Infectivity in Bovine Tonsil

We were asked by the Food Standards Agency (FSA) to review preliminary results from a long-term study of experimental BSE in cattle.

This research is funded by the Food Standards Agency and is being carried out by researchers from the Veterinary Laboratory Agency. This research forms part of a large long-term experiment, which is ongoing. However, the Food Standards Agency and the researchers have released these preliminary results so that any appropriate public health action can be considered.

We have reviewed the results of this ongoing research and have prepared a summary of our advice. We make recommendations regarding further information required to conduct a risk assessment.

This statement (17 KB) has been released with the full agreement of both the Food Standards Agency and the researchers. A press release issued by the FSA on 17 October 2002 is also available.
