A spokesman said: ‘As part of our robust action in response to the confirmed case of avian flu, we are considering a range of measures including destroying a shipment of eggs sent to a separate farm for hatching earlier in November. ‘This is in line with our tried and tested procedures for dealing with avian flu outbreaks.’ Cherry Valley admitted the move • but insisted: ‘As the World Health Organisation, the Minister, the Food Standards Agency, Public Health England and others have made clear, there is absolutely no risk to humans and people should continue to eat all forms of poultry. ‘Any eggs that are destroyed are done so to protect the integrity of the supply chain and ensure that the disease does not affect more birds.’  Dr Colin Butter, head of avian viral immunology at The Pirbright Institute for animal health, said: ‘It’s certainly possible that eggs from an infected flock could carry influenza on the ir surface.’ He added: ‘In chickens you would know very fast because they die. With highly pathogenic bird flu, which this is, the can die within a couple of days, so you know very fast that you have a problem in the flock. ‘However, with some water fowl such as ducks, the symptoms of influenza can be much less severe, so farmers have to be on a very sharp lookout.’ But he added: ‘There’s all evidence to suggest this farm picked it up extremely quickly... [And] I’m quite sure the scientists from Defra have this question in hand.’  A Defra spokesman said: ‘The advice from the Chief Medical Officer and Public Health England remains that the risk to public health is very low. The Food Standards Agency have said there is no food safety risk for consumers.’
