Tapeworm Infection from Fruit: Risks, Causes, and Prevention

While tapeworm infections are most commonly associated with consuming raw or undercooked meat, fish, or poultry, it is possible—though rare—to contract a tapeworm from contaminated fruit. Tapeworms are flat, segmented parasites that can grow several feet long in the human intestine, causing symptoms such as abdominal pain, diarrhea, weight loss, and fatigue. In severe cases, they may lead to intestinal obstruction or malnutrition.

How Fruit Becomes Contaminated

Fruit can harbor tapeworm eggs if it is grown in soil fertilized with human feces or washed with contaminated water. Additionally, fruit flies may mechanically transfer eggs onto the surface of produce. When such fruit is eaten raw, the eggs can be ingested and hatch in the digestive tract.

Reducing Your Risk

To minimize the chance of tapeworm infection from fruit, follow these precautions:

• Wash all fruits thoroughly under running water before eating.
• Peel fruits whenever possible.
• Cook fruits thoroughly if you are in an area with questionable sanitation.
• Avoid fruits known to be grown in soil fertilized with human waste.
• Avoid fruits washed with untreated or potentially contaminated water.

When to See a Doctor

If you experience persistent abdominal pain, unexplained weight loss, chronic diarrhea, or fatigue, consult a healthcare provider. A stool test can detect tapeworm eggs or segments, and effective prescription medications are available to eliminate the infection.
