Captan is a fungicide. It is used on a variety of agricultural and greenhouse food/feed crops, indoor non-food uses, seed treatments and ornamental plant sites. People who mixed captan products or worked in fields where captan had been applied reported eye and skin irritation. A few human volunteers reported skin irritation and allergic reactions after captan was applied to their backs. Captan was previously cited as Group B2, a probable human carcinogen by the US Environmental Protection Agency (EPA), but was reclassified in 2004. The EPA now states: “Captan is not likely to be a human carcinogen nor pose cancer risks of concern when used in accordance with approved product labels.”
