Parasites
Parasites are organisms that derive nourishment and protection from other living organisms known as hosts. Many of these organisms can be transmitted by water, soil, or person-to-person contact.
Parasites range in size from tiny, single-celled organisms to worms visible to the naked eye.
The most common foodborne parasites are protozoa, roundworms, and tapeworms. However, the food poisoning from parasites is rare in Ireland. The most common cause when it does happen is Toxoplasmosis caused by foodborne parasite Toxoplasma gondii
