Does every consumable item need an expiration date?

Not every consumable item requires an expiration date, but many do for safety and quality reasons. Perishable items, like dairy and meat, need clear dates to prevent foodborne illnesses, while non-perishable items might indicate a "best by" date for optimal flavor and freshness. However, some products, like certain canned goods or dry grains, can remain safe for consumption well past a date if stored properly. Ultimately, regulations and industry standards often dictate which items require labeling.
