Which of the following symptoms would NOT be reasonable grounds to suspect the possibility of a pesticide illness or injury?

Scratches on the arms or hands would not typically indicate pesticide illness or injury. While they could be a result of various benign causes, such as minor accidents or environmental factors, they do not specifically correlate with the typical symptoms associated with pesticide exposure. Symptoms like headaches, blurred vision, and abdominal cramps, on the other hand, are more directly linked to pesticide poisoning or adverse reactions. Pesticides can affect the nervous system and bodily functions, leading to such symptoms, which makes them reasonable grounds for suspicion. In contrast, physical scratches do not reflect systemic effects and, therefore, do not warrant the same level of concern regarding pesticide contamination or illness.
