Additional control systems to monitor harmful algal blooms which affect shellfish, coupled with a review of existing safety protocols, have been demanded by Mr Alan Reilly, the director of operations at the Food Safety Authority of Ireland.
These include the establishment of a national standard for azaspiracid (AZP), a new bio toxin almost unique to Irish waters, which has caused the closure of up to 30 bays on the south and west coasts for the harvesting of a variety of shellfish.
Mr Reilly said the escalation of algal blooms highlighted the necessity for improved analytical methods and earlier warning system for the protection of human health - shellfish feed on these algae, which often produce a tox in which can cause illness.
At an international meeting on phycotoxins in Cork, organised by the World Health Organisation and the Intergovernmental Oceanographic Commission and attended by experts from 15 countries, he said the re-established Irish Molluscan Shellfish Safety Committee would review the adequacy of existing safety control systems.
This would cover issues such as the full traceability of shellfish products, sampling protocols, improved monitoring systems, quality control in shellfish laboratories, publication of data, procedures for the closure of toxic bays and research.
"If Ireland fails to implement a comprehensive control system, it not only puts consumers at home and abroad at risk but will also damage the sustainability of the Irish bivalve industry," he said.
