Which food practice increases the risk of Vibrio infection?

• A. Eating raw shellfish, especially oysters
• B. Drinking water with chlorine
• C. Cooking shellfish thoroughly
• D. Eating canned vegetables

Answer: (A)

Vibrio bacteria are found in warm coastal waters and readily contaminate raw shellfish like oysters. Eating them raw lets the bacteria into the body and can cause infection, especially in people with certain health conditions. Thoroughly cooking shellfish kills Vibrio, making cooked shellfish much safer to eat. While chlorinated drinking water helps reduce many waterborne pathogens, it doesn’t address shellfish contamination, and canned vegetables have been heat-processed to destroy bacteria, so they’re unlikely sources of Vibrio infection.
