The statement commonly viewed below ingredient lists, "may contain traces of..." means that the equipment and facilities used in manufacturing a particular product are also used to manufacture other products containing milk, nuts, etc. Despite thorough and complex cleaning, tiny traces of previous products cannot be completely excluded and the remainder may cause an allergic reaction by very sensitive allergy sufferers. This statement is purely a precaution and only relevant for those who react to trace amounts of the indicated substances. This does not mean that the named substances are added to the product as an ingredient. For people with an intolerance that is the result of malabsorption, such as lactose-malabsorption, these statements are irrelevant. If you have concerns about your allergy or intolerance levels, always contact your doctor and/or nutritionist.
