Food to keep on hand could easily include even peanut butter and honey, as these are normally readily available and have a long shelf life (as does Spam). Most canned food will store safely for 2 years, except high acidic varieties such as tomatoes (and foods containing vinegar) and these should be used within 1 year. Most dates on canned goods indicate when it was manufactured. But, by all means please acquire some emergency type long life foods for numerous reasons. Most offer long life spans, are quick and easy to prepare, offer compact storage ability and offer quick grab and go portability.
