Who Is Most at Risk from Dacthal Exposure?
The people most at risk from Dacthal exposure are agricultural workers who handled or applied the herbicide, farm laborers who worked in treated fields, and pregnant women and their unborn babies who lived or worked near where it was sprayed. Because Dacthal, also called DCPA, could linger in the soil for weeks, exposure often happened quietly, without anyone realizing it.
For decades, the herbicide Dacthal was sprayed across American farmland, and countless people were exposed to Dacthal without ever knowing it — including many who may now have grounds for a Gainesville toxic tort claim. In 2024, federal regulators took the rare step of pulling it off the market because of serious risks to pregnant women and their unborn babies. Now, workers and families across Florida are asking a fair question: Was I exposed, and what does that mean for my health? A Dacthal (DCPA) lawyer can help you find out.
We put this guide together to help you understand who was most likely exposed to Dacthal, also known as DCPA, how that exposure happened, and what your options are if you or your child was harmed. At Bagen Law Accident Injury Lawyers, P.A. we have spent more than 40 years standing up for injured people and grieving families throughout North Central Florida.
The hardest part of this story is that so much of the harm was invisible. A worker could finish a normal day in the field, or a mother could spend a quiet afternoon at home, and neither would sense that anything was wrong.
Key Takeaways about Who Was at Risk for Dacthal Exposure
- Dacthal, also known as DCPA, is a weed-killing herbicide that federal regulators banned in 2024 over serious health risks.
- Agricultural workers who mixed, applied, or worked around treated crops faced the highest risk of Dacthal exposure.
- Pregnant women and their unborn babies were the group of greatest concern, with risks tied to fetal thyroid and brain development.
- People living near sprayed fields, and families using nearby water sources, could also have been exposed.
- Because Dacthal could remain in fields for weeks, many people were exposed without ever realizing it.
What Is Dacthal, and Why Was It Banned?
Dacthal is the brand name for a weed-killing chemical called DCPA, and the U.S. Environmental Protection Agency banned it in 2024 because it posed serious, sometimes irreversible risks to unborn babies. It was one of the most drastic pesticide actions the agency had taken in nearly 40 years.
Dacthal is a pre-emergent herbicide, which means it was applied to stop weeds before they sprouted. It was used mainly on vegetable crops such as broccoli, Brussels sprouts, cabbage, and onions, and it had been part of American agriculture since the late 1950s. A single company manufactured it for the U.S. market.
In August 2024, the EPA issued an emergency order suspending all uses of Dacthal, the first emergency suspension of a pesticide in almost 40 years. Two months later, in October 2024, the agency finalized the cancellation of every Dacthal product, which made it illegal to sell or even use leftover supplies.
What stands out is how long the warning signs were there. The product had already been pulled from the European market years earlier, and U.S. regulators had raised concerns about its effect on the thyroid for a long time before finally acting. The reason for such fast and unusual action in the end came down to one group of people: pregnant women and the children they were carrying.
Who Was Exposed to Dacthal in the Workplace?
Agricultural workers faced the greatest workplace risk of Dacthal exposure, especially those who mixed, loaded, or sprayed the herbicide and those who entered fields after it was applied. According to the EPA, even workers wearing protective equipment could still be exposed at unsafe levels.
Farm work involves close, repeated contact with the crops and the soil where Dacthal was used. The people at highest risk on the job included:
- Applicators who mixed and sprayed the herbicide directly
- Field workers who planted, weeded, or harvested treated crops
- Laborers who re-entered fields soon after an application
What made this especially concerning is that the chemical did not break down quickly, so walking back into a field that looked perfectly safe could still cause exposure.
The EPA found that Dacthal could stay at unsafe levels in a treated field for 25 days or more, far longer than the short re-entry window printed on the product label. For workers who spent long days in the fields season after season, that meant contact could build up over weeks, months, and years.
Florida is one of the nation’s largest producers of fresh vegetables, and crops like cabbage and leafy greens are grown across the state, including in the farming communities around North Central Florida. Many local workers may have spent years around the very crops where Dacthal was commonly used.
Nursery and Landscape Workers
Farmworkers were not the only ones at risk. Dacthal was also used on some ornamental plants grown in nurseries and on certain turf, such as golf courses and athletic fields, so people who tended those spaces could have been exposed as well. If your work brought you into regular contact with treated plants or ground, it is worth including in your health history.
How Were Families and Communities Exposed to Dacthal?
Families and neighbors were often exposed to Dacthal without ever touching it, mainly by living near treated fields or by drinking water from areas where the herbicide had been used. Pregnant women who simply lived close to farmland were among those the EPA worried about most.
When Dacthal was sprayed, it did not always stay put. Wind could carry it to nearby homes, yards, and schools, a process called spray drift. People who breathed that air or touched dusty surfaces could be exposed and never know it.
Water was another path. The EPA has pointed to potential risks from drinking water that contains Dacthal residues in areas near where it was applied in the past. Rural families who depend on private wells may be especially affected.
Interestingly, the agency did not find the same level of risk from eating foods grown with Dacthal. Still, for people living and raising children in farming areas, exposure through the air, soil, and water remained a real and lasting concern. Even small children playing outside could carry residue indoors on their hands, shoes, and clothing.
The Health Risks of Dacthal Exposure
The most serious health risk of Dacthal exposure was to unborn babies, whose developing thyroid glands could be disrupted by the chemical. The EPA linked this disruption to low birth weight, impaired brain development, lower IQ, and reduced motor skills, and it warned that some of these effects may be permanent.
The thyroid is a small gland that produces hormones essential for healthy growth, and those hormones are especially important during pregnancy. When a pregnant woman is exposed to Dacthal, the chemical can change fetal thyroid hormone levels at the very time a baby’s brain and body are forming.
What alarmed regulators was the sheer size of the risk. The EPA estimated that some pregnant women handling Dacthal products could face exposures four to 20 times higher than the level the agency considered safe for a developing baby.
For a family, this can be heartbreaking, because a child’s lifelong health challenge may trace back to an exposure the mother never felt or saw. Some of the changes cannot be undone, which is why regulators treated the danger as an emergency rather than something to study for a few more years.
Signs You or a Loved One May Have Been Exposed to Dacthal
You may have been exposed to Dacthal if you worked on or near farms that grew vegetables like broccoli, cabbage, or onions, or if you lived close to those fields, especially in the years before the 2024 ban. There is no single test that proves past exposure, so your personal history matters most.
Because exposure so often happened quietly, identifying it means looking back at where you lived and worked. A few questions can help:
- Did you work as a farm laborer, applicator, or field hand on vegetable crops?
- Did you live near active farmland in an agricultural community?
- Were you pregnant while living or working in one of these areas?
- Did a child later develop unexplained developmental delays or thyroid-related health issues?
If you answered yes to any of these, it may be worth speaking with a doctor about your health and with us about your legal options. Writing down dates, addresses, and job details while they are fresh can make a real difference later.

FAQs about Dacthal Exposure
Here are answers to some of the questions we hear most often from Florida workers and families who are concerned about Dacthal exposure.
No, Dacthal is no longer legal to sell, distribute, or use anywhere in the country. The EPA suspended it in August 2024 and finalized a full cancellation in October 2024, and that order even bars the use of any leftover product still sitting on a shelf.
The gravest and most studied risks involved unborn babies, but Dacthal is known to affect the thyroid, which matters for adults too. An adult with a history of heavy exposure who later develops thyroid trouble or other health issues should talk with a doctor about that history.
There is no single test that confirms a Dacthal connection, so your family’s history is the key. If you were exposed during pregnancy and your child has thyroid problems, developmental delays, or a low birth weight with no other clear cause, the situation is worth a closer look.
No. We handle injury cases on a contingency basis, which means there is no charge to speak with us and no fees unless we win your case. That way, cost is never the reason a family stays quiet about a serious harm.
Yes. Florida law sets deadlines for filing injury claims, known as the statute of limitations, under Florida Statutes Section 95.11, and missing that window can end a case before it begins. Because exposure claims can be tricky to date, it is best to ask about your specific situation as soon as you can.
Responsibility often points to the company that made and sold the herbicide, which later agreed to pull it from the market. Claims generally focus on whether that company failed to warn people about risks it knew or should have known about, and a review of your circumstances can help identify who may be accountable.
