TSE’S – U.S. enforcement strategies and what they mean to you


Hoestenbach, Jr. RD. 1999. TSE’S – U.S. enforcement strategies and what they mean to you. In Proceedings of the Third Conference on Zoo and Wildlife Nutrition, AZA Nutrition Advisory Group, Columbus, OH.


In response to concerns by the World Health Organization, and various other authorities around the globe, over the threat of additional transmissible spongiform encephalopathy epidemics, Federal regulation now prohibits the use of proteins derived from mammalian tissue in feed for ruminant animals. This regulation removes those animal proteins from Generally Recognized As Safe status and relocates them as food additives subject to the various restrictions imposed by the regulation. This regulation has aspects that potentially affect all animal feeds. As new evidence surfaces regarding both the causal agent(s) and the scope of the diseases, suggesting that more zoo animals may be susceptible than previously thought, understanding the regulation and its individual elements for compliance becomes increasingly important for zoo personnel.
