Which of the following is an appropriate measure to prevent Vibrio vulnificus infection?

• A. Cook shellfish thoroughly; Avoid raw shellfish; Keep wounds clean and covered
• B. Eat raw shellfish to build immunity
• C. Use antibiotics after every seafood meal
• D. Do nothing; Vibrio is not a concern

Answer: (A)

Prevention focuses on eliminating the bacteria from the primary routes of exposure: ingestion and wound contact. Cooking shellfish thoroughly destroys Vibrio vulnificus, so thoroughly heated shellfish is much less likely to cause infection. Avoiding raw or undercooked shellfish removes the most common source of illness. Protecting any open wounds from contact with seawater or seafood handling by keeping them clean and covered helps prevent bacteria from entering through broken skin. Together, these practices reduce both ingestion- and exposure-related risks.

Eating raw shellfish to build immunity isn’t protective and can cause serious illness. Using antibiotics after every seafood meal is inappropriate and can lead to resistance or side effects. Doing nothing ignores real infection risks posed by Vibrio vulnificus.
