Vitamin D toxicity associated with Blue Buffalo dog food, recall issued
Blue Buffalo Co. has recalled certain dog foods that may contain excess vitamin D, which can cause hypercalcemia.
On Oct. 8, 2010 a team at Michigan State University announced it had found that 16 dogs with hypercalcemia also had high concentrations of vitamin D in their blood and ate a diet of Blue Buffalo's Wilderness Chicken dog food. The dogs seemed to recover with a change in diet.
Blue Buffalo issued a recall Oct. 8, 2010 of certain product runs of Wilderness Chicken, Basics Salmon, and Large Breed Adult Chicken dog foods. A letter states that the company believes certain products may contain excess vitamin D because an ingredient supplier made a vitamin D supplement immediately prior to making ingredients for the products.
A press release on the website of the Food and Drug Administration reports a total of 36 cases of dogs displaying signs consistent with elevated vitamin D after consuming food from the product runs in question. The signs subsided with a change in diet.
The Blue Buffalo letter states that the recall applies to the following dog food:
Blue Buffalo will reimburse veterinary expenses in relation to illness resulting from consumption of these products. Consumers may contact the company at (877) 523-9114.
