Question

Which of the following spreads through food contamination?

• A. Taenia
• B. Schistosoma
• C. Ascaris
• D. Fasciola

Answer 1

The correct option is C Ascaris

• Mode of transmission of Taenia. Eggs of T. saginata passed in the faeces of an infected person are only infectious to cattle. Humans are infected by ingestion of raw or undercooked beef infected with Cysticercus bovis, the larval stage of T. saginata.
• Water has a key role in schistosomiasis transmission and spread.
• Ascariasis is transmitted indirectly in most cases by an uninfected individual ingesting contaminated food or water that contain the Ascaris eggs deposited by infected humans in their feces into the environment.
• Fasciola: Transmission occurs through the ingestion of raw, fresh-water vegetation on which the flukes in their metacercariae form are encysted.

So, the correct answer is 'Ascaris'.
