Hill’s Pet food recall and signs of elevated levels of vitamin D
Hill’s Pet Nutrition announced yesterday they were voluntarily recalling select canned dog food products due to potentially elevated levels of vitamin D. Vitamin D is an essential nutrient for dogs but overdose of vitamin D can lead to health issues depending on the level of Vitamin D and length of exposure. Clinical signs of vitamin D overdose include increased thirst and urination, anorexia, vomiting, excessive drooling and weight loss. Clinical signs of vitamin D overdose often reflect the resultant hypercalcemia.
Testing includes measurement of calcium and phosphorus and endocrine panels to measure parathyroid levels, ionized calcium and 25 Hydroxyvitamin D (25-hydroxycholecalciferol). Veterinarians should contact the manufacturer of the recalled pet food for more information on testing and handling of the recalled product. Treatment consists of removing the food and providing supportive care.
If hypercalcemia is detected on routine testing of a canine, veterinarians should inquire as to whether any of the recalled canned food is being fed so as to avoid the mistaken assumption of neoplasia (or hyperparathyroidism) being present in these cases.
The AVMA maintains a complete list of all pet food recalls, which can be accessed at their website.
