What is Vibrio vulnificus food poisoning ?
Vibrio vulnificus food poisoning is caused by Vibrio vulnificus, a bacterium that lives in warm seawater. The condition is rare.
What causes Vibrio vulnificus food poisoning ?
Vibrio vulnificus food poisoning occurs when you eat seafood infected with the bacteria or you have an open wound that is exposed to them. The bacteria are frequently found in oysters and other shellfish in warm coastal waters during the summer months. People with weak immune systems, especially those with long-term (chronic) liver disease, are at greater risk for developing the condition than others.
What are the symptoms ?
In healthy people, Vibrio vulnificus food poisoning can cause vomiting, diarrhea, and abdominal pain. In people who have weak immune systems, the bacteria can infect the bloodstream, causing a severe and life-threatening illness. Symptoms include fever and chills, decreased blood pressure (septic shock), and blistering skin wounds. The infection is especially dangerous to people with long-term (chronic) liver disease.
If an open wound is exposed to the bacteria (such as from warm seawater), it may result in the skin breaking open and sores developing. People with weak immune systems are at risk for the bacteria moving into the bloodstream.
How is Vibrio vulnificus food poisoning diagnosed ?
Vibrio vulnificus food poisoning is diagnosed based on a medical history and a physical exam. Your health professional will ask you questions about your symptoms, foods you have recently eaten, and your work and home environments. If you have eaten raw seafood, especially oysters, your health professional may do a stool, wound, or blood culture.
How is it treated ?
You treat Vibrio vulnificus food poisoning by managing any complications until it passes. Dehydration caused by diarrhea and vomiting is the most common complication. In people with weak immune systems, or in people with severe symptoms, antibiotics may be used.
To prevent dehydration, take frequent sips of a rehydration drink (such as Lytren, Rehydralyte, or Pedialyte). Try to drink a cup of water or rehydration drink for each large, loose stool you have. Sports drinks, soda pop, and fruit juice contain too much sugar and not enough of the important electrolytes that are lost through diarrhea and should only be taken alternately with a rehydration drink.
Try to stick to your normal diet as much as possible. Eating your usual diet will help you to get enough nutrition. Doctors believe that eating a normal diet will also help you feel better faster. But try to avoid foods that are high in fat and sugar. Also avoid spicy foods, alcohol, and coffee for 2 days after all symptoms have disappeared.
How can I prevent Vibrio vulnificus food poisoning ?
The best way to prevent this type of food poisoning is to not eat raw oysters or other raw shellfish and to cook all shellfish (oysters, clams, mussels) thoroughly.
Boil shucked oysters at least 3 minutes, or fry them in oil at least 10 minutes at 375 F. For shellfish in the shell, either :
Boil until the shells open and continue boiling for 5 more minutes, or
Steam until the shells open and then continue cooking for 9 more minutes.
Do not eat those shellfish that do not open during cooking.
You should also :
* Avoid cross-contamination of cooked seafood and other foods with raw seafood and juices from raw seafood. Don't prepare them in the same place; and don't use the same cutting board when preparing them.
* Eat shellfish immediately after cooking, and refrigerate leftovers.
* Avoid exposing open wounds or broken skin to warm saltwater or brackish water or to raw shellfish harvested from such waters.
* Wear protective clothing, such as gloves, when handling raw shellfish.
