New rules for bird keepers to stop spread of avian flu | Updated: 17:14, 18 December 2020 New rules have been introduced across the UK to help prevent the spread of bird flu, Warwickshire County Council Trading Standards Animal Health team have announced. Bird keepers are being reminded to keep their birds indoors and follow strict biosecurity measures to help limit the spread of avian flu. Last week the Herald revealed that two swans found dead on the River Avon in Stratford had tested positive for bird flu, with a number of other cases also being reported in birds across the country. New rules have now come into effect for those who keep birds (including businesses/farmers and those who keep birds as pets or as a hobby).
