Farmers using medicines containing gentian violet on their animals, or themselves, should stop immediately, said Health Canada last month.
The antiseptic is typically used to treat fungal infections such as oral thrush in children, or for treating surface wounds or eye infections in cattle and poultry. Last month, Health Canada completed a safety review and found that the product might increase the risk of cancer.
As of April, there were four veterinary products that contained gentian violet: Blu Kote Dr. Naylors, Cristisol, Guard and Wound Spray, and Wound Clear Spray. These products have been recalled. Farmers who have any of these antiseptics should stop using them and consult their veterinarians on the best way to dispose of them, Health Canada advises.
