Natura Pet Products, which issued a recall of select lots of four brands of pet food last month, has expanded its recall to include all of the company’s dry pet food and treat products with expiration dates through March 24, 2014. The recall was initiated after the Michigan Department of Agriculture discovered Salmonella in a sample taken from a pet food bag, and was expanded after both that agency and the Georgia Department of Agriculture discovered Salmonella in more dry pet food and a cat treat. In addition to the four brands subject to the initial recall: California Natural, EVO, Healthwise and Innova, Natura has included its Karma brand products in this latest recall. Go here for a full list of recalled products. No wet food or biscuits are affected by this recall, according to the company. Products subject to this recall were sold through veterinary clinics and certain pet specialty retailers nationwide and in Canada, Hong Kong, Korea, Japan, Malaysia, Singapore, Australia and Costa Rica, as well as online. “Pets with Salmonella infections may be lethargic and have diarrhea or bloody diarrhea, fever, and vomiting,” according to the U.S. Food and Drug Administration. “Some pets will have only decreased appetite, fever and abdominal pain.” Pets can be carriers of Salmonella without showing symptoms and can infect other animals or humans, notes FDA. “If your pet has consumed the recalled product and has these symptoms, please contact your veterinarian,” advises the agency. Consumers who have purchased these products should discard them or contact the company for a refund.
