Chlorpyrifos Pesticide Challenge

A farm field.

Farmworkers and their families, who are predominantly low-income and majority Latino, bear the brunt of poisonings from pesticides and pesticide drift.

What’s at Stake

Widespread agricultural use of chlorpyrifos means that people continue to be exposed through contaminated foods, drinking water, and pesticide blowing off of farmland and into neighboring areas.

Early childhood exposure to chlorpyrifos can cause reduced IQ, developmental delays, loss of working memory, and other neurological damage.

Overview

In 2001, the U.S. Environmental Protection Agency banned residential use of chlorpyrifos because of the harm to children exposed in the home. Chlorpyrifos continues to be heavily used on fruit and nut orchards, soybeans, and corn, with an estimated 5 million pounds applied in the U.S. annually. This widespread agricultural use means that people continue to be exposed through contaminated foods, drinking water, and pesticide blowing off of farmland and into neighboring areas.

In 2007, Pesticide Action Network North America and Natural Resources Defense Council, represented by Earthjustice, filed a petition asking EPA to ban all uses of chlorpyrifos to afford the same protection to rural children exposed through pesticide drift. PANNA and NRDC also asked EPA to protect children from reduced IQ, developmental delays, loss of working memory, and other neurological damage cased by early childhood exposures. Young children are particularly vulnerable to the pesticide because their bodies and brains are still developing, and chemicals that interfere with the nervous system during development may cause long-term or permanent damage.

When EPA failed to act, the groups went to court to force EPA to act. Each time, EPA promised to take action, but it continually missed its self-imposed deadlines.

Chlorpyrifos Rehearing Ruling

The 9th Circuit Court of Appeals rules health and labor organizations will have to argue, again, in court that chlorpyrifos, a brain-damaging pesticide, must be banned from all food use. The decision comes four months after Andrew Wheeler’s Environmental Protection Agency asked the court to rehear the case.
