Why Is It So Difficult to Eradicate Salmonella?

- Salmonella is a bacterium that occurs mainly in the intestine and it is a serotype that causes food poisoning.

- Feed that is contaminated by salmonella bacteria is familiar to the animal feed industry all over the world.

- It seems it is impossible to eradicate salmonella because it forms biofilm that helps it to survive longer in factories than bacteria that didn’t form biofilm.

- Biofilm protects the bacteria because it is a slime, or a matrix, that the bacteria produces itself.

- If the salmonella forms a biofilm it is virtually resistant to disinfectants that are normally used to clean in factories.

Reflection:

I chose this article because I know that Salmonella is a big problem in the food industry. When food has been affected with salmonella, it always gets recalled because it is a big health risk. Also, I used to have a turtle and I remember when we bought it, the person at the pet store told us that turtles can spread salmonella very easily. I found it interesting that, even though salmonella is such a common bacteria and we are so technologically advanced, there still is not a disinfectant that can kill it. In conclusion, I found this article very interesting.
