Prevention of Vibrio vulnificus

Prevention of Vibrio vulnificus:

Vibrio vulnificus (General): DBMD (Excerpt)

Although oysters can be harvested legally only from waters free from fecal contamination, even legally harvested oysters can be contaminated with V. vulnificus because the bacterium is naturally present in marine environments. V. vulnificus does not alter the appearance, taste, or odor of oysters. Timely, voluntary reporting of V. vulnificus infections to CDC and to regional offices of the Food and Drug Administration (FDA) will help collaborative efforts to improve investigation of these infections. Regional FDA specialists with expert knowledge about shellfish assist state officials with tracebacks of shellfish and, when notified rapidly about cases, are able to sample harvest waters to discover possible sources of infection and to close oyster beds when problems are identified. Ongoing research may help us to predict environmental or other factors that increase the chance that oysters carry pathogens. (Source: excerpt from Vibrio vulnificus (General): DBMD)

Some tips for preventing V. vulnificus infections, particularly among immunocompromised patients, including those with underlying liver disease:

  • Do not eat raw oysters or other raw shellfish.
  • Cook shellfish (oysters, clams, mussels) thoroughly:
  • For shellfish in the shell, either a) boil until the shells open and continue boiling for 5 more minutes, or b) steam until the shells open and then continue cooking for 9 more minutes. Do not eat those shellfish that do not open during cooking. Boil shucked oysters at least 3 minutes, or fry them in oil at least 10 minutes at 375F.
  • Avoid cross-contamination of cooked seafood and other foods with raw seafood and juices from raw seafood.
  • Eat shellfish promptly after cooking and refrigerate leftovers.
  • Avoid exposure of open wounds or broken skin to warm salt or brackish water, or to raw shellfish harvested from such waters.
  • Wear protective clothing (e.g., gloves) when handling raw shellfish.
