Merrick Recalls Treats Due To Thyroid Hormone Concerns
Merrick Pet Care has issued a voluntary recall of beef dog treats because of concerns the treats may contain elevated levels of a thyroid hormone.
Merrick Pet Care has launched the voluntary recall because they’re concerned some of the treats may have elevated levels of a beef thyroid hormone that is naturally occurring. The products were distributed in the United States in brick and mortar stores as well as online, and there was a small distribution of the treats in Canada as well.
The thyroid of concern most likely came from laryngeal tissue (animal gullets) that had still had remnants of the thyroid glands. The USDA prohibits the use of any part of thyroid glands and laryngeal muscle tissue in human food, but gullets are allowed to be used in pet foods and treats.
Unfortunately, not completely removing the thyroid glands from the gullets may cause the treats to have elevated levels of thyroid hormones in the products, and in turn, can cause symptoms in dogs who consume the treats. Dogs who have taken in high levels of beef thyroid hormones may experience increased thirst and urination, weight loss, restlessness and increased heart rates. Over time, exposure to the elevated thyroid levels may cause symptoms to become more severe, and can include vomiting, diarrhea and labored breathing.
The company decided to launch the recall after notification that a dog was adversely affected after it ate one of Merrick’s Backcountry Great Plains Real Beef Jerky treats. Once they dog stopped consuming the treats, the dog was fully recovered.
Dogs that consume high levels of beef thyroid hormone may experience symptoms such as increased thirst and urination, weight loss, restlessness and increased heart rate. Exposure to the hormone over an extended period of time may cause an increase in the severity of the symptoms, including vomiting, diarrhea, and rapid or labored breathing.
