In a historic move, the U.S. Environmental Protection Agency (EPA) has taken emergency action to suspend the use of a pesticide known as dimethyl tetrachloroterephthalate (DCPA) or Dacthal. This marks the first time in 40 years that the EPA has implemented such measures due to the irreversible damage caused to babies when exposed to the pesticide in utero.

The decision comes after extensive research linking Dacthal to serious health risks for newborns. Studies have found that exposure to this pesticide during pregnancy can result in low birth weight, decreased IQ, impaired brain development, and hindered motor skills later in life. Michal Freedhoff, the assistant administrator for the Office of Chemical Safety and Pollution Prevention, emphasized the urgency of the situation, stating, "DCPA is so dangerous that it needs to be removed from the market immediately."

DCPA is primarily used to control weeds in agricultural and non-agricultural settings, with crops such as broccoli, Brussels sprouts, cabbage, and onions being heavily reliant on its effectiveness. The concerning aspect is that pregnant women may not even be aware of their exposure to this harmful pesticide.

The EPA's decision was prompted by the failure of Dacthal's manufacturer, AMVAC Chemical Corporation, to provide sufficient data on the health risks associated with DCPA. This lack of information raised concerns about the safety of those exposed, particularly pregnant women. A 2023 assessment by the EPA confirmed the link between DCPA and health risks, stating that even when individuals using personal protective equipment were exposed, pregnant women may have experienced levels of DCPA up to 20 times higher than what is deemed safe for fetuses.

Although AMVAC proposed some changes following the EPA's assessment, the agency determined that these modifications did not adequately address the serious health risks faced by individuals working with or around Dacthal.

The EPA's decision has been welcomed by advocacy groups, including Alianza Nacional de Campesinas. Mily Treviño Sauceda, the executive director of the organization, expressed her satisfaction with the EPA's action, stating, "We know intimately the harm that pesticides, including (DCPA), can inflict on our bodies and communities." She further emphasized the importance of listening to farmworkers, protecting reproductive health, and safeguarding families.

With this landmark decision, the EPA aims to prioritize the health and safety of unborn babies and prevent any further harm caused by Dacthal exposure. The suspension of this pesticide's use serves as a critical step towards protecting the well-being of pregnant women and their families, while emphasizing the need for comprehensive assessment and regulation of harmful chemicals in the agricultural industry.
