Humans that are infected with Salmonella may have symptoms such as nausea, vomiting, diarrhea or bloody diarrhea, abdominal cramping, and fever. Salmonella infections can also result in more serious conditions such as arterial infections, endocarditis, arthritis, muscle pain, eye irritation, and urinary tract symptoms. Consumers that have these symptoms should see their healthcare provider.

Pets that are infected with Salmonella may be lethargic, have diarrhea or bloody diarrhea, fever, and vomiting. Some pets may have decreased appetite, fever, and abdominal pain. Some pets may be carriers of Salmonella and can infect humans as well as other animals. Pets that show symptoms of Salmonella should visit a veterinarian for medical treatment.

Dog Goods USA was notified of the Salmonella contamination after the FDA sampled its pig ears, which tested positive for Salmonella. It is also conducting its own investigation into the source of the Salmonella contamination. The company has not received any reports of illness related to the recall.
