On the market, tuna fish can mostly be found as canned food (tuna in oil, spiced tuna, tuna in its own juice). The fresh fish is commercialized in parts (steak, fillet).
Food containing tuna is correspondingly labelled. There are some exceptions such as: fish pie, terrine of fish or instant fish meals. In such products, the list of ingredients should be carefully read.
You can find alternatives to tuna as well as other kinds of fish when extending ImuPro Basic to ImuPro Complete.
