Organic salmon was not source of contamination

THE letter from Dr Roderick O’Sullivan (‘Is farmed salmon a flying pig,’ Irish Examiner, July 1) is unfortunately inaccurate and tantamount to scaremongering.

Yes, traces of malachite green were found in a sample of Irish organic salmon taken from a British supermarket. However, the explanation discovered by the Veterinary Medical Directorate (a branch of the British Departmetn for the Environment, Food and Rural Affairs), and made public in an article in the Sunday Times on June 5, identified clearly that the source of contamination was not associated with the salmon at all.

The malachite green came from paper towels containing the carcinogen that were used by workers repackaging the fish for sale in the British supermarket. in Morrisons Newcastle.
