Antimicrobial/antifungal ingredient in pet-care and veterinary products; some industrial and institutional disinfectants. It can enter wastewater when washed down drains [1][2].

Using or applying products to pets, touching treated fur or surfaces, breathing mists during application, or workplace handling of concentrates; small amounts may reach indoor dust or water via wastewater [1][2].

Causes skin and eye irritation and is harmful if ingested; high doses have affected the nervous system, liver, and kidneys in animal studies; very toxic to aquatic organisms. Major agencies have not classified it as a human carcinogen due to limited data [1][2].

Workers handling concentrates, pet groomers and veterinary staff, young children who touch treated pets, and people with sensitive skin [1][2].

Check labels and consider alternatives; follow directions exactly; wear gloves and ventilate; keep products and treated pets away from children until dry; wash hands; dispose per label—don’t bathe pets in natural waters [1][2].
