At the request of the United States Food and Drug Administration, Nestle Purina PetCare has issued a voluntary recall for a single production lot of its feline food products due to the possibility that these products do not contain the amount of feline nutrients specified on their ingredients labels. A consumer report prompted the Food and Drug Administration to perform product testing on Nestle’s Purina Veterinary Diets OM Overweight Management canned cat food. The sample test revealed that 5.5 ounce cans of Purina Veterinary Diets OM Overweight Management cat food marked with universal product code 11721159 38100 – 13810 and imprinted with a June 2013 best buy date may not contain the required amount thiamine dictated by Food and Drug Administration guidelines regulating the ingredients of pet food. These canned food products were distributed for sale at veterinary clinics from June 2011 to May 2012. Cats fed only Purina Veterinary Diets OM Overweight Management containing insufficient thiamine for a period of several weeks may become thiamine deficient, a condition with symptoms including weight loss, salivation, loss of appetite, and vomiting. Consumers who have purchased the product affected by this recall should discontinue its use and take any felines given food from this production lot exhibiting any of the symptoms listed above should take them to a veterinarian for examination. Currently no other Purina pet food products or production lots are affected by this recall.
