Not sure what you mean by your question.

In Canada, food labeling laws require that MSG be identified in the ingredients/product contents section. The big problem is that MSG also goes by other names, or is included as an unspecified ingredient in pre-packaged "mixed spices or seasonings" [e.g. Chinese five spice seasoning]. If you are sensitive to MSG, avoid processed soy sauce [it's loaded with MSG], processed/packaged meats, packaged soups, packaged meat marinades, etc. Basically, if it's a salty-tasting meat-based processed food, it's a good bet that it contains MSG and/or nitrates/nitrites [equally bad for your health].
