POSSIBLE BSE IN A 1990 UK GOAT SAMPLE

Scientists at the Veterinary Laboratories Agency have informed Defra
that a goat, confirmed as having scrapie in 1990, may have had BSE.

More sensitive testing methods have found the sample had traits similar
to samples from goats experimentally infected with BSE. Further tests
will now be carried out.

The VLA made the finding following the recent case of BSE in a goat from
France. The VLA had been checking whether methods developed to
discriminate between scrapie and BSE in sheep could also differentiate
these diseases in a goat.

The goat appears to have originated from premises in Scotland;
investigations have revealed that the original keeper is no longer in
business at these premises.

The single result, using just one test method, is insufficient to
confirm that the goat had BSE, and further rapid molecular methods to
discriminate BSE and scrapie cannot be applied because no frozen tissues
are available.

Researchers from the VLA have been asked to carry out tests to follow up
these initial findings. Further work will now need to be performed and
this will take 1-2 years, at the earliest, to complete.

Defra's Chief Veterinary Officer, Debby Reynolds, said: "It is important
to put this initial finding into context. It dates back to 1990 which
was at the height of the BSE outbreak in cattle and before the
reinforced feed ban was introduced in 1996. This means that there is a
distinct possibility that the animal, if infected with BSE, was exposed
to contaminated feed.

"In light of the recent case of BSE in a goat from France, the European
Commission says it is important to perform increased surveillance on
goats on a European-wide basis to establish the current incidence of
TSEs in the goat population. In line with this, Defra will be stepping
up its TSE surveillance programme for goats."

Defra will be asking the Spongiform Encephalopathy Advisory Committee
for their comments on this finding at their meeting on the 3 March.

Possible case of BSE agent in a UK goat that died in 1990

Editorial team (eurosurveillance.weekly@hpa.org.uk
), Eurosurveillance editorial
office

Following the confirmation in January 2005 of a French goat having a
transmissible spongiform encephalopathy indistinguishable from bovine
spongiform encephalopathy (BSE) [1,2], the United Kingdom Department for
Environment, Food and Rural Affairs has announced that a goat in the
United Kingdom (UK), confirmed as having scrapie in 1990, may have had
BSE [3].

More sensitive testing methods have found that a sample from the goat
had traits similar to goats experimentally infected with BSE. However,
this single result is insufficient to confirm that the goat did have
BSE. Further testing, including bioassays, which take around 2 years to
complete, are now necessary.

The year 1990 was the height of the BSE outbreak in cattle in the UK. A
ban on feeding meat and bone meal to ruminants was introduced across the
European Union in 1994. The TSE surveillance programme of sheep and
goats will be increased in the United Kingdom, in line with the
announced increases across the European Union.

The European Community TSE Reference Laboratory at the Veterinary
Laboratories Agency
(http://www.defra.gov.uk/corporate/vla/science/science-tse-rl-intro.htm)
will complete the testing.
