What illness can be prevented by purchasing from approved suppliers?

The correct response highlights the importance of sourcing food from approved suppliers to prevent specific foodborne illnesses. Vibrio vulnificus, which can cause serious infections leading to primary septicemia and gastroenteritis, typically originates from raw or undercooked seafood, particularly oysters. Purchasing seafood from approved suppliers ensures that these products have been handled, stored, and processed under strict safety regulations that minimize the risk of contamination with harmful bacteria like Vibrio vulnificus.

Approved suppliers are regularly inspected and must comply with health and safety standards that help to prevent foodborne pathogens from entering the food supply. This preventive measure is critical in safeguarding public health, especially for individuals who are more susceptible to severe reactions from such bacteria, such as those with compromised immune systems.

Other options involve different pathogens that can also lead to foodborne illnesses, but sourcing from approved suppliers has a particularly critical impact on the safety of seafood products concerning Vibrio vulnificus.
