The company said a U.S. Food and Drug Administration test detected salmonella bacteria in a random sample. Salmonella can affect animals, and people handling dry pet food can become infected with salmonella, especially if they have not thoroughly washed their hands after having contact with surfaces exposed to the product.
Pets infected with the bacteria can become 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.
The Pacoima, Calif, company said the recalled dog food was distributed by pet specialty stores in Alaska, Arizona, Arkansas, California, Colorado, Hawaii, Idaho, Illinois, Iowa, Kansas, Louisiana, Minnesota, Mississippi, Missouri, Montana, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Washington, Wisconsin and Wyoming.
Officials said only Natural Balance Sweet Potato & Chicken Dry Dog Food sold in 5- and 28-pound sizes with a "Best By" date of June 17, 2011, is involved in the recall.
Consumers can return the recalled product for a refund or contact the company for additional information at 800-829-4493.
