Chronic Toxicity
Repeated or prolonged exposure may cause central nervous system effects.
Carcinogenicity
Bifenthrin: Not recognized as carcinogenic by Research Agencies (IARC, NTP, OSHA, ACGIH).
Did not show carcinogenic effects in animal experiments. Cypermethrin caused an increase in benign
lung tumors in mice, but not in rats, and was negative for genotoxicity. EPA has classified zeta
-
cypermethrin as a possible human carcinogen based on this information, but does not regulate based
on its low cancer risk.
Mutagenicity
Bifenthrin, Zeta-cypermethrin: Not genotoxic.
Reproductive toxicity
Zeta-cypermethrin: No toxicity to reproduction.
Neurological Effects
Tremors were associated with chronic exposure of laboratory animals to bifenthrin, which may
disappear with continued exposure. Cypermethrin did not cause neurotoxicity in animal experiments.
Developmental Toxicity
Bifenthrin, Zeta-cypermethrin: Not teratogenic in animal studies.
Target Organ Effects
Bifenthrin: A slight increase in male mouse urinary bladder tumors at the highest dose was probably
not of toxicological concern.
