Prallethrin is classified as “Not Likely to be Carcinogenic to Humans.” No tumors were observed in rat and mouse carcinogenicity studies up to the highest doses tested. In both the rat and mouse studies, the animals could have tolerated higher dose levels; however, EPA determined that dose levels were adequate to assess potential ...

Carbaryl is a cholinesterase inhibitor and is toxic to humans. It is classified as a likely human carcinogen by the United States Environmental Protection Agency (EPA.) [13] The oral LD 50 is 250 to 850 mg/kg for rats and 100 to 650 mg/kg for mice. [8] Carbaryl can be produced using methyl isocyanate (MIC) as an intermediary. [5]
The primary antidote to brodifacoum poisoning is immediate administration of vitamin K 1 (dosage for humans: initially slow intravenous injections of 10–25 mg repeated at 3–6 hours until normalisation of the prothrombin time; then 10 mg orally four times daily as a "maintenance dose").

In humans, cypermethrin is deactivated by enzymatic hydrolysis to several carboxylic acid metabolites, which are eliminated in the urine. Worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdosage may be confirmed by quantitation of cypermethrin in blood or plasma.
