  1. TSE Advisory CommitteeOctober 25, 2001 Topic 3 • Center for Food Safety and Applied Nutrition Food and Drug Administration • Washington, DC 20204

  2. Topic 3 • Bovine Brain, Spinal Cord, and Other Neurological Tissue in Foods, Drugs, and Cosmetics for Human Use

  3. Purpose • To determine the benefit, if any, of restricting the use of bovine neurological tissues and products derived from these tissues in foods, drugs, and cosmetics for human use

  4. Background • Neurological tissues are the most highly infective tissues in BSE-infected cattle. • These tissues may be used as human food and may be used in a variety of FDA-regulated products. • FDA is not aware of any practical analytical tests for detecting the BSE agent in ingredients or products.

  5. FDA Authorities • Public Health Service Act: Make and enforce regulations to prevent introduction, transmission, or spread of a communicable disease. • Federal Food, Drug, and Cosmetic Act: Ensure the safety of cosmetics, food (including dietary supplements) and feed, drugs (including animal drugs), vaccines, biologics, blood products, and medical devices.

  6. USDA Regulates: • Most meat (beef, pork, lamb, horse, goat) • Poultry • Egg products (liquid, frozen, and dried)

  7. Question 1

  8. Question 2 • Is there a consistent and appreciable difference in infectivity of various sections/areas of bovine brain? If so, what are the differences in relative degrees of infectivity of these areas?

  9. Question 3 • Are there other bovine neurological tissues that, if used in consumer products (such as foods, dietary supplements, cosmetics, and certain non-application drugs), could also pose a significant health hazard? If so, what are the differences in relative degrees of infectivity of these tissues?

  10. Question 4 • What physical, chemical, or biological factors of tissues and/or processes should FDA consider in reviewing procedures that may have the ability to reduce infectivity of bovine neurological tissues and products containing bovine neurological tissues?

  11. Question 5 • What tests are available to ascertain changes in infectivity in products containing bovine neurological tissues as a result of processing?

  12. Question 6 • What level of reduction in infectivity is necessary to consider products containing bovine neurological tissues non-infective or "safe" for human use?
