Under a 1988 amendment to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), the U.S. Environmental Protection Agency (EPA) regulates organophosphate pesticides Its focus was initially on registering pesticides for use on food crops. No pesticide can be sold in the United States before the EPA has reviewed the manufacturer's application for registration and determined that the use of the product will not present an unreasonable risk to the public or the environment. In 1996, with the passage of the Food Quality Protection Act, Congress required the EPA to reassess all existing pesticide tolerances with specific consideration for children. This resulted in a 10-year review process of the health and environmental effects of all pesticides, beginning with the organophosphates. As part of that process, in 1999 the EPA announced a ban the use of organophosphate pesticide methyl parathion and significant restrictions on the use of another OP, azinphos methyl, in what they called "kid's food". The review process was concluded in 2006 and eliminated or modified thousands of other uses of pesticides. Other legislative action has been taken to protect children from the risks of organophosphates.
