The U.S. Food and Drug Administration is advising pet owners and caretakers, veterinarians, and the pet food industry to be aware that pet food and treats made with livestock gullets (meat from the throat region) have the potential to contain thyroid tissue and thyroid hormones. Pets that eat food or treats containing thyroid hormones may develop hyperthyroidism, a disease that is rare in dogs and usually triggered by thyroid cancer.
Symptoms of hyperthyroidism include excessive thirst and urination, weight loss, increased appetite, restlessness, hyperactivity, elevated heart rate, rapid and/or labored breathing, vomiting, and diarrhea. Continued exposure to excess thyroid hormones can cause damage to the heart and in some cases, death.
An approved medicated feed mill license is required for facilities that manufacture feed using Category II, Type A medicated articles or manufacture certain liquid and free-choice feed, using Category I, Type A medicated articles that must follow proprietary formulas or specifications.
