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?
What tests are available to ascertain changes in infectivity in products containing bovine neurological tissues as a result of processing?
What level of reduction in infectivity is necessary to consider products containing bovine neurological tissues non-infective or "safe" for human use?
