Glufosinate and Human Health

Evaluation of human dietary exposure to glufosinate and its breakdown products by the EPA showed that the greatest risk from glufosinate was from contamination of drinking water. However, observed levels of exposure were found to be below levels of concern and were not considered a reasonable adverse health risk. Based on rodent studies, glufosinate is classified as not likely to be carcinogenic in humans.

Glufosinate is a slight skin irritant and a severe eye irritant. EPA evaluation determined that short and intermediate term dermal exposure was not a concern if label personal protective equipment requirements, such as goggles and gloves, are utilized. The restricted entry interval for glufosinate treated areas varies among products, crops, and type of field activity.
