Omethoate works by inhibiting the enzyme acetylcholinesterase. This inhibition over-stimulattes parts of the nervous system that rely on acetylcholine to transmit nerve impulses. ^[1]

It is an irritant to the skin and mucous membranes. Its toxicity and hazard potential are still under review because of concerns about its safety.^[2] Additionally, it cannot be used on food products.

The acceptable daily intake (ADI) has been amended from 0.0003 to 0.0004 mg/kg bw ^[1]
