Hannah Pettifer reports on the dead swans discovered in the River Stour in Suffolk
Thousands of birds are being culled after three more cases of bird flu were confirmed in East Anglia.
DEFRA says that avian influenza has now been found in poultry at a second premises near Bury St Edmunds in Suffolk and two different premises near Attleborough in Norfolk.
A 3km protection zone and 10km surveillance zone have now been put in place around each of the outbreaks.
It comes after a number of swans were also found dead in the River Stour at Brundon mill near Sudbury in Suffolk.
Ian Hepburn walks his dog around Sudbury water meadows every week and found six dead swans on his latest walk.
"The last thing you expect to see is carcasses of these wonderful creatures lying here and you wonder where it's going to end" he told ITV News Anglia.
"I rang the rangers and they told me they retrieved other birds earlier in the week and you wonder where it's going to end, is this hideous disease going to wipe out the entire population?"
Defra has confirmed it's carrying out tests to determine the cause of death but bird flu is suspected.
The UK Health Security Agency says that the risk to the general public's health was "very low", as it is primarily a disease that affects birds.
The Food Standards Agency says that the outbreaks pose a "very low food safety risk", as long as poultry and poultry products are cooked properly.
The public are being told that if you find:
one or more dead bird of prey or owl
3 or more dead gulls or wild waterfowl (swans, geese and ducks)
5 or more dead birds of any species
You should call the Defra helpline (03459 33 55 77)
