• Monitoring results for trace metals and organohalogens in shellfish (2015) and physicochemical parameters and trace metals in seawater (2016) in accordance with Shellfish Waters Directive. CHEMREP 2018-003

      Marine Institute (Marine Institute, 2018)
      Directive 2006/113/EC on the Quality Required of Shellfish Waters, also referred to as the Shellfish Waters Directive (SWD) requires the monitoring of, inter alia, certain physicochemical parameters including trace metal contaminants in order to assess and protect the quality of shellfish growing waters and the shellfish harvested from them. The SWD is concerned with the quality of shellfish waters and applied waters designated by the Member States as needing protection or improvement in order to support shellfish (bivalve and gastropod molluscs) life and growth and thus to contribute to the high quality of shellfish products directly edible by man. This report details the Marine Institute’s (MI) monitoring results for physicochemical parameters sampled in seawater and shellfish tissue from designated Shellfish Waters and specifically: Dissolved trace metal concentrations and other physiochemical parameters in seawater sampled from Irish Shellfish Waters in 2016 and trace metal and organohalogen concentrations in shellfish sampled in 2015.
    • Report on analysis of shellfish samples for the presence of Yessotoxins (YTX)

      Marine Institute (Marine Institute, 2001)
      In order to determine the cause of the positive mouse bioassay results obtained in mussel samples from several shellfish production areas (including Bantry Bay, Kenmare Bay, Cromane and Lough Foyle), samples were sent in December 2000 and January 2001 for analysis. Positive mouse bioassay results were obtained, using the Yasumoto (1978) assay, in the EU Reference Laboratory and using the Yasumoto (l 984) assay in the Italian Reference Laboratory. ASP toxins, Azaspiracid, Okadaic acid and DTXs were not detected. Yessotoxin, homoYessotoxins and analogues of Yessotoxins were not detected in the samples sent to the EU Reference Laboratory or the Italian Reference Laboratory. Prof. Yasumoto detected the presence of Yessotoxin and 45-hydroxyYessotoxin at the Japan Food Research Laboratory. 45-hydroxyYessotoxin is a shellfish metabolite of Yessotoxin, which occurs with time as the YTX is oxidised by the shellfish. The shellfish samples in which Yessotoxin and 45-hydroxy Yessotoxin were detected were taken from Bantry Bay, Roaring Water Bay (Summer 2000) and Mulroy Bay. If the initial detection of Yessotoxin and 45-hydroxyYessotoxin is confirmed in other samples, the Irish biotoxin management regime and the production cycles for shellfish (in particular mussels) will have to be adapted to encompass YTX.
    • Summary Report on 2016 Residue Monitoring of Irish Farmed Finfish and 2016 Border Inspection Post Fishery Product Testing undertaken at the Marine Institute

      Marine Institute (Marine Institute, 2018)
      On behalf of the Department of Agriculture, Food and Marine (DAFM), the Marine Institute carries out monitoring of chemical residues in finfish for aquaculture sector. This monitoring is set out in the annual National Residue Control Plan, which is approved by the European Commission, and is an important component of the DAFM food safety controls and is implemented under a service contract with the Food Safety Authority of Ireland. Since 1999, the Marine Institute has implemented the National Residues Monitoring Programme for aquaculture. This is carried out on behalf of the Sea Fisheries Protection Authority, which is the responsible organisation for residue controls on farmed finfish. The outcome for residues levels in farmed finfish during 2016 remains one of consistently low occurrence. In 2016, in excess of 691 tests and a total of 1,933 measurements were carried out on 136 samples (i.e. 126 target samples & 10 suspect samples) of farmed finfish for a range of chemical substances, including banned and unauthorised substances, various authorised veterinary treatments and environmental contaminants.
