Food contamination refers to the presence in food of harmful chemicals and microorganisms which can cause consumer illness.rocessing contaminants are generated during the processing of foods (e.g., heating, fermentation). They are absent in the raw materials, and are formed by chemical reactions between natural and/or added food constituents during processing.
Food processing may also be a source of cross-contamination, such as contamination of nonallergenic foods with known food allergens. Migrants from Packaging Materials. Direct contact of foods with packaging materials can result in chemical contamination caused by migration of certain substances into foods.recursors of these contaminants can occur naturally in the food matrix, such as in the case of acrylamide being formed during the Maillard reaction between the amino acid asparagine and a reducing sugar (especially in potato-and cereal-based, heat-treated products).
