A cull of 27,000 chickens has been completed after cases of bird flu were detected at a poultry farm.
The premises near Eye are now being cleaned and disinfected by the Animal and Plant Health Agency.
Officials from the Department for Environment, Food and Rural Affairs (Defra) have found no evidence of bird flu at nearby farms.
An investigation is continuing to find the source of the outbreak and the risk of further spread.
Public Health England previously said the risk to the public was very low, while the Food Standards Agency said there was no food safety risk as long as poultry products were thoroughly cooked.
The strain at the commercial farm at Athelington, confirmed on 11 December, has been identified as “low pathogenic avian flu” (LPAI).
Highly pathogenic avian influenza (HPAI) is the more serious type of the disease which can prove fatal to birds.
LPAI is usually less serious but can cause mild breathing problems in poultry, Defra said.
The British Poultry Council said the Christmas turkey market was “unaffected” by the case.
In 2017, some 23,000 chickens were destroyed at Bridge Farm in Redgrave on the Suffolk/Norfolk border after the H5N8 avian influenza virus was found.
In June that year the same strain was identified in about 35 chickens and geese at a farm near Diss in Norfolk.
