Vibrio parahaemolyticus is one of several marine microorganisms that are dangerous to human health. It was first detected by food poisoning in hot days in Japan. As the international trade of seafood expands, the poisoning events in the European countries began to be seen in the 1970 years. Researches have revealed that vibrio parahaemolyticus bacteria are found in sea water, seabed deposits, marine animals and plankton. In these studies, the enteropathogenic species of the bacteria were called vibrio parahaemolyticus and the non-pathogenic species were called vibrio alginolyticus.

Vibrio parahaemolyticus bacteria are mostly microorganisms that come to life on the coast and river mouths. There are not many fish caught in the high seas. These bacteria are found in the coastal waters of average 20 degrees of the sea. They reproduce quickly on seafood. Since the waters in the river mouths are very rich in organic matter, these bacteria are also found here.

Vibrio parahaemolyticus bacteria are gram negative and motile microorganisms. It is not possible to reproduce below 10. They die after a while in this cold. On the other hand, it maintains its vitality in frozen food products. Therefore, when frozen seafood thaws during transportation and freezes again, this causes contamination. Under optimal conditions, the generation times of vibrio parahaemolyticus bacteria are average 12 minutes.

In advanced laboratories, studies on the determination of vibrio parahaemolyticus are carried out within the scope of microbiological analyzes. These studies are based on standards published by domestic and foreign organizations. The standards considered in this regard are:

• ISO / TS 21872-1 Microbiology of food and animal feeds - Potentially enteropathogenic vibrio species - Part 1: Identification of vibrio parahaemolyticus and vibrio cholerae bacteria
• ISO / TS 21872-2 Microbiology of food and animal feed - Potentially enteropathogenic vibrio species - Part 2: Detection of bacterial species other than vibrio parahaemolyticus and vibrio cholerae
