Question: how long can you keep expired soup?
Answer: As a general rule of thumb, most canned foods (for example, canned tuna, soups, and vegetables) can be stored for two to five years, and high-acid foods (canned juices, tomatoes, pickles) can be stored for a year up to 18 months, according to the USDA. Watch out for dents and bulges in cans, though.
