EPA questioned its ability to regulate pet products with pesticides, like Seresto, records show

• Newly released EPA records reveal internal debates over effective regulation of pet products
• EPA staff cited concern about one product in particular: Seresto, the popular flea and tick collar
• Some EPA staff were concerned enough that they discussed punting pet product regulation to the FDA
• The FDA is now helping the EPA in a review of Seresto, which has been the focus of many complaints

For years, U.S. Environmental Protection Agency officials have raised concerns that the agency’s process for determining the danger of the more than 400 pet flea and tick products it regulates is deeply flawed and has resulted in the use of pesticides that are potentially harmful to pets and their human owners.
