WHO Recommendations

· To protect human health, WHO has also recommended the following:

- No part or product of any animal which has shown signs of a TSE should enter any (human or animal) food chain;

- Countries should not permit tissues that are likely to contain the BSE agent to enter any (human or animal) food chain;

- All countries should ban the use of ruminant tissues in ruminant feed.

· Human and veterinary vaccines prepared from bovine materials may carry the risk of transmission of animal TSE agents. The pharmaceutical industry should ideally avoid the use of bovine materials and materials from other animal species in which TSEs naturally occur. If absolutely necessary, bovine materials should be obtained from countries which have a surveillance system for BSE in place and which report either zero or only sporadic cases of BSE. These precautions apply to the manufacture of cosmetics as well.

· In 1999, a review was conducted of the known information about a number of animal TSEs to try to proactively determine if there are any new TSE threats. Their principle recommendations were to eradicate BSE and to find out if BSE has infected sheep populations. The recommendations are available at under the heading ‘TSE’.

· WHO published guidelines for infection control of TSEs in 2000. The full text is available at under the heading ‘TSE’.
