==Foreign Bodies==
Foreign body contamination is the main cause of customer complaints & litergation relating to food hazards in the UK & other develooped countries. The foreign bodies may be metal, stone, plastic, hair etc.... Cereals, bread & flour are most commonly affected followed by processed meats, poultry & fish. Deteection systems may be in place. They may consist of metal detectors, X-ray machines or just visual inspection (1).

Most overt food borne disease is caused by this category of hazards. Consequently this section will be dealt with in depth, see [[Foodborne Pathogenic Organisms - WikiVPH|Foodborne Pathogenic Organisms]].

Although unusual, contamination of livestock with caesium-137 occurred after the Chernobyl nuclear power plant disaster in 1986.

In this context this refers to organisms who have have had their genetic make up altered by molecular bioengineering. This can bring about transgenic organisms that carry genes taken from different species.
