Quick answer

What is Tapeworm infection?

A tapeworm infection is an intestinal infection caused by a flat, ribbon-like parasitic worm. People usually catch it by eating raw or undercooked meat (beef or pork) or fish that contains tapeworm larvae, which then develop into an adult worm in the gut.

  • How it is treated: A tapeworm infection of the gut is treated with a single dose (or short course) of anti-parasitic medicine, which kills the worm so it passes out of the body; this is usually very effective.
  • Self-care: Cook meat and fish thoroughly, practise good food and hand hygiene, use safe food and water when travelling, and complete any prescribed treatment.
  • When to seek help: See a GP if you notice worm segments in your stool, or have persistent tummy symptoms after possible exposure (such as undercooked meat or relevant travel), so it can be tested for and treated.

What it is

A tapeworm infection is an intestinal infection caused by a flat, ribbon-like parasitic worm. People usually catch it by eating raw or undercooked meat (beef or pork) or fish that contains tapeworm larvae, which then develop into an adult worm in the gut. Tapeworm infection is uncommon in countries with good food-safety and sanitation, and in the UK it is mainly seen in travellers or from imported or undercooked food. Many people have no symptoms; when symptoms occur they can include mild tummy discomfort, nausea, changes in appetite, tiredness, and sometimes noticing segments of the worm or eggs in the stool. Most tapeworm infections of the gut are not serious and are easily treated. A different, more serious situation can occur with certain tapeworms when their larvae form cysts in body tissues (such as the brain or liver) — this is a separate, more complex condition needing specialist care.

How it is treated

A tapeworm infection of the gut is treated with a single dose (or short course) of anti-parasitic medicine, which kills the worm so it passes out of the body; this is usually very effective. Good hygiene helps prevent it spreading. The diagnosis is confirmed by examining stool samples for eggs or worm segments. Preventing tapeworm infection centres on food safety: cooking meat and fish thoroughly, freezing where appropriate, good hand and food hygiene, and safe food and water practices when travelling in areas where it is more common. The more serious situation where tapeworm larvae form cysts in the body's tissues is diagnosed and managed by specialists, and is quite different from a simple gut infection. The reassuring message is that a tapeworm infection of the intestine is usually not serious and is easily treated with anti-parasitic medicine and good hygiene.
