Merrick dog treats recalled due to elevated thyroid hormone
By Phyllis Entis | May 24, 2018
Merrick Pet Care has announced a voluntary recall of certain Castor & Pollux and Merrick Backcountry dog treats after one of the products was found to contain elevated levels of beef thyroid hormone.
The problem was discovered as a result of a consumer complaint lodged with the US Food and Drug Administration.
