NZ Issues Red Alert Over US-Banned Weedkiller Linked to Health Risks
The Environmental Protection Authority (EPA) has issued an urgent warning advising people to stop using a commonly used weedkiller due to serious health concerns, particularly its potential effects on unborn children.
The alert comes after the EPA initiated an investigation into the herbicide Dacthal, also known as DCPA, following its removal from store shelves in the United States last week. Dacthal is widely used worldwide for controlling annual grasses and broadleaf weeds in vegetable cultivation.
Dr. Shaun Presow, the EPA’s manager of hazardous substances reassessments, highlighted the urgent nature of the situation. “We have issued this alert due to significant concerns about the potential health risks associated with the herbicide,” he said. “We strongly urge anyone using products containing chlorthal-dimethyl to stop immediately and seek safer alternatives.”
For those unable to avoid using products with chlorthal-dimethyl, the EPA advises taking stringent precautions to minimize exposure, especially for pregnant women or those who could become pregnant. These precautions include restricting access to treated areas and ensuring no one is present during the application process.
The U.S. Environmental Protection Agency (USEPA) has identified a risk of thyroid hormone disruptions in unborn children of pregnant bystanders, women applying the herbicide, and individuals entering fields treated with chlorthal-dimethyl. Such hormonal changes can lead to low birth weight and irreversible, lifelong health issues, including impaired brain development and motor skills.
In response to these findings, the EPA has established a working group to evaluate the herbicide’s use in the region and to implement swift actions to protect public health. “While this evaluation is ongoing, we have issued a red alert to raise public awareness of the potential dangers,” Dr. Presow added.
The EPA is also consulting with stakeholders who may be affected by any potential new regulations regarding the use of DCPA herbicides to ensure the safety and well-being of the community.
