Anemia may also be present. Illness can be prevented by sanitary handling of foods, avoidance of raw fruits and vegetables in areas where the protozoa are common, and proper sewage disposal. About parasites Organisms that depend on nutrients from a living host to complete their life cycle are called parasites. Trichinosis and Toxoplasmosis are two human diseases caused by parasites. The source of Trichinosis is undercooked pork or game infected by Trichinella spiralis larvae.
Thorough cooking kills the larvae.
Fecal waste from infected cats is the source of Toxoplasmosis. Because newborns are at greatest risk, pregnant women should wash hands thoroughly after petting cats and avoid changing cat litter boxes. All rights reserved.
