Link Between Dacthal and Birth Defects
In an August 2024 press release announcing Dacthal’s cancellation, the EPA indicates that unborn babies whose pregnant mothers are exposed to the pesticide, in some cases unknowingly, could experience changes to fetal thyroid hormone levels, which in turn can result in a range of developmental issues and long-term health problems.
According to the EPA, these changes in fetal thyroid hormone levels have been linked to a variety of adverse outcomes in exposed babies, including low birth weight, impaired brain development, decreased IQ, and impaired motor skills. In some cases, these effects may be irreversible, potentially leading to lifelong challenges for affected children and their families.
The EPA’s findings are particularly concerning given the widespread use of Dacthal and the potential for exposure among pregnant women. The agency estimates that pregnant women who are exposed to DCPA may have exposure levels that are four to 20 times higher than what is considered safe for unborn babies.
This heightened risk is likely due to the herbicide’s persistence in the environment, as well as the potential for exposure through various pathways, such as direct contact with treated fields, spray drift, or contaminated food and water sources.
