Here in America packages (cans, boxes, packs, or wraps), are required to be stamped with a date to be Best used by. Many items I will take a few risk with, I just went through some old food items that I had on hand, (all of which are mixed items in preparations) and I trowed them away. My food items in the cabinets are now all in date. Sometimes I will buy quantity and then eat many of the items and burn out or have a change of taste. It is sad that I wasted all of the money. Some of the packages only had enough for a partial prep, so I do not regard that as a waste at this time.
Does the dates really mean anything? I had rather be safe than experimental.
