The company called OC Raw…DOES NOT use any gullets or tracheas or any form of the thyroid tissues in any of their meat sources !! If any one has any questions just email or call Oliva Hudson ..of OC Raw…I am very happy with the results of their raw diets so far…it is important to know what is in the meat trims,the raw companies are getting from the suppliers..if a company can’t verify this ..I won’t use them….I trust OC Raw..and also trust North West Naturals..who also verified they use nothing with thyroid tissue attached either….in their raw meats….
