Results show carbofuran, an insecticide, as well as traces of strychnine and pentobarbital were found in the dog's tissues. Only pentobarbital was found in the cat's system. It's considered a "euthanasia" drug.
An MSU report states "Carbofuran is highly toxic to birds...(with) one granule sufficient to kill." Birds could have eaten the substance which resembles seeds in size and shape, or as part of the food chain when scavengers fed on other small birds or mammals exposed to the pellets.
Public health officials say there haven't been any reports of human illness from the toxins, but several area agencies are investigating to determine if the poisonings were intentional or not.
A rash of animal deaths were reported in February in the Jamaica area. Five dogs, 1 cat, 1 skunk and several birds were found.
