What is the primary cause of pesticide poisoning for applicators?

The primary cause of pesticide poisoning for applicators is skin contact. Pesticides can be absorbed through the skin, leading to systemic exposure that results in poisoning. When applicators mix, load, or apply pesticides, their skin can come into contact with the chemicals, especially if protective gear is not used properly or if there is a spill.

This mode of exposure is particularly concerning because skin absorption can occur quickly and lead to significant health effects, depending on the toxicity of the pesticide and the duration of exposure. Proper training and the use of personal protective equipment are essential for minimizing this risk and ensuring safe handling practices when working with pesticides.

Other factors like inhalation of fumes, ingestion through contaminated food, and improper storage also pose risks, but skin contact is the most direct and prevalent pathway for applicators during their work.
