Food safety is a major public health concern worldwide and
food consumption has been identified as the major pathway for
human exposure to certain environmental contaminants; accounting for over 90% of intake compared to inhalation or dermal routes
of exposure (Fries, 1995). About 30% of human cancers are caused
by low exposure to initiating carcinogenic contaminants in the diet
(Tricker & Preussmann, 1990).
