In February of this year, the EPA rejected all opposition to lifting the current maximum residue limit for chlorpyrifos in food poisoning, and all products containing chlorpyrifos will no longer be used for food purposes. As of October this year, the EPA has received 6 companies voluntarily canceling the registration of 16 chlorpyrifos products containing food purposes.

    There has been a turning point in the incident. Recently, the Eighth Circuit Court of Appeals of the United States overturned the Environmental Protection Agency's ban on chlorpyrifos, and agricultural groups agreed with the ruling, believing it to be scientifically reasonable. In this ruling, the court stated that the Environmental Protection Agency disregarded the scientific basis for scientists to ensure the safety of chlorpyrifos, thus revoking the ban and restoring its agricultural use.

    Illinois soybean growers, the American Soybean Association, the American Federation of Farm Bureaus, and the Sugar Beet Growers Association, among others, stated that this ruling conveys a message to the Environmental Protection Agency that the agency must base its rules on scientific evidence. In addition, these groups also hope to collaborate with the Environmental Protection Agency in the registration and review process of chlorpyrifos to ensure that the critical use of this tool is retained in the coming years.

    Chlorpyrifos are products used by farmers to protect crops from pests and other harmful organisms. Since 1965, chlorpyrifos has been widely used for both food and non food purposes.

    In 2007, anti pesticide groups applied to the Environmental Protection Agency to ban the use of chlorpyrifos, claiming that even small amounts of chlorpyrifos in food can damage the brains of infants and fetuses;

    In 2002, under pressure from the United States West Coast Court of Appeals for the Ninth Circuit, the Environmental Protection Agency ultimately banned the use of chlorpyrifos under the Federal Food, Drug, and Cosmetic Act in 2022;

    In February 2002, agricultural groups filed a lawsuit against the Environmental Protection Agency, demanding that farmers continue to be allowed to use the tool to protect crops. These groups emphasize that according to the Environmental Protection Agency's own records, professional scientists have discovered at least 11 efficient, low-risk agricultural uses of chlorpyrifos that can maintain safety.

    In the planting seasons of 2022 and 2023, many producers suffered losses due to the inability to use chlorpyrifos, and some farmers lost their only effective tool as a result, unable to protect crops from certain highly destructive pests. Therefore, growers urgently hope to restore the use of chlorpyrifos during the 2024 planting season.
