concerning Hayes’ atrazine based frog gonad assertions

Illinois State Representative, Dave Winters, who heard Dr. Hayes’ testimony  last February regarding frog gonads sent a letter to USEPA asking if it were true that they had reviewed all Dr. Hayes’ data as Dr. Hayes testified.  USEPA replied to Representative Winters this week.

The response states:

“. . . I regret that the EPA science staff in the office of Pesticide Program’s EFED (Environmental Fate and Effects Division) could not properly account for the sample sizes and study design reportedly used by the Berkeley researchers. As a result, we were unable to complete any independent analysis to support the study’s conclusions.”

“. .  .no reliable determination of cause-effect or concentration-response relationship could be established between atrazine and reported effects in amphibians.”

“EPA presented its review to a FIFRA (Federal Insecticide, Fungicide Rodenticide Act) SAP (Scientific Advisory Panel) and concluded that it was reasonable to reject the hypothesis formulated in 2003 that atrazine exposure can affect gonadal development. The Agency also determined that there was no compelling reason to pursue additional testing with regard to the potential effects of atrazine on amphibian gonadal development.”

    The EU banned Atrazine in Europe because of its links to breast and prostate cancer. This chemical now a prominently found chemical in our fresh water. The US allows the use of many chemicals that the rest of the developed world has banned and/or outlawed. I’d rather lean towards a safer policy for the public and vote with the majority no this than put people in danger.


  2. The source in which you are getting atrazine info is inaccurate. Atrazine is not banned in the EU.

    “It is frequently asserted that atrazine has been banned in the EU. This is an incorrect interpretation of the EC decision. Atrazine has not been assessed and de-registered because of a human health or environmental concern. It is not on any EU ‘banned list” and could theoretically be reregistered in the EU should the product registrant provide all the required data. Terbuthylazine, a herbicide very closely related to atrazine is registered in the EU.” (http://www.apvma.gov.au/news_media/chemicals/atrazine.php#amphibians)

    No one cares more about the safety of agricultural pesticides than the farmers who use them on their crop and soils—where their own children play. Over 6,000 tests and studies over the past 50 years prove that atrazine is a safe and beneficial product. For more information on atrazine, visit: http://www.agsense.org.
