EPA Issues Emergency Suspension of Pesticide DCPA Due to Significant Health Risks

EPA Emergency Order on Pesticide Use

The U.S. Environmental Protection Agency (EPA) has issued an emergency order to suspend all uses of the pesticide dimethyl tetrachloroterephthalate (DCPA or Dacthal) due to significant health risks. This suspension marks the first time in nearly 40 years that the EPA has exercised such authority to prevent imminent hazard. DCPA, a widely used herbicide, has shown alarming long-term health impacts, especially among vulnerable populations like farmworkers and pregnant individuals.

Historically, DCPA has been in use in the United States since the late 1950s. Despite its prohibition in the European Union in 2009, the U.S. continued its usage until now.

Growing evidence, however, has revealed severe consequences stemming from prolonged exposure, propelling the EPA to take this urgent action.

Health and Environmental Risks

The herbicide DCPA poses serious health risks, particularly to farmworkers and pregnant women. It has been linked to thyroid damage, with the potential to cause long-term harm.

Moreover, studies have noted DCPA's propensity for causing thyroid tumors in animals, leading the EPA to classify it as a possible carcinogen in 1995. At the time, immediate action to ban the pesticide was not taken, but mounting concern now necessitates swift and decisive measures.

Pregnant individuals exposed to DCPA are at risk of harming the developing fetus, raising significant public health concerns.

Additionally, the environmental persistence of DCPA can lead to contamination of crops like kale, mustard greens, broccoli, and green onions, which are commonly treated with the herbicide. Therefore, the immediate suspension not only safeguards human health but also aims to protect the food supply from contamination.

Regulatory Measures and Future Actions

Following the EPA's requirement in 2013 for AMVAC, the sole manufacturer of DCPA in the U.S., to submit further studies on the herbicide's effects, compliance issues arose. AMVAC delayed submitting all necessary data until 2022, prompting a temporary suspension in August 2023, which was later lifted.

The current emergency order reinstates the suspension, emphasizing the severity of the risks involved and the need for diligent regulatory oversight.

Looking ahead, the EPA’s emergency order is a critical step towards the permanent cancellation of DCPA. The agency continues to assess the pesticide's risks and develop methodologies to mitigate its impact on human health and the environment. This ongoing process will likely involve stricter regulations and potential compensation for those affected by DCPA exposure.

Here's a thought to consider:

• The EPA's decisive actions are in response to compelling evidence of harm.
• Proactive measures protect vulnerable populations and our environment.
• Future regulations will likely prioritize human and environmental safety.
