The U.S. Food and Drug Administration is investigating the presence of elevated, potentially toxic levels of vitamin D in several dry pet foods.
The FDA has become aware of reports of vitamin D toxicity in dogs that ate dry dog food common contract manufacturer and marketed under several different brand names. This is a developing situation, and the FDA will update with additional information as it becomes available.
Excess vitamin D in the diet can cause vomiting, loss of appetite, increased thirst, increased urination, excessive drooling, and weight loss. Vitamin D at toxic levels can cause kidney failure and death. Pet owners whose dogs have been eating the recalled brands and are showing these symptoms should contact their veterinarians.
After receiving complaints from pet owners about dogs with vitamin D toxicity, one of the firms reported to the FDA that it was recalling dry pet food due to potentially toxic levels of vitamin D. Many other brands with a common contract manufacturer have also been recalled. The FDA is working with the contract manufacturer to provide a comprehensive list of affected brands.
FDA scientists are still analyzing reports and the information currently available to determine whether the illnesses are definitively connected to diet.
FDA scientists have evaluated samples of some of these products, and State and private lab test results indicate that the food contained as much as approximately 70 times the intended amount of vitamin D. Consuming food with such high levels of vitamin D is potentially toxic to dogs and in severe cases may lead to kidney failure and/or death.
