Answer

Avoid eating raw or undercooked seafood. Contaminated seafood cannot be distinguished by smell or taste. This is especially important for individuals with conditions that predispose to invasive Vibrio infections. [50]

  • Fry, bake, steam, or boil oysters, clams, and mussels 4-9 minutes or until plump.

  • Boil shrimp or crab until shells turn pink and the meat is cooked in the middle.

  • Fish is cooked until the thickest part is opaque.

Avoid exposure to seawater in summer months or along the coastal regions in the southeastern United States.

Promptly seek medical attention if fever, nausea, abdominal cramps, diarrhea, myalgia, or severe pain in the lower extremities develops.

Studies of V vulnificus bacteriophage SSP002 have demonstrated its protective efficacy in infected mouse models and its potential use as a biocontrol agent against V vulnificus in the food industry. [51]

High hydrostatic pressure (HPP), a nonthermal process, has been shown to be effective in inactivating V vulnificus and V parahaemolyticus in oysters without changes in original nutrient, flavor, or appearance. However, because of the high cost of HPP, this process may not be affordable by most oyster producers. [52]
