What is Bacterial Contamination? Bacterial contamination is a situation which occurs when bacteria end up in a location where they are not supposed to be. It is often used to refer to contamination of food by bacteria which can cause disease, but can also occur in other settings. This situation is not desirable, because it can pose a health threat and cause other problems. As a result, steps are taken to avoid contamination in settings where it can become an issue.
