Winemaker Links Mystery Rash and Bowel Cancer to Glyphosate Exposure, Urges Public Warning

Published By DPRJ Universal | Published on Sunday, 26 April 2026

South Australian winemaker Nick Dugmore, 41, attributes a mysterious full-body rash and his subsequent stage four bowel cancer diagnosis to glyphosate exposure. He experienced the severe rash in 2022 after unknowingly sleeping on sprayed land, months before his diagnosis. Now, Dugmore is urgently warning Australians about the chemical's 'slow and insidious' presence in everyday life, advocating for a national re-evaluation of glyphosate use, despite regulatory bodies maintaining its safety when directed. His personal investigation connects the timeline of his symptoms to potential chemical exposure.

South Australian winemaker Nick 'Duggie' Dugmore, 41, is raising an urgent warning following his stage four bowel cancer diagnosis, which he believes is linked to glyphosate exposure. In 2022, Dugmore suffered a mysterious, full-body rash after unknowingly sleeping on land sprayed with the widely used weed killer. The rash escalated dramatically, causing unbearable itching and facial swelling that left him sleepless for six nights, with doctors unable to pinpoint a cause at the time.More than a year later, in 2023, Dugmore was diagnosed with stage three bowel cancer, with doctors estimating the tumour had been growing for 14 to 16 months. He later realized this timeline closely matched his experience with the severe rash, prompting him to investigate glyphosate. He now believes chronic, low-level exposure to the chemical, found in food and water, may disrupt the body's biological processes, particularly in the gut. While the scientific community remains divided, Dr. Stephanie Seneff of MIT supports concerns, suggesting glyphosate can interfere with protein synthesis and the shikimate pathway.Despite regulatory bodies like the Australian Pesticides and Veterinary Medicines Authority reapproving glyphosate, citing insufficient evidence for restriction, Dugmore highlights that 33 other countries have banned it. His cancer has since progressed to stage four, with small metastases in his lungs. Now, Dugmore is actively advocating for a national review of glyphosate use and presenting to local councils, urging Australians to question their exposure and think critically about environmental systems. His story emphasizes a personal connection between unexplained symptoms and widespread chemical presence, driving a call for greater public awareness and systemic change.
