The FDA and CDC are working together to investigate cases of Salmonella that have broken out reportedly due to contact with pig ears. As of now, the FDA is recommended you cease purchasing and feeding your pet any pig ear until further investigation can be done into which brands are involved in the outbreak.
Salmonella can affect animals eating the infected product and due to this there is also a risk to humans who may have handled the contaminated products, especially if they have not thoroughly washed their hands and any surface that may have been exposed to the product.
Healthy people infected with Salmonella should monitor themselves for some or all of the following symptoms: nausea, vomiting, diarrhea or bloody diarrhea, abdominal cramping and fever. Rarely, Salmonella can result in more serious ailments, including arterial infections, endocarditis, arthritis, muscle pain, eye irritation, and urinary tract infections. If you feel you may have been exposed and infected please contact your healthcare provider.
Pets with Salmonella infections may be lethargic and have diarrhea or bloody diarrhea, fever, and vomiting. Some pets will have only decreased appetite, fever and abdominal pain. Infected but otherwise healthy pets can be carriers and infect other animals or humans. If your pet has consumed the recalled product and has these symptoms, please contact your veterinarian.
