Indirect cross-contamination – where something helps the organisms move from one place to another. We call these ‘vehicles’ of contamination. Just as you would get in your car or on a bus to travel from one place to another, micro-organisms will hop on to something to travel from raw to cooked food..

What is not a type of hazard to food?
Fungi such as yeasts and moulds are microorganisms, but they are not classed as a biological hazard in food. They are responsible for food spoilage, but generally do not make food unsafe to eat. However, some types of fungi do produce hazardous toxins, which is dangerous as it can result in intoxication.
