Potential Health Effects of Pesticides

Insecticides cause the greatest number of pesticide poisonings in the United States. The most serious pesticide poisonings usually result from acute exposure to organophosphate and carbamate insecticides. Organophosphate insecticides include chlorpyrifos, diazinon, dimethoate, disulfoton, malathion, methyl parathion, and ethyl parathion.

Insecticide Toxicity in Cats | PetMD

Dec 17, 2008·Organophosphate and Carbamate Toxicity. Areas that are geographically prone to heavy flea and tick infestations tend to use many different forms of insecticide (e.g., organophosphates and carbamates). But exposure to insecticides -- especially after heavy or repeated applications of the chemicals -- may be toxic to cats.

Organophosphate and Carbamate Poisoning | JAMA Internal ...

Organophosphate insecticides may cause serious poisoning either accidentally or by deliberate ingestion. Toxic symptoms are produced by acetylcholine accumulation at cholinergic receptors. Diagnosis is based on history of exposure or ingestion, symptoms and signs of cholinergic overactivity and a decrease in serum pseudocholinesterase levels.

PI221/PI221: Pesticides and Cholinesterase

Exposure to carbamate and organophosphate pesticides inhibits cholinesterase, resulting in continual overexcitation of nerve-to-nerve and nerve-to-muscle communication. Extreme exposure to pesticides that inhibit cholinesterase — exposure resulting, for example, from spilling concentrates on oneself — can cause immediate illness.

carbamate compounds that are candidate pesticides be tested in susceptible animal species for this neurotoxic property. In addition to acute poisoning episodes and OPIDN, an intermediate syndrome has been described. This syndrome occurs after resolution of the acute cholinergic crisis, generally 24–96 hours after exposure.
