A study which indicates the competence of global laboratories to measure heavy metals in seafood should enhance consumer confidence but there are concerns over arsenic estimates, according to a report from the EC’s Joint Research Centre.
“The outcome of the exercise was generally positive, with 80 to 96 per cent of laboratories obtaining satisfactory scores, depending on the heavy metal considered,” reported the JRC, a Directorate-General of the European Commission.
However, the centre notes: “Participants tended to underestimate the content of total arsenic, and to a lesser extent total cadmium.”
And, it said that, contrary to a previous exercise (IMEP-107 on total and inorganic arsenic in rice), the values reported for inorganic arsenic showed a large spread.
