From a very reliable source, sorry I dont have the original article:
The FDA reported the alert followed a recent Center for Veterinary Medicine investigation into reports of three dogs in different households that showed signs of hyperthyroidism. Extensive testing on all three dogs showed elevated thyroid hormone in the blood, but ruled out thyroid cancer, and reference lab interviews with the dogs’ owners revealed that all three dogs had been fed one of two dog food products: BLUE Wilderness® Rocky Mountain Recipe™ Red Meat Dinner Wet Food for Adult Dogs and/or WellPet Wellness 95% Beef Topper for Dogs.
After the dogs stopped eating those foods for a few weeks, their clinical signs improved, and they returned to normal, the FDA said. An FDA lab tested unopened cans of both products and found that they contained active thyroid hormone, according to the advisory. The FDA concluded that the source of thyroid hormones likely was from the use of gullets from which the thyroid glands were not completely removed.
