Raw shrimp often contain a bacterium called Vibrio. Over 70 species exist, 12 of which are known to cause illness in humans (9, 10, 11, 12). A study in 299 raw shrimp samples determined that 55% contained potentially harmful Vibrio species responsible for conditions like gastritis, cholera, and infections (12). In addition, a study in farmed shrimp found 100 strains of Vibrio, many of which were resistant to antibiotic treatment (13). In a review of 10 seafood processing plants in Nigeria, 100% of shrimp harbored Bacillus bacteria, which is commonly associated with diarrhea and vomiting (14).
