Which of the following is NOT an early sign of pesticide poisoning?

Memory loss is considered a more advanced or severe symptom of pesticide poisoning rather than an early sign. Early signs typically manifest as more immediate physiological reactions to pesticide exposure, such as headaches, vomiting, and severe dizziness. Headaches can occur quickly due to the nervous system's response to toxins. Vomiting is a common bodily reaction when the body tries to expel harmful substances. Severe dizziness may indicate a significant impact on balance and coordination, also typical early signs of exposure to toxic substances.

In contrast, memory loss tends to relate to prolonged exposure or more severe poisoning that affects the central nervous system, rather than being an immediate response. Understanding these symptoms is crucial for identifying pesticide poisoning early and taking appropriate action, highlighting the importance of recognizing the immediate effects over more chronic ones.
