Echinostomiasis is a major food-borne intestinal trematodiasis. Although usually asymptomatic, depending on the parasite load, different clinical symptoms can be presented. Light infections can cause anemia, headache, gastric pain, and loose stools. Heavy infections can cause abdominal pain, emaciation, weakness, anemia, profuse watery diarrhea, hemorrhage, edema, and anorexia (Graczyk and Fried, 1998)
