Two groups have gone to court seeking a total ban on the pesticide chlorpyrifos. Residential use of the pesticide, under the brand name Dursban, was banned in 2001. However, it is widely used in agriculture under the name Lorsban. Chlorpyrifos is toxic to humans and can cause muscle spasms, dizziness, seizures, vomiting, diarrhea and paralysis, according to the lawsuit.
The complaint was filed in New York state by the Natural Resources Defense Council and Pesticide Action Network North America. The two groups are seeking to force the Environmental Protection Agency (EPA) to act on a three-year-old petition to remove the product from the market. EarthJustice filed the lawsuit on behalf of the two groups.
â€œThis dangerous pesticide has no place in our fields, near our children, or on our food,â€ Earthjustice attorney Kevin Regan said in a statement. â€œWeâ€™re asking a court to rule so that EPA will finish the job and ban this poison.â€
A number of other countries have already outlawed use of chlorpyrifos, including South Africa in May. However, it is still widely used in the US as an insecticide on corn, grapes, oranges, almonds and other crops, on golf courses and for pest control in urban areas.
In June 2000, after a lengthy review, the EPA reached an agreement with Dow Chemical to ban most home and garden uses of Dursban, citing health risks to children. The agency also required that Dursban use be phased out in areas where children would be most likely to be exposed â€“ schools, daycare centers, parks and recreation areas, stores and malls.
Unfortunately, under the phase out, all stocks of the pesticide were permitted to remain on store shelves until they were used up. As a result, people continued buying Dursban products, often ignorant of their health risks.
Dow Chemical has faced allegations that it withheld information about Dursbanâ€™s risks, and marketed it as a safe pesticide, despite knowing the opposite was true. In 1995, for instance, Dow was fined $732,000 for not sending the EPA its reports on 249 Dursban poisoning incidents.
In 2003, Dow agreed to pay $2 million â€“ the largest penalty ever in a pesticide case â€“ to the state of New York. The state had filed suit against Dow for repeatedly violating a 1994 agreement that prohibited advertising that touted the safety of its pesticide products. However, an investigation found that almost immediately after the company entered into the agreement, it once again began to make misleading safety claims in its print, video and internet advertising.
