Keepers are being reminded that it is illegal to feed catering waste of any description or domestic food waste to farm animals in the UK, including pigs kept as pets, as some of the outbreaks of African swine fever in Europe have been attributed to wild boar or domestic pigs consuming contaminated pork or pork products. This includes food from vegetarian kitchens, as there is still a risk of cross contamination in products of animal origin such as milk.
