However, consumers who use pesticides in their homes may also be overexposed, especially if they do not follow carefully the instructions on the container label. Recognizing Pesticide Poisoning. Like other chemicals, pesticides may produce injury externally or internally.
Pesticides can cause contact-associated skin irritation or allergies .
Symptoms of irritation include redness, itching, or pimples. Allergic skin reactions may produce redness, swelling, or blistering. The mucous membranes of the eyes, nose, mouth, and throat are also quite sensitive to chemicals. Stinging and swelling can occur. Internal injuries may occur depending upon where a chemical is transported in the body or what organ is affected.
