Cefas: Shellfish Classification Zones (3rd Party Data)

This is a third party spatial dataset detailing the extent and location of Shellfish Classification Zones of England and Wales. Natural Resources Wales (NRW) has access to this data from Cefas under an Open Government Licence (OGL). NRW holds historic versions of the data as well as up to date versions of the data. For instance: - CEFAS Shellfish Classification Zones 2015 (SWF Hygine) - CEFAS Shellfish Classification Zones pre 2015 (Bivalve) - CEFAS Shellfish Classification Zones

Datganiad

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: Less than or equal to 230 E. coli/100g - molluscs can be harvested for direct human consumption Class B: 90% of samples must be less than or equal to 4600 E. coli/100g: all samples must be less than 46000 E. coli/100g. - molluscs can be sold for human consumption, after purification in approved plant, or after re-laying in an approved Class A re-laying area, or after an EX-approved heat treatment process. Class C: Less than or equal to 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. Classification: Class A=1, Class B=2, Class C=3, Prohibited=4, Long Term Class B=5, Seasonal Class B/Class C=6
