What is one reason to perform cholinesterase testing on pesticide applicators?

Performing cholinesterase testing on pesticide applicators is important to monitor the effects of exposure to pesticides, particularly those that inhibit the enzyme acetylcholinesterase. This enzyme plays a crucial role in the nervous system by breaking down the neurotransmitter acetylcholine. When pesticide exposure occurs, particularly from organophosphates and carbamates, it can lead to a decrease in cholinesterase levels, indicating potential overexposure and toxicity.

Regular testing can help identify individuals who may be at risk of significant health effects from exposure. By ensuring that cholinesterase levels remain within a safe range, employers can take necessary precautions to protect workers' health, such as modifying work practices or providing additional training and protective equipment. This proactive approach helps prevent the onset of acute or chronic health issues related to pesticide exposure.
