What is a common symptom that may indicate pesticide exposure?

Nausea is a common symptom that can indicate pesticide exposure because many pesticides contain chemicals that can disrupt the digestive system. When a person is exposed to these substances, either through inhalation, skin contact, or ingestion, the body may react by triggering feelings of nausea. This reaction can be part of the body's defense mechanism, signaling that something harmful has entered the system and causing discomfort as it tries to expel the toxins.

Coughing can also occur due to respiratory irritation but is less specific as a symptom of pesticide exposure. A rash may indicate skin irritation, which can occur from certain pesticides but is not as commonly associated with general exposure as nausea. Fatigue can be a symptom related to many health issues, including illness or stress, and is too broad to pinpoint pesticide exposure specifically. Therefore, nausea is a more distinct indicator directly linked to the ingestion or absorption of harmful pesticide chemicals.
