The gastrointestinal-tract portion running from the stomach’s lower opening through to the cloaca or the anus. Slaughtered animals’ intestines form a substantial part of the edible offal; after thorough cleaning they can serve as casings for meat products such as sausages. Thorough cleaning and careful inspection are essential, since intestinal contents carry heavy microbial loads that must never reach the finished product. Natural casings remain highly prized for their bite and appearance, and their preparation is a skilled, hygiene-critical craft.
