Data from 2014 to 2020 on microbiological contamination, metals, and marine biotoxin contaminants from the classified shellfish-producing areas of the Portuguese coast are available on IPMA—Portuguese Institute for the Sea and Atmosphere—website [31 ].
Data for the period previous to 2014 was obtained from the IPMA’s database archive. All the collected data were obtained through IPMA’s official control programme. The analysis was performed in microbiology, metals and marine biotoxins laboratories—the national official laboratories accredited according to ISO 17025 [32 ].
The data collected included the microbiological, metals and biotoxins monitoring programme results; the number of samples analysed in the different laboratories per year, independently of species; and, for each production area the number of days that contamination levels exceeded the EU regulatory safety limits, causing harvesting and marketing bans to be officially put in place. The contamination impacts were assessed analysing the mussel harvesting bans in RIAV1, RIAV2, LOB, L5, L6, and L7 production areas, and donax clam harvesting bans in L8 and L9 production areas.
