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, 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 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.
