Available on Magic, Spire and Cefas website. Bivalve mollusc (shellfish) harvesting areas are classified according to the extent of contamination shown by monitoring of *E. coli* in shellfish flesh. Treatment processes are stipulated according to the classification status of the area. The classification categories are: **Class A** (80% of samples must be ≤ 230 *E. coli*/100g; all samples must be less than 700 E. coli/100g) - molluscs can be harvested for direct human consumption **Class B** (90% of samples must be ≤ 4600 *E. coli*/100g; all samples must be less than 46000 E. coli/100g) - molluscs can be sold for human consumption: - after purification in an approved plant, or - after re-laying in an approved Class A re-laying area, or - after an EC-approved heat treatment process. **Class C** (≤ 46000 *E. coli*/100g) - molluscs can be sold for human consumption only after re-laying for at least two months in an approved re-laying area followed, where necessary, by treatment in a purification centre, or after an EC-approved heat treatment process. In all cases, the health standards in Annex III of EC Regulations 853/2004 and the microbiological criteria adopted under EC Regulation 2073/2005 must be met. Molluscs must not be subject to production or collected in prohibited areas. There are two classification systems in England and Wales: ( 1.)the annual or "temporary" classification system ( 2.)the long-term classification (LTC) system. New areas are initially given annual/temporary classifications until they meet the criteria for an LTC. Harvesting sites that do not meet LTC criteria are automatically classified under the annual/temporary classification system. Classification: Class A=1, Class B=2, Class C=3, Prohibited=4, Long Term Class B=5, Seasonal Class B/Class C=6, Seasonal ClassA/Class B=7 Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk originator Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk custodian Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS) Cefas Lowestoft Laboratory Pakefield Road Lowestoft Suffolk NR33 0HT UK data.manager@cefas.co.uk distributor Food Standards Agency (UK) data@food.gov.uk owner quarterly Mollusc Shellfish Coastal environment GEMET, version 1.0 2008-06-01 publication Human activity SeaDataNet P03 parameter discovery vocabulary 2011-03-25 revision Species distribution GEMET - INSPIRE themes, version 1.0 2008-06-01 publication Inapplicable SeaVoX Vertical Co-ordinate Coverages 2010-05-18 revision Marine Environmental Data and Information Network MEDIN metadata record availability 2012-01-11 publication data.gov.uk MEDIN metadata record availability 2012-01-11 publication otherRestrictions noLimitations otherRestrictions Public data - no limitations to reuse 10 English biota -5.50 2.00 50.00 55.75 1990-01-01 2099-01-01 Delimited Geographic Information System Unknown https://data.cefas.co.uk/view/79 Cefas Data Portal download The Cefas Data Portal contains metadata records and data sets available to download and connect to in support of our commitment to open science.
