EU experts to discuss Avian influenza measures

Top of the agenda at a meeting of EU veterinary officials in Brussels today will be the fear that avian flu may spread to Europe, following cases in Russia and the Far East.

Some countries have already moved all poultry indoors in a preventative measure to reduce the risk of spreading the disease, a move adopted by the Dutch, but one which is thought unlikely to find favour with other European countries.

The European Commission are seeking opinions from veterinary experts on the possible vectors for the disease, such as migrating birds.

Health officials are concerned that the outbreak of avian flu among domestic flocks has already spread to humans in the areas affected, killing around 50 people in the Far East and Russia.

British veterinarians have already warned that there must be increased vigilance for the disease among birds, but are unlikely to recommend bringing free-range flocks indoors.

The last outbreak in Europe was in the Netherlands in 2003. The outbreak in the Netherlands led to the destruction of around 30 million birds and cost an estimated €150 million.

Avian influenza is a virulent and highly contagious viral disease which occurs in poultry and other birds.

First identified in Italy in the early 1900s, various strains of the virus are known, and in the highly pathogenic strains there is an almost 100% fatality rate.

Wild birds are often carriers of the low pathogenic strains of the virus without showing any symptoms, and contact of domestic flocks with wild migratory birds has been at the origin of many epidemics in poultry.

The virus can occasionally spread to humans and other animals, usually following direct contact with infected birds.
