An outbreak of bird flu has been declared at a property near Wells.
The Department of Environment, Food and Rural Affairs confirmed avian influenza H5N1 in birds at the premises on Sunday night and further testing is currently underway to determine the pathogenicity of the strain.
There are now 3km and 10km temporary control zones in place around the site.
Although avian influenza is potentially deadly to birds, UK food and health agencies advise that the risk to public health from the virus is very low and that it poses a very low food safety risk for consumers.
The news comes after a national bird flu prevention zone was declared earlier this month in order to prevent the spread of the disease which damaged East Anglia's poultry industry last winter.
It has now become a legal requirement for all bird keepers across the country to follow strict biosecurity measures to help protect their flocks.
