Pet Food Recall: Purina

On occasion, the Food and Drug Administration will implement a pet food recall Pet Food Recall: Purinadue to manufacturing inconsistencies in the production of cat and dog food.

The Wall Street Journal MarketWatch reported on May 12, 2012 that Nestle SA is recalling one lot of Nestle Purina PetCare’s Purina Veterinary Diets Overweight Management (OM) canned cat food due to low levels of thiamine (vitamin B1).  The low level was detected by the U.S. Food and Drug Administration and applies to Purina OM canned cat food with a “best by” date of June 2013 and the production code 11721159, which was distributed to veterinary hospitals between June 2011 and May 2012 in the United States and Canada.  The Purina OM canned cat food is a prescription diet, and can only be purchased with a prescription from a veterinarian. A list of pet foods that have been recalled by the FDA can be found here.

Thiamine (vitamin B1) in pet food recall

Thiamine is an essential vitamin for cats that may develop problems if fed a thiamine deficient diet for several weeks.  In cats, thiamine deficiency can cause neurological signs such as posture changes or ataxia and short convulsion seizures.  It can cause decreased appetite, decreased heart rate, progressive weakness, and death.  Some veterinarians advise supplement of thiamine (100-200 mg/day) in cats with hepatic lipidosis (fatty liver syndrome).  Cats with heart disease on large doses of diuretics are thought to be at some risk of thiamine deficiency due to increased urinary loss of this water soluble vitamin.  However, most commercial feline diets contain relatively high levels of thiamine, so the need for supplementation is questionable.  If a cat with heart disease is on high dose diuretics and is anorexic, than supplementation of the diet with thiamine may be useful.
