| Comments |
Allergic contact dermatitis reported in farmers; [Kanerva, p. 1152] Pyrethroids have low toxicity to humans after dermal exposure. Of 573 dermal or ingestion poisoning cases in China, 51 patients had disturbed consciousness and 34 had seizures. Of those, only five were occupationally exposed. Seizures are more commonly related to exposures to fenvalerate, flucythrinate, cypermethrin, deltapermethrin, and fluvalinate. Seizures have not been reported after exposure to permethrin. Pyrethroids may also cause paresthesias after skin contact. Paresthesias (stinging and numbness) usually begin 1-2 hours after contact and resolve within 24 hours. [EPA Pesticides, p. 87-8] Pyrethrins cause liver injury when fed to animals at high doses. [EXTOXNET] |
