Foodservice (US English) or catering industry (British English) defines those businesses, institutions, and companies responsible for any meal prepared outside the home. This industry includes restaurants, school and hospital cafeterias, catering operations, and many other formats.
The companies that supply or sell foodservice goods (e.g. kitchen utensils, and foods) are called foodservice distributors.
