Prevention & Control

Angiostrongylus cantonensis

Prevention of A. cantonensis infections involves educating persons residing in or traveling to areas where the parasite is found about not ingesting raw or undercooked snails and slugs, freshwater shrimp, land crabs, frogs, and monitor lizards, or potentially contaminated vegetables, or vegetable juice. Removing snails, slugs, and rats found near houses and gardens should also help reduce risk. Thoroughly washing hands and utensils after preparing raw snails or slugs is also recommended. Vegetables should be thoroughly washed if eaten raw.
