2010 Shellfish farming: Classification of shellfish harvesting areas and designated shellfish waters around Shetland dataset https://portal.medin.org.uk/portal/start.php?tpc=010_2fc595f5aa73c3fd2d6c0c88e5e994a0 This map shows the location and classification boundaries of shellfish beds under the EU Shellfish Hygiene Directive. The Food Standards Agency (FSA) is responsible for ensuring that shellfish harvesting areas are monitored and classified according to European legislation. This includes responsibility for the designation of harvesting areas, setting standards and reporting the classification of harvesting areas according to the presence of faecal indicator organisms. The degree of shellfish contamination determines the degree of depuration (purification) required before the produce may be commercially marketed. Fishermen may only exploit on a commercial basis those shellfish from areas which have the appropriate FSAS hygiene classification. 20100223
