Statement
- 20th March 1996
The Spongiform Encephalopathy Advisory Committee have considered
10 cases of Creutzfeldt-Jakob Disease (CJD) which have occurred
in people aged under 42 and which have recently been identified
by the CJD Surveillance Unit, Edinburgh. The Committee have concluded
that the Unit has identified a previously unrecognised and consistent
disease pattern. A review of patients' medical histories, genetic
analysis to date and consideration of other possible causes, such
as increased ascertainment, have failed to explain these cases adequately.
Although there is no direct evidence of a link, on current data
and in the absence of any credible alternative the most likely explanation
at present is that these cases are linked to exposure to BSE before
the introduction of the Specified Bovine Offal (SBO) ban in 1989.
This is a cause for great concern.
CJD remains a rare disease and it is too early to predict how many
further cases, if any, there will be of this new form. Continued
surveillance is of the utmost importance and the Committee are actively
seeking further data from both the UK and abroad to help assess
the full significance of the Unit's findings.
The Committee emphasised that it is imperative that current measures
to protect the public health are properly enforced and recommend
constant supervision to ensure the complete removal of spinal cord.
The Committee also recommended:
- that carcasses from cattle aged over 30 months must be deboned
in licensed plants supervised by the Meat Hygiene Service and
the trimmings must be classified as SBOs;
- a prohibition on the use of mammalian meat and bonemeal (MBM)
in feed for all farm animals;
- that the Health and Safety Executive (HSE) and the Advisory
Committee on Dangerous Pathogens (ACDP), in consultation with
SEAC, should urgently review their advice in the light of these
findings;
- that the Committee urgently consider what further research is
necessary.
The Committee does not consider that these findings lead it to
revise its advice on the safety of milk. If the recommendations
set out above are carried out the Committee concluded that the risk
from eating beef is now likely to be extremely small.
