The digestion of food in humans takes place in the gastrointestinal tract â a series of hollow organs (mouth, esophagus, stomach, large and small intestines) connected to form a long tube of about 24 feet in length which extends from the mouth to the anus.
Definition: Commercially prepared food designed for ease of consumption. Products designated as convenience or ready-to-eat foods are often prepared food that can be sold as hot, ready-to-eat dishes; as room-temperature, shelf-stable products; or as refrigerated or frozen products that require minimal preparation (typically just heating).
All ready-to-eat foods are marked with preparation date and disposition date. If you prepare an item that is ready-to-eat and held for over 24 hours in your food establishment, mark the potentially hazardous food with two dates  preparation or opening date and disposition or consume-by date. You may use 7 days for 41F storage temperature and use 4 days for storage at 45F.
