Pig Ears and Salmonella
Pig ears may carry Salmonella bacteria, so it may cause gastrointestinal infection. The infection can be signaled by abdominal pain, vomiting, diarrhea and lethargy. In some dogs, the Salmonella may not present any initial symptoms. You should make sure that the pig ears are from a trustworthy source. Typically, pig ears should get heat treatment for half a day, so that all potential bacteria will be eliminated.
The Salmonella infection is a zoonotic disease, which can be transmitted from dogs or pigs to humans, so you should be careful when handling the dog’s feces. Also, wash your hands after handling the pig ears, as you may contract the bacteria from these as well. You may also use gloves for protection.
