At least two foxes have died so far after being infected by the bird flu virus, the Belgian Nature and Forest Agency found after examining 25 fox carcasses.
According to the agency, the animals became ill after eating sick or dead birds.
The bird flu virus is still raging on the Coast. Further research should now show whether foxes also spread the virus among other mammals.
Anyone who sees sick or dead birds or foxes should report them on the influenza line for dead or sick birds, or contact the Ostend Bird and Wild Animal Rehabilitation Center for dead foxes.
