Rockville, Md. -- While no pets have been reported ill, the Food and Drug Administration expanded its list of recalled pet-food products with contaminated peanut butter.

The agency reports in a prepared statement, "The Food and Drug Administration (FDA) continues to investigate potential Salmonella contamination of peanut butter and paste made at the Blakely, Georgia facility of Peanut Corporation of American (PCA), and is informing pet owners that the recall also includes some pet food products."

Companies that received peanut butter or peanut paste from PCA have in turn issued recalls. A searchable list of all pet food products involved in the recall can be found at FDA.com.

The agency reports that the investigation continues and officials will continue to update the list of recalled products as information becomes available. FDA advises pet owners to wash their hands with hot water and soap before and after handling pet foods and treats. Pet food bowls and utensils should also be washed after each use.

Pets with Salmonella infections may be lethargic and have diarrhea or bloody diarrhea, fever and vomiting. Some pets will show signs of decreased appetite, fever and abdominal pain. Well animals can be carriers. If your pet consumed the recalled product and has these symptoms, FDA suggests you contact your veterinarian.
