A Vibrio death is being investigated by public health officials in Escambia County, Florida, according to the Florida Department of Health in that county. Vibrio vulnificus is a bacterium that lives in warm, brackish seawater and it grows faster in the warmer summer months. Shellfish, including oysters, consume the pathogen as they feed on plankton, and it concentrates in the flesh. Anyone who eats a contaminated raw or undercooked oysters can get sick. And anyone with cuts, scratches, or open wounds can be exposed to the pathogen through direct contact with seawater or estuarine water. About 80,000 people are sickened with vibriosis every year, and about 100 people die. While most people who contract this infection only have a mild illness, people in certain populations can … [Read more...]

How Do You Know If You Have a Vibrio Parahaemolyticus Infection?
How do you know if you have a Vibrio parahaemolyticus infection? This illness is caused by a type of bacteria that grows in marine water and can grow in shellfish. The pathogen causes an illness called vibriosis. Vibrio bacteria are found naturally in marine coastal waters, in saltwater, and in rivers and streams where freshwater meets saltwater. It is usually present in levels that are low enough to cause no problems, but it grows and multiples rapidly when water temperatures are high. Most vibrio illnesses and outbreaks occur in the summer months. Most cases of vibriosis are caused by eating raw and undercooked shellfish. Even fully cooked seafood can be recontaminated if rinsed with seawater after cooking. Other issues that can cause rapid bacteria growth include not keeping … [Read more...]

Avoid Making and Serving These Potentially Dangerous Holiday Foods
Every year people are sickened by certain types of foods. Avoid making and serving these potentially dangerous holiday foods this season. Some are inherently dangerous, and others are easily contaminated with dangerous bacteria. The potentially harmful foods include cannibal sandwiches, raw cookie dough, eggnog, unpasteurized cider, and raw oysters. Cannibal sandwiches are sandwiches made with raw ground beef. They are a specialty in some areas of the Midwest United States. In 2013, an E. coli O157:H7 outbreak in Wisconsin was associated with the seasonal consumption of these sandwiches. Raw ground beef is inherently risky, because cows carry pathogenic STEC bacteria in their guts. When the cows are slaughtered, the bacteria are released and can contaminate the beef. When this beef … [Read more...]
