Four US states have taken the country’s Environmental Protection Agency (EPA) to court, claiming the federal agency has not adequately curbed the nation’s pesticide use and is harming children’s health in the process.

The attorney generals of New York, New Jersey, Connecticut and Massachusetts say the EPA is not adhering to the 1996 Food Quality Protection Act, which dictates strict limits on pesticide use and stipulates that food commonly consumed by children must have pesticide levels ten times lower than those of adults.

The case focuses on a number of chemicals, used on popular children’s foods such as peanuts, apples, bananas and corn.
