Answer to Question #90065 in Microbiology for kim

Question

how do u prevent food spoilage from listeria and how/why it works/?

Answer 1

As listeria is resistant to low temperatures, the refrigerators are not efficient for the prevention of food spoilage from listeria. However, high temperatures lead to the destruction of the bacteria cells. As a result, cooking associated with thermal treatment (i.e., boiling) is enough to kill listeria in food from animal sources. Fresh vegetables and fruits must be washed thoroughly before eating. Keeping of uncooked meats separate from vegetables and cooked meals will help to avoid the distribution of the bacteria to the products that will not be cooked. At last, hands, knives, and cutting boards must be thoroughly washed after handling raw food. The procedures will help to avoid contamination of other products.
