Major Manufacturer of Chlorpyrifos Drops Out of Market, But EPA Continues to Allow Use

(Beyond Pesticides, February 12, 2020) Corteva, a company spun-off from DowDupont, will stop producing chlorpyrifos by the end of this year as a result of declining sales. Despite the move being in the interest of public health, the company is earning little praise from health advocates for what amounts to simply a shrewd financial decision. As news articles on the announcement have noted, Corteva will continue to support Environmental Protection Agency (EPA) registration of chlorpyrifos, which allows generic manufacturers to continue to sell this brain-damaging chemical.

“Other people are going to continue to profit from harming children,” said Marisa Ordonia, an attorney with the group EarthJustice to Canada’s National Observer. “It is big that such a major player is saying no, we’re not going to do this any more. It’s a great signal that people don’t want brain-damaging pesticides on their food. But we’re going to continue to keep fighting to make sure children and farmworkers are protected.”

At odds is the difference between halting production of chlorpyrifos and cancelling its EPA registration. While Corteva has the ability to voluntarily stop producing its own product, EPA registration permits other generic manufacturers to continue to producing the product. And, over the years, there would be nothing to stop Corteva from reintroducing “new” chlorpyrifos products back onto the market.  

Chlorpyrifos is an organophosphate class insecticide. Chemicals in this class are known to inhibit the proper nerve functioning by inactivating the enzyme acetylcholine esterase. Acute exposure to chlorpyrifos can result in numbness, tingling sensation, in-coordination, dizziness, vomiting, sweating, nausea, stomach cramps, headache, vision disturbances, muscle twitching, drowsiness, anxiety, slurred speech, depression, confusion and in extreme cases, respiratory arrest, unconsciousness, convulsions, and death. The chemical’s use in agriculture means that the general public is regularly exposed to smaller doses of the chemical in food.

The most concerning impacts of chlorpyrifos are seen in low income, fenceline, minority, and farmworker communities, where working or living near chlorpyrifos-sprayed fields can mean high rates of chronic exposure.

A study from the Columbia Children’s Center for Environmental Health (CCCEH) at Columbia University found that children exposed to high levels of chlorpyrifos had mental development delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorder problems at three years of age. Concentrations of chlorpyrifos in umbilical cord blood also corresponded to a decrease in the psychomotor development and a decrease in the mental development in 3 year olds.  A follow-up study in 2012 finds that children with high exposure levels of chlorpyrifos have changes to the brain, including enlargement of superior temporal, posterior middle temporal, and inferior postcentral gyri bilaterally, and enlarged superior frontal gyrus, gyrus rectus, cuneus, and precuneus along the mesial wall of the right hemisphere.

In 2016, EPA under the Trump administration reversed an impending ban on the chemical after, records reveal, then-EPA administrator Scott Pruitt met privately with Dow Chemical’s CEO. Since that time, EPA and environmental groups have battled out the chemical’s use in the courts (see this previous Daily News for a timeline). In July 2019, the agency announced officially that it would permit continued uses of chlorpyrifos indefinitely.

While EPA continues to fail to meet its namesake charge of protection of the environment, states and countries around the world taking meaningful action. Two years ago, Hawaii became the first state to take action through a phase-out that completely eliminates all use of the chemical by 2022. Soon after  California became the first state to eliminate use through the rulemaking process. In New York, a law passed by the state legislature implementing a ban prior to Hawaii’s was vetoed by Governor Cuomo (D) and shunted to a slower state rulemaking process. Meanwhile, the EU decided not to renew its registration for the chemical, permitting only a short grace period of 3 months for final storage, disposal and use.

The removal of Corteva (DowDupont) from the chlorpyrifos marketplace is indicative of a pattern within the current administration that puts profit at all cost above the health of the American people, and American children in particular, according to advocates. Decisions regarding public health should not be determined by the dictates of the marketplace, but by the sound science in states like NY, CA, and HI, the EU and other countries are following for the benefit of their residents. Help us send a message to EPA that science matters, and the agency must promote scientific integrity over corporate profits by signing your name today.
