Causes of a tapeworm infection
In the UK, a tapeworm infection usually occurs when you eat raw contaminated pork, beef or freshwater fish. Not all tapeworms are acquired in the same way.
Diagnosing a tapeworm infection
If you think you have a tapeworm infection, speak to your GP so they can give you a diagnosis.
Treating a tapeworm infection
Adult tapeworm infections are treated with medication. It is more complicated to treat infection with tapeworm larvae.

The best ways to prevent tapeworm infections are to prepare food properly and look after your personal hygiene, particularly around animals.
