A suspected case of bird flu has been identified in chickens at a poultry farm in Fife.
Birds at the site will now be culled and a 1km control zone has been set up around the premises in Dunfermline.
The Scottish government confirmed its vets had found a strain of avian flu (H5) at the farm.
Initial tests have suggested it is a “low pathogenic strain” but poultry farmers across Scotland are being urged to be vigilant.
Health officials said the risk to human health was thought to be “very low”.
There have been a number of recent cases of avian influenza across continental Europe in recent months including three cases in other parts of the UK in 2015.
Within the control zone a range of different controls are in place which include restrictions of the movement of poultry, carcasses, eggs, used poultry litter and manure and restrictions on bird gatherings.
Scotland’s Chief Veterinary Officer, Sheila Voas, said: “We have taken immediate action to contain this case as part of our robust procedures for dealing swiftly with avian flu.
“Evidence suggests this is a low severity form of the virus however we are taking action to ensure that the disease does not spread or develop into a more severe form.
“I would urge poultry keepers in the surrounding area to be vigilant for any signs of disease and to ensure they are maintaining good biosecurity on their premises.”
The Scottish government’s Rural Affairs Secretary, Richard Lochhead, said: “Livestock owners and the general public should be assured that we are doing everything we can to control and prevent the spread of the disease.
“Any poultry producers who are concerned should immediately seek veterinary advice.”
Dr Jim McMenamin, consultant epidemiologist and respiratory infection lead for Health Protection Scotland, said: “Based on what we know about this strain of avian influenza and the actions that have been taken, the risk to human health in this case is considered very low.
“Health Protection Scotland continues to work closely with Animal Health throughout this investigation”
Rita Botto, head veterinarian of Food Standard Scotland said: “On the basis of current scientific evidence, Food Standards Scotland’s advice is that bird flu does not pose a food safety risk for UK consumers.”
