What are foodborne trematodiases?

Foodborne trematodiases are caused by parasitic trematode worms. People become infected by eating raw or undercooked fish, crustaceans and vegetables that contain the larval worms.

Early and light infections may pass unnoticed, as they often cause little to no symptoms at all.

However, more severe infections can affect the bile ducts, gall bladder and lungs, causing symptoms ranging from general malaise to severe abdominal and chest pain, fever, inflammation, fibrosis, colic pain and jaundice.

~7,000 deaths are reported annually 200,000 cases are reported annually
