EPA Issues Landmark Emergency Suspension of Pesticide DCPA Over Severe Health Risks
EPA Takes Decisive Action Against DCPA
The U.S. Environmental Protection Agency (EPA) has issued a landmark emergency order to halt the use of the pesticide dimethyl tetrachloroterephthalate (DCPA or Dacthal) due to substantial health hazards. This move marks the first emergency suspension of its kind in nearly 40 years, a testament to the serious risks posed by DCPA to public health, particularly for pregnant women and their unborn children.
Health risks identified by the EPA are grave; exposure to DCPA can lead to changes in fetal thyroid hormone levels. Such changes are linked to a myriad of adverse outcomes, including low birth weight, impaired brain development, decreased IQ, and impaired motor skills. Given these dangers, the EPA's order immediately prohibits the use, distribution, sale, and shipment of any pesticide product containing DCPA.
Impact on Agricultural Practices
The emergency order directly affects a range of products, namely Dacthal Flowable Herbicide, Dacthal W-75 Herbicide, and Technical Chlorthal Dimethyl, all registered by AMVAC. These products have been commonly utilized in agriculture settings to control weeds, especially in crops like broccoli, Brussels sprouts, cabbage, and onions.
To better understand the implications of this emergency order, the EPA collaborated with the U.S. Department of Agriculture (USDA). This collaboration aimed to gauge the extent of DCPA usage and to explore alternative pesticides that growers can employ without compromising crop yields.
Historical and Administrative Context
This decisive action has been years in the making. During the Biden-Harris Administration, efforts have been focused on addressing the specific risks posed by DCPA. One significant step was the issuance of a Data Call-In (DCI) in 2013 to AMVAC Chemical Corporation, requiring them to produce additional studies on DCPA's risks.
In April 2024, the EPA took a critical step by publicly warning about the serious health risks to unborn babies associated with DCPA exposure. This public warning was an important precursor to the current emergency order. Farmworker advocacy groups like Alianza Nacional de Campesinas have shown strong support for this emergency action, underscoring the significance of protecting farmworkers' health and reproductive rights.
Here's a thought to consider
The EPA's emergency suspension of DCPA is not just regulatory action; it’s a strong statement about prioritizing public health over agricultural convenience. This decision, supported by years of research and advocacy, highlights the importance of continual reassessment of pesticide safety. It drives home the need for growers and agricultural professionals to stay informed about the potential health impacts of pesticides they use.
