TOXICOLOGY: Cyfluthrin is considered moderately toxic to mammals. The oral dose of cyfluthrin that resulted in mortality to half of the test animals (LD50) ranged from 869 - 1271 mg/kg in rats, 291 - 609 mg/kg in mice, >1000 mg/kg in sheep, > 100 mg/kg in dogs and > 1000 mg/kg in rabbits. In inhalation toxicity tests with rats, the concentration of cyfluthrin in air that resulted in mortality to half of the test animals (LC50) was >1,089 ug/l in 1 hour tests, and ranged from 469 - 592 ug/l in 4 hour tests. Although cyfluthrin is an irritant to human skin, especially facial skin, it is not considered to have high dermal toxicity. The dermal LD50 in tests with rats was > 5,000 mg/kg, and was not found to be a skin irritant or sensitizer in guinea pigs and rabbits.
