GAO Report Questions Adequacy of EPA’s Conditional Pesticide Registration System

(Beyond Pesticides, September 11, 2013) In a report released Monday, the Government Accountability Office (GAO) finds that the U.S. Environmental Protection Agency (EPA)’s use and oversight of conditional registrations is lacking and unreliable. Conditional registration allows pesticides onto the consumer market without all the required data to assess the chemical’s safety. This has created many […]
