3 foods that are the most common causes of flesh eating bacteria

The rare bacterial infection 'Necrotizing Fasciitis' develops from flesh-eating bacteria which destroys human skin tissue, fat layers and muscle tissue coverings. The bacteria spreads quickly through the body, which results in fatal consequences when medical treatment does not start immediately. People become infected through contact with particular foods that contain dangerous bacteria. People who want to protect themselves from flesh-eating bacterial infections, need to understand which foods commonly transmit these dangerous pathogens. Here are 3 foods that are the most common causes of flesh eating bacteria....

Raw or undercooked oysters together with other shellfish, is one of the primary sources that leads to flesh-eating bacterial infections. The bacterium Vibrio vulnificus exists naturally in warm coastal waters, and can be found in raw or undercooked oysters and shellfish. The shellfish obtain these bacteria through their water filtration process, which leads to their accumulation inside their shell structures. People who consume Vibrio vulnificus contaminated raw oysters face a high risk of developing severe infections, which become deadly for those with compromised immune systems or liver disease.

The bacteria can enter human bodies through two routes, when people consume raw shellfish, or when they touch their skin while handling these foods. The infection produces vomiting and diarrhea, especially in summer months, because the bacteria multiply better in water at higher temperatures.

The bacteria that causes Necrotizing Fasciitis exist in undercooked or contaminated meat products, including poultry, beef and pork. Group A Streptococcus (GAS) bacteria which cause flesh-eating infections, can enter meat products during processing or handling operations. The bacteria which survives undercooked meat conditions, can enter human bodies through eating the meat or by penetrating through open wounds.

The storage and handling of meats without proper care, creates an environment where bacterial growth becomes more likely. People who consume these foods or touch raw meat juices near their skin wounds, become vulnerable to infection. The prevention of bacterial infections requires proper meat cooking temperatures, separate storage of raw meat from other foods and strict kitchen hygiene practices, to stop cross-contamination.

The flesh-eating bacteria found in crabs, shrimp and fish can be transmitted through seafood that comes from polluted waters and improper refrigeration methods. The dangerous Vibrio vulnificus and other Vibrio species thrive in warm brackish waters, by attaching themselves to seafood shells and surfaces. Consuming raw seafood or seafood that has been left at room temperature for extended periods, creates a high risk of developing dangerous infections.

People who handle seafood need to verify its freshness while maintaining proper storage temperatures, and complete thorough cooking of all seafood products. People with compromised immune systems should completely avoid eating raw seafood, because they face elevated dangers of developing severe infections. The practice of hand washing and tool sanitising after seafood contact, helps minimise the chance of food contamination.

The consumption of oysters, shellfish and certain types of meat requires following safety guidelines because these foods can harbor flesh-eating bacteria. You should purchase seafood and meats from authorised suppliers, who maintain rigorous safety protocols. Check the origin of your oysters from approved waters, and verify their shells remain closed while maintaining a fresh smell. The most effective method to minimise risk involves cooking shellfish and meats until they reach their recommended internal temperatures (oysters need to reach 145°F or 63°C). People who have weakened immune systems, liver diseases or chronic illnesses, must completely avoid eating raw or undercooked shellfish.
