Methyl parathion gets into the bloodstream and from there goes to the liver, brain, and other organs. The liver breaks some of the methyl parathion down to a more harmful chemical, methyl paraoxon. Methyl parathion and methyl paraoxon can bind to enzymes in nerves within minutes or hours.

Among the most extremely acutely toxic pesticides, parathion is notorious for the number and severity of human poisonings it causes each year. In addition to its acute toxicity, there is evidence that parathion is a chronic neurotoxin, carcinogen.
