There are three different types of food contamination – chemical, physical and biological. All foods are at risk of becoming contaminated, which increases the chance of the food making someone sick. It’s important to know how food can become contaminated so that you can protect against it.

What are physical contaminants?

Physical contaminants (or ‘foreign bodies’) are objects such as hair, plant stalks or pieces of plastic/metal that can occur as contaminants in food. Sometimes the object is a natural component of the food (e.g. a fruit stalk) – but in all cases it is important to find out what it is and how and when it got there.

What are called contaminants?
