The UK is experiencing its worst bird flu outbreak, primarily affecting free-range poultry farms, with over half of the country's free-range turkey population lost or destroyed. Despite these losses, there will be no turkey shortage for Christmas. The British Poultry Council is working with the government to protect healthy birds and prevent the disease from spreading. The government is also compensating farmers for culled birds, preventing price increases. The outbreak, part of the largest avian flu epidemic in Europe and the US, is due to genetic mutations that make the virus more efficient and able to infect a wider range of species. The World Health Organization reassures that the overall public health risk from avian influenza to humans remains the same.
