(eg. description of the frequency and severity of the symptoms
On August 8, 2014 the caller found a dead rat and the caller's son explained what he had done with the product. Later that day, he contacted the Animal Product Safety Service (APSS). The caller stated they also have 2 barn cats that have been missing for days, but there have also been local reports of coyotes, so he thought a predator had gotten the cats, as no bodies have been found. The caller's wife also has a pet raccoon that has access to the hog barn, but the racoon was in there last night and is acting normally that day. The caller stated they perfomed environmental decontamination (already swept up the bait and disposed of it, but there may still be some residue on the floor or rinsed into the waste holding reservoir). The APSS veterinarian stated methomyl is a hot carbamate. The APSS veterinarian also stated death usually occurs rapidly with a lethal exposure. The APSS veterinarian also stated it has a narrow margin of safety. The APSS veterinarian further stated to reach LD50 for an average sized rat it would only take about 1.3 grams (g) of bait and for dogs, 0.5g bait per kilogram is enough to reach the LD50 for dogs. The APSS veterinarian further stated once in the waste reservior, the residue is likely to be dilute enough that it will not pose a serious risk and once spread out in soil/ground, would breakdown rapidly. The APSS veterinarian recommended environmental decontamination (breaks down rapidly in alkaline environment so would wash the floor where the product was located with a cleaning product pH 7-9 and would also consider foot baths out of the area for a few days as well). The APSS veterinarian also recommended preventing further exposure. A necropsy was not available.
Death
The APSS veterinarian stated that the substance was considered to have an unknown likelihood of causing the clinical situation. A follow up was not performed, because additional information was not expected. Extra Label Use: Not to be used in area accessible to animals.
