The primary vector for Vibrio gastroenteritis is typically raw shellfish. This bacterium is commonly associated with marine environments, and it can be found in warm coastal waters, where shellfish, particularly oysters, thrive. When consumed raw or undercooked, these shellfish can introduce the Vibrio bacteria into the human digestive system, leading to gastrointestinal illness.

While contaminated water can also play a role in Vibrio infections, the most direct and significant risk factor is the consumption of raw shellfish. Understanding the sources of Vibrio is crucial for food safety and public health, especially for individuals who enjoy seafood or live in regions where seafood consumption is common.
