The Icelandic Food and Veterinary Authority (MAST) consists of a head office, an office for import and export control, and regional offices. MAST supervises the food control activities of the municipalities. MAST is subordinate to ANR and is the central authority in the field of food safety, animal health and animal welfare. MAST is involved in risk communication as well as preparatory work for legislation (in support of ANR activities).

MAST is responsible for inspections and controls during the import and export of food, feed, plants and live animals. In the area of food of animal origin, MAST carries out controls and inspections during primary production, in slaughterhouses, during the processing of meat and fish, and in dairies and during egg production.

MAST cooperates with Matís Ltd. with regard to risk assessment in the area of food safety and human exposure to contaminants. Matís Ltd. provides scientific advice and support in the area of chemical and microbiological food safety, monitoring of food safety risks as well as laboratory diagnostic services in the field of chemical and microbiological risks.

MAST cooperates with the Institute for Experimental Pathology at Keldur, University of Iceland, with regard to risk assessment in the area of animal disease. The Institute for Experimental Pathology at Keldur also provides scientific advice and support in the areas of animal and human disease, monitoring human health, as well as laboratory diagnostic services in the field of animal disease.
