What is the most common microorganism found in seafood?

The most common microorganisms found in seafood are bacteria, particularly species of Vibrio, such as Vibrio parahaemolyticus and Vibrio vulnificus. These bacteria are often present in marine environments and can cause foodborne illnesses if seafood is consumed raw or undercooked. Other microorganisms, including Salmonella and Listeria monocytogenes, can also be found in seafood, depending on handling and environmental conditions. Proper cooking and handling are essential to minimize the risk of infection.
