Physical dangers in food are things we can see, such as dust, dirt, glass, hair, and such articles. We can break these physical hazards into two categories:

1. Physical dangers that come from the food itself. (Fish bones, bones in meat, fruit seeds etc.)

2. Foreign objects that end up in the food because they could not be avoided during planting, harvesting, transporting, and producing, or technical errors. (Metal, glass, bolts and nuts, stones etc.)
