The UK is experiencing its worst bird flu outbreak in history, with the disease affecting around half of the free-range turkeys and geese raised for Christmas. According to Richard Griffiths, CEO of the British Poultry Council, the outbreak has resulted in the death or culling of approximately 600,000 free-range birds and 1.1 million Christmas turkeys. The situation has led to avian flu controls being implemented on 36% of UK farms. The potential impact on prices remains uncertain.
