The National Sanitation Foundation (NSF)[1] is a public health nonprofit organization[2] headquartered in Ann Arbor Charter Township, Michigan, United States.[3] It tests and certifies foods, water, and consumer products.[2] It also facilitates the development of standards for these products,[2] labeling products it has certified to meet these standards with the NSF mark.[4]
NSF is accredited by the American National Standards Institute (ANSI) and the Standards Council of Canada.[5]
History
The National Sanitation Foundation (NSF) was founded in 1944 by the University of Michigan School of Public Health, in an attempt to standardize requirements around sanitation and food safety.[2] The first standards developed by the NSF set sanitation requirements on soda fountain and luncheonette equipment.[2][clarification needed]
Acquisitions
In October 2002, NSF acquired FreshCheck, a food microbiological and sanitation audit company.[6]
In March 2004, NSF acquired Quality Assurance International.[7]
In January 2013, NSF acquired INASSA Group, a Lima, Peru-based company in the industry of quality control, analytical testing, and inspection for seafood.[8]
In October 2025, NSF acquired Cambium Analytica, an analytical testing and development company in the food, beverage, and diet supplement industries.[9][10]
Certification

The NSF certifies food equipment, including food preparation and dispensing equipment, ice makers, refrigerators and freezers, dishwashing sinks, vending machines, mobile food carts, and service counters.[11] These certifications are widely recognized internationally.[11]
NSF's Food division also certifies the gluten-freeness and other similar characteristics of products, as well as certifying bottled water and packaged ice.[12]
The NSF also certifies dietary supplements through a standard it facilitated the development of adopted by ANSI (NSF/American National Standards Institute Standard 173), testing for safe levels of contaminants and that the ingredients on supplements match their labels.[2] As of 2002[update] it competed in this with the United States Pharmacopeia certification mark.[13]
The NSF also develops standards for and certifies water quality.[14] As of 2024, the US Environmental Protection Agency (EPA) sets limits on drinking water contaminants based on standards set by the NSF.[15]
The NSF Consumer Products Division tests and certifies consumer products and appliances used in and around the home.[16][17]
Laboratories
NSF maintains laboratories in North America,[18] South America,[19] Europe[18] and China.[18] NSF's laboratories are accredited by the Occupational Safety and Health Administration.[18] NSF laboratories are ISO 17025 certified (testing and calibration).[18]
The chairman of the Board of Directors, is the retired Chief Operations Officer and Executive Vice President of the McDonald's Corporation.[20] And since March 2022, the President and chief executive officer is Pedro Sancha, formerly of Ecolab and Shell.[21]
