Accidental ingestion/Ingestion accident.
(eg. description of the frequency and severity of the symptoms
On August 9, 2019, the dog was found with the product package in her mouth. Within five minutes, the dog developed trembling and hypersalivation. The owner then took the dog to the regular veterinarian. Shortly after, the dog developed hyperthermia, with a temperature of 104.18 degrees Fahrenheit (F). The regular veterinarian then gave the dog fluids. About ten minutes later, the dog developed tremors and tachycardia, with a heart rate of 160.0 beats per minute (bpm). The regular veterinarian then gave the dog maropitant (Cerenia). The dog was then transfered to an emergency veterinarian who gave methocarbamol (50 milligrams per kilogram (mg/kg)). Soon after, the emergency veterinarian contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated that methomyl (Golden Malrin) is a carbamate that is rapidly absorbed after ingestion, but does not accumulate in the tissues and that it does not "age" on the receptors like organophosphates (OPs) do, so signs are often short-lived. The APSS veterinarian also stated that signs occur within minutes after ingestion, and include salivation, lacrimation, urination, diarrhea, dyspnea, and emesis (SLUDDE) signs, bradycardia, ataxia, weakness, tremors, seizures, and possibly death. Finally, the APSS veterinarian stated that if not a lethal exposure, signs often resolve spontaneously due to the reversible nature of carbamate toxicity. The APSS veterinarian recommended the emergency veterinarian provide fluid therapy, give methocarbamol (continue 0.5-1.0 milliliters (mL) intravenous (IV) at a time until tremors stop, repeat as needed), give diazepam (for tremors, seizures), monitor for central nervous system signs, monitor body temperature, monitor cardiovascular function, give atropine (only for significant bradycardia or bronchial secretions: 0.1-0.2 mg/kg: 1/4-1/3 IV the rest intramuscular (IM) or subcutaneous (SC)), monitor electrolytes (baseline sodium if charcoal is given), give activated charcoal (only if safe to give: 1 mg/kg with sorbitol), provide symptomatic care, provide supportive care, and to call back with questions.
Moderate
The bait should not have been anywhere that pets would have access to.
