Prevention Tips

Reduce your risk of vibriosis by following these tips:

  • Don’t eat raw or undercooked oysters or other shellfish. Cook them before eating.
  • Always wash your hands with soap and water after handing raw shellfish.
  • Avoid contaminating cooked shellfish with raw shellfish and its juices.
  • Stay out of brackish or salt water if you have a wound (including cuts and scrapes), or cover your wound with a waterproof bandage if there’s a possibility it could come into contact with brackish or salt water, raw seafood, or raw seafood juices. Brackish water is a mixture of fresh and sea water. It is often found where rivers meet the sea.
  • Wash wounds and cuts thoroughly with soap and water if they have been exposed to seawater or raw seafood or its juices.
  • If you develop a skin infection, tell your medical provider if your skin has come into contact with brackish or salt water, raw seafood, or raw seafood juices.

  • Wear protective gloves when handling raw seafood.
