Food past its expiration date can be referred to by several different synonyms, including expired food, spoiled food, or rotten food. Other terms that can be used to describe food that has passed its shelf life include outdated food, gone off food or past its use by date food. These terms all refer to food that has passed the expiration date printed on its packaging and is no longer safe or healthy to consume. It is important to properly dispose of expired food to avoid any potential health risks and ensure fresh foods are being consumed. Additionally, checking expiration dates on packaged foods before consuming them is a good habit to develop.
