What is a common foodborne source associated with Vibrio cholerae outbreaks in endemic regions?

• A. Contaminated water or seafood, especially raw or undercooked shellfish.
• B. Pasteurized dairy products.
• C. Undercooked poultry.
• D. Leafy greens.

Answer: (C)

Vibrio cholerae outbreaks in endemic regions are driven mainly by ingestion of contaminated water and seafood, particularly raw or undercooked shellfish. The bacteria thrive in contaminated aquatic environments, and shellfish like oysters can accumulate high bacterial loads, turning their consumption into a common route of infection. This is why contaminated water or seafood is the best described source. Pasteurized dairy products are generally safe because heat treatment kills the organism; undercooked poultry is more associated with pathogens like Campylobacter or Salmonella, not Vibrio cholerae; leafy greens can carry other bacteria but are not the classic cholera vehicle.
