What’s a physical contaminant of food?

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.
