An update by Group E15 (Heavy metals and other elements in milk and milk products) Bulletins of IDF Nos. 105/1978 and 152/1982 based on literature, the Group’s experience and the results of a Questionnaire 2386/E
The normal trace element content of milk and milk products is usually very low since the cow is known to function as a highly efficient filter. Reliable analytical measurements are essential in order to monitor influences from the environment on the levels of trace elements, to control possible secondary contamination during processing, packaging and storage of milk or milk products and to estimate the significance of trace element contents with regard to product quality or health risk.
This bulletin contains a chapter on general recommendations on sampling and analysis of trace elements in milk and milk products. Detailed information on methods for a specific element – copper, iron, lead, cadmium, mercury, tin, zinc, iodine and selenium – is found in the chapter dealing with that element.
