Salmonella Never Leaves!



Salmonella; a form of bacteria that we’ve all heard of. We’ve all heard how dangerous and even deadly it can be,…but is there any true way to rid ourselves of it? According to researchers from the National University of Ireland, once salmonella bacteria gets into the foods we eat, it has the chance to form a biofilm on surfaces throughout the food facilities. This biofilm is extraordinarily difficult, if not impossible to kill. Using three different forms of disinfectants, none of them were capable of killing off the bacteria after it had been allowed a short seven days to grow. Even soaking the biofilms in disinfectant for over an hour failed to kill them. Why have this study now? There was a European outbreak in which 160 people from 10 different countries became sick with gastroenteritis (vomiting and diarrhea) from a form of Salmonella. The outbreak was traced back to meat from a food facility. What sparked their interest was the fact that the Salmonella seemed to be coming from a part of the factory where the meat was no longer raw, but had already been cooked all the way through. They wanted to know what made this strand of Salmonella strong enough to make it through the high temperature environments. They found that they were able to survive through creating dense layer of biofilm on the surfaces throughout the facility.


I found this article to be interesting because there are over a million cases of Salmonella per year, with 23,000 hospitalizations and a minimum of 450 fatalities. That is a huge amount of such a tiny microbe. If researchers could find a better way of fighting such a dangerous bacteria, our food would not only be healthier, but there would be less deaths from it. I do think that the article should’ve touched a bit more on how Salmonella actually develops in a place such as a food industry. It would be beneficial to know how it actually got there in the first place. Other than that, it really makes you think about where and what you may be unknowingly eating. Yuck!
