The Norwegian Food Safety Authority (NFSA) is a governmental body whose aim is to implement regulations and controls to ensure that food and drinking water are as safe and healthy as possible for consumers, and to promote plant, fish and animal health. The NFSA's regulations cover ethical animal husbandry and encourage environmentally friendly production. It also regulates and controls cosmetics and animal health personnel. The NFSA's role is to draft and provide information on legislation, perform risk-based inspections, monitor food safety as well as plant, fish and animal health, provide updates on developments within its area of responsibility, and plan for emergencies. The NFSA advises and does preparatory work for legislation under the three main food ministries: LMD, NFD and HOD.

The NFSA is the regulatory authority for pesticides, and it is responsible for residues of veterinary medicines. However, the Norwegian Medicines Agency is responsible for the approval of veterinary medicines.

The NFSA is organised into two administrative levels: the head office in Oslo and 5 regions: Northern region, Central region, Southern and Western region, Eastern region, and Greater Oslo region. The regional level includes 32 district offices.
