Which symptom would NOT indicate a potential pesticide illness or injury?

Scratches on the arms or hands would not typically indicate a potential pesticide illness or injury. This symptom is more indicative of a physical injury, such as a cut or abrasion, rather than a reaction to pesticide exposure. The other options—nausea and vomiting, headaches, and dizziness—are common signs associated with pesticide poisoning or exposure. These symptoms could be related to acute or chronic effects of chemicals typically found in pesticides, and they point to the body's systemic response to harmful substances. Knowing that scratches can occur from various non-chemical-related activities further solidifies why they do not signify pesticide-related issues.
