WASHINGTON (AP) Ñ An Illinois company is recalling pet chews made of pig’s ears because they could be contaminated with salmonella. One illness, to a dog in Missouri, has been linked to the chews, called Pig Ears for Pet Treats. The product is being recalled by the Keys Manufacturing Co. Inc. of Paris, Ill. Salmonella can affect animals, and there is risk to people from handling contaminated pet products. The bacteria can cause serious and sometimes fatal infections in young children, elderly people and those with weakened immune systems. Symptoms include fever, diarrhea, nausea, vomiting and abdominal pain. Pets with salmonella may be lethargic and have diarrhea or bloody diarrhea fever and vomiting. The pet treats were distributed in Arkansas, Florida, Illinois, Indiana, Iowa, Kentucky, Louisiana, Michigan, Minnesota, Missouri, Ohio, Pennsylvania, Texas and Virginia. Consumers can return the pet treats to the place of purchase for a full refund.
