Ingestion of food contaminated with the eggs

Fertilized Ascaris eggs released in feces may contaminate food or water, which is then consumed. Ascaris does not attach to the intestine but maintains its position by mobility. The worm may become hyper-motile (e.g., during febrile periods, anesthetic use, or antibiotic use) and may migrate into the appendix or bile duct.
