In New York City, there is an extensive water supply system that supports several programs and infrastructure pertaining to the city's food supply. City officials, agencies, and organizations cooperate with rural farmers to grow food more locally, as well as protect waterways in the New York metropolitan area. The New York City Department of Education operates a school-time and summertime breakfast/lunch program. The city is also deprived of supermarkets in several neighborhoods, and the city government has addressed the problem by allowing extra street vendors to operate. To encourage food safety, the government also operates a restaurant-grading system that it introduced in 2010. The various food programs have made the city a model for food systems internationally.
