What is the first symptom of metaldehyde toxicity?

The first symptom of metaldehyde toxicity is vomiting. Metaldehyde is commonly found in products used for pest control, particularly snail and slug baits. When ingested, it affects the central nervous system and can lead to acute gastrointestinal distress. Vomiting often serves as the body's initial response to the toxin, aiming to expel the harmful substance from the system.

Understanding the progression of symptoms following exposure is crucial for proper diagnosis and treatment. After vomiting, other symptoms may develop, such as diarrhea or neurologic manifestations like seizures, but vomiting is the earliest indication that metaldehyde is causing harm. This knowledge helps veterinary professionals identify and manage cases of toxicity effectively, ensuring timely intervention to mitigate the effects of the toxin.
