Over the next few months, many more foxes in Western Sweden will be examined in order to map the spread of the parasite.
The eggs of the tapeworm can end up on berries and mushroom in the woods via the fox's faeces. The parasite is relatively harmless to foxes, cats and dogs. It does not usually spread to humans, but if it does it could cause serious illness, as it is hard to treat and discover. The advice from the veterinary institute is to wash your hands after touching pets that have been out in the affected areas, and to cook mushrooms and wash berries picked in those areas.
