In order to sell a food product within the United States or Canada, the equipment used to manufacture said product must past a sanitation test to guarantee a minimum level of cleanliness. These guidelines ensure that no food or beverages transmit harmful bacteria or diseases and are safe for consumption.
The NSF/ANSI Standards are an official set of regulatory guidelines for monitoring and evaluating food production devices and facilities within the United States. There are several public and private enterprises that offer inspection services and are capable of issuing accreditation approval. For example, the Intertek corporation is officially NSF/ANSI certified, which means it is sanctioned by the government to judge sanitation standards in food and beverage products. It also issues a certificate of approval upon a successful inspection.
Sanitation regulation has been a long-running issue within the United States, dating back to the early days of the Industrial Revolution. At the time, new technology was introduced to improve the speed and capacity of food production, yet government oversight was slow to keep pace with the changing landscape. As a result, large amounts of food were produced in unsanitary environments. Upton Sinclair's "The Jungle" and other books and pieces of journalism highlighted the ways both workers and food preparation equipment were being abused and the related health concerns that arose.
