Physical hazards can contaminate food mechanically. Physical hazards may include foreign bodies in the food, visible to the eye, such as
- dust, dirt, soil
- stones, buttons, nails, fragments of wood and metal, etc.
- hair, sticking plaster, cigarette butts, etc.
- dead insects and other pests, and their droppings, etc.
- parts that have come off equipment used to manufacture food, fragments of packaging material, etc.
- other bodies not intended to be contained in the food.
Foreign bodies can be prevented from gaining access into foods by looking after the cleanness of the work environment and maintenance of equipment, following neat work practices, and preventing the entry of pests into the food establishment.
