Imagine dedicating your life to farming, only to have your health stolen by the very tools you trusted. This is the heartbreaking reality for Mac Barlow, an Alabama farmer who now battles Parkinson’s disease—a condition he and thousands of others blame on a widely used weed killer.
About a decade ago, Mac began noticing unsettling changes in his body. His once-steady feet became unsteady, his hands trembled, and simple tasks like gripping objects became a struggle. At first, he chalked it up to the natural aging process, especially after decades of hard labor on his family farm in Opp, Alabama, where he grew peanuts, soybeans, and corn. But a chance encounter with a neighbor diagnosed with Parkinson’s changed everything. She asked if he’d ever used paraquat, a potent but deadly herbicide. And this is the part most people miss: that moment of realization was the beginning of a journey that would lead him to join over 6,200 people suing the manufacturer of this controversial chemical.
Now 70, Mac was diagnosed with Parkinson’s a few years ago. He recalls using paraquat on and off for nearly 40 years, starting in the 1980s. ‘If I knew it was going to be that bad, I would have tried to figure out something else,’ he told AL.com. Paraquat, known for its ability to rapidly clear fields without disturbing the soil, was a convenient choice for farmers like Mac. But its convenience came at a cost. Despite being banned in dozens of countries, including the United Kingdom and even China where it’s produced, paraquat remains legal in the United States and other nations. Its manufacturer, Syngenta, a subsidiary of a Chinese government-owned company, continues to defend its product, claiming no scientific evidence directly links paraquat to Parkinson’s. But here’s where it gets controversial: while Syngenta insists paraquat is safe when used as directed, thousands of farmers like Mac tell a different story.
Mac’s farming roots run deep. He struck out on his own in 1975, married his high school sweetheart Miriam in 1976, and together they built a life on their cluttered-but-cozy farmhouse surrounded by hundreds of acres of green fields. In 1998, they were even named ‘Farm Family of the Year’ by the Opp Chamber of Commerce. Their daughter, Kristee, followed in their footsteps, winning first place in 4-H for her peanut crop. Paraquat was a staple in their farming routine, used once or twice a year to clear fields and control weeds. Mac took precautions—long sleeves, boots, a mask, and careful mixing—but the chemical’s distinct odor lingered on his skin and clothes, a constant reminder of its presence. And this is the part most people miss: despite his efforts, Mac believes years of exposure to paraquat led to his Parkinson’s diagnosis.
Syngenta argues that no peer-reviewed study has conclusively linked paraquat to Parkinson’s, but Mac and his lawyers disagree. They claim Syngenta knew or should have known about the risks but continued to market the product as safe. Attorney Elizabeth Walden emphasizes that the lawsuits are about standing up for families like the Barlows, whose lives have been upended by a dangerous product. ‘Behind every case file is a family facing unimaginable challenges,’ she said. But here’s where it gets controversial: if the courts rule in favor of the plaintiffs, it could set a precedent for holding corporations accountable for long-term health impacts of their products. What do you think? Should companies like Syngenta be held responsible, or is the lack of definitive scientific proof enough to absolve them?
Parkinson’s has taken a devastating toll on Mac’s life. Once a math whiz with neat handwriting, he now struggles with mental acuity and physical tasks. His passion for raising chickens had to be abandoned, and the family even sold some of their land to cover medical expenses. Miriam, his devoted wife and caregiver, battles her own health issues but remains by his side, embodying the vow ‘for better or worse.’ Their strong Christian faith has been a source of strength, helping them through unimaginable losses, including the death of their eldest grandson, JW, in an accidental shooting.
Paraquat’s dangers aren’t limited to long-term exposure. Accidental ingestion or contact can be fatal, with federal data reporting 132 exposures and three deaths in the U.S. in 2019 alone. Yet, it remains a tool many farmers rely on. And this is the part most people miss: while Mac’s story is tragic, it’s also a call to action. Should paraquat be banned outright, or is there a way to balance its benefits with its risks? Let’s continue this conversation in the comments—your perspective matters.
As Mac reflects on his journey, he hopes his lawsuit will bring about change. ‘Maybe it helps somebody else,’ he said. His story is a stark reminder of the human cost behind agricultural practices and the urgent need for safer alternatives. What’s your take? Share your thoughts below.
