Why Is It So Difficult to Eradicate Salmonella?

Salmonella is one of the most common bacteria that cause serious illness all around the world each year. Salmonella is mostly live in the intestinal tracts of humans and other animals, including birds. Salmonella are usually transmitted to humans by eating foods contaminated with animal feces. Foods contaminated with Salmonella are mostly animal origin like beef, poultry, milk, or eggs and even some types of vegetables. Cooking usually kill the Salmonella, but they can also be founded on hand if you don’t wash your hand properly before cooking. Salmonella can also be founded in pet feces. There are many different kinds of Salmonella bacteria. Salmonella serotype typhimurium and Salmonella serotype enteritidis are the most common in the United States.
In this article Dr. Lene Karine provide the solution for many food industries’s major problem. There are some Salmonella that can manage to establish themselves in the food and fish factories. And it is very difficult to get rid of them. Dr. Karine have discovered that Biofilm help salmonella to survive longer in the factory. She says that in order to get rid of those Salmonella is to get rid of Biofilm. Biofilm, in Salmonella, have slime layer which help them protect and produce themselves. One company has studied the effect of nine most commonly used disinfectants on Salmonella. Only a product containing 70% ethanol was the most efficient.
There have been so many techniques developed over the years it fight Salmonella, none of them were efficient. Maybe getting rid of Biofilm would be the key to develop technique to fight Salmonella, but till then we would always have to be careful in what we eat and touch.
