Pet Food Recalled After Salmonella Link Suspected.

Two isolated cases of a type of the salmonella bacterium known as Salmonella Schwarzengrund in humans has caused a Pennsylvania pet food manufacturer to recall a number of dry dog and cat food brands nationwide.

Mars Inc.'s Mars Petcare is recalling cat and dog food made at its Everson, Pa. facility, according to wire service reports.

While Mars Inc. maintained no direct connection has been made between illness in either animals or humans and its pet food product, the possibility that two humans may have contracted salmonella caused the recall, which began at the beginning of August.

The latest announcement expanded the pet food brands being recalled to include some Pedigree brands, Country Acres, Retriever, Doggy Bag, Members Mark, Natural, Ol' Roy, Special Kitty, Paws & Claws, Wegman's, Pet Pride, PMI Nutrition and Red Flannel.

Consumers should look for "17" as the first two digits of the second line on the Universal Price Code. Pedigree products will have "PAE" on the bottom line. Consumers can also call 1-877-568-4463 for more information.

Salmonella Schwarzengrund is one member (serovar) of the salmonella family. According to the U.S. Food and Drug administration, symptoms in humans include fever, diarrhea (which may be bloody), nausea, vomiting and abdominal pain. Animal symptoms include lethargy, diarrhea (sometimes bloody), fever, and vomiting. Some pets will only have decreased appetite, fever or abdominal pain.
