🦠 What are foodborne parasites?

Parasites are small organisms that live in or on a host (like humans) and depend on it to survive. They can enter the body through contaminated or undercooked food.

Some well-known infections include:

• Anisakiasis (linked to raw fish)
• Taeniasis (tapeworms from meat)
• Toxoplasmosis
