A case of bird flu has been identified near Woodbridge – the fifth outbreak reported in Suffolk in a month.

A 3km protection zone and a 10km surveillance zone has been put in place around the infected premises, near Debach, to limit the risk of the disease spreading.

The zones were put in place by the Department for Environment, Food and Rural Affairs at 7pm on Sunday, according to a report on the government's website.

Suffolk Trading Standards has recently confirmed outbreaks of bird flu on farms in Elmswell, Gressingham, Redgrave and Market Weston since the end of February.

Protection zones were put in place around the farms and birds at the affected sites were culled.

Trading Standards officers had been going door to door in the 3km protection zone after the fourth case was identified in Market Weston earlier this month.

They have also warned that the risk of wild birds carrying flu remains very high and are now telling people who own birds to keep them inside.

Bird keepers within the protection zone must cleanse and disinfect clothing, footwear, vehicles and equipment before and after contact with poultry and captive birds – if practical, use disposable protective clothing and minimise direct and indirect contact between poultry and captive birds and wild birds, including making sure all feed and water is not accessible to wild birds.

In a post on Facebook Suffolk Trading Standards said: "If your birds aren’t housed you are putting them at huge risk and if they are housed they are still at high risk if you don’t practice good biosecurity."

In December, UK chief vet Christin Middlemiss said the department had taken "swift action" to limit the spread of the disease including housing measures.

She added: "However, we are seeing a growing number of bird flu cases both on commercial farms and in backyard birds right across the country.

"Many poultry keepers have excellent biosecurity standards but the number of cases we are seeing suggests that no enough is being done to keep bird flu out.

"Whether you keep just a few birds or thousands you must take action now to protect your birds from this highly infectious disease."
