What is the most common route of pesticide applicator poisoning?

The most prevalent route of pesticide applicator poisoning is through the mouth, nose, and eyes. This mode of exposure includes ingestion of pesticide residues, inhalation of airborne particles or vapors, and irritation or absorption through the eyes. Each of these entry points allows pesticides to bypass the skin's protective barrier and enter the body more directly, increasing the risk of poisoning.

For instance, when pesticides are inadvertently ingested or inhaled during application, the active chemicals can quickly enter the bloodstream, leading to systemic toxicity. Additionally, if these substances come into contact with the eyes, they can cause severe irritation and potential damage, compounding the risk of adverse health effects.

While skin contact is also a plausible method of exposure, it tends to be less critical than inhalation or ingestion, as the skin can act as a barrier. Wounds, while they can be a route for absorption, are not as common due to the general use of personal protective equipment that minimizes direct contact.
