contaminated water, for example, dioxins, halogenated organic compounds or heavy metals. plant diseases – mycotoxins. Examples of chemical contaminants include the following:

  • mycotoxins.
  • heavy metals – lead and mercury.
  • organic pollutants – dioxins.
  • acrylamide which may result from food being processed.

What are the 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.
