Levels of mercury in fish landed in Ireland are very low and fish is safe for consumption by the general population, latest available data finds.

This will be “comforting for the Irish seafood industry and consumers alike”, Prof Ronan Gormley of University College Dublin’s (UCD) school of agriculture and food science says.

Writing in UCD’s SeaHealth e-bulletin, Prof Gormley explains that a monitoring programme was put in place for fish landed at major Irish fishing ports in response to the introduction of maximum limits for mercury in fishery products in 1993.

The monitoring by Ireland’s Marine Institute has found that mercury levels of fish and shellfish landed at Irish ports are low and “well within the EU human-consumption tolerance level”.

“However, these catches do not include deepwater species such as shark, swordfish, marlin and tuna,” Prof Gormley notes.

Mercury is a naturally occurring heavy metal found in air, water and soil, but mercury from industrial centres can travel miles before “raining into the ocean in organic form as methyl mercury”, he explains.

“Fish become contaminated, leading to public health concerns about different species and their mercury levels,” he notes.

In 2004 the EU Commission asked the European Food Safety Authority to consider data collected by member states.

It published its opinion, with emphasis on mercury intake from fish by vulnerable groups such as women of childbearing age, breastfeeding women and young children to raise awareness in all national authorities with responsibility for public health.

Prof Gormley notes that large, predatory fish such as shark, tarpon, swordfish and tuna accumulate higher levels of mercury over a long lifetime.

“These species are often migratory, and it is not possible to exclude fish from particular waters where background levels of mercury contamination might be high,” he says.

However, data shows that EU consumers who eat average amounts (300-350g a week) of fishery products are not likely to be exposed to unsafe levels of methylmercury.

Consumers who eat a lot of fish may be at higher risk, but at time of issue of the EC note (2004) there was insufficient data to specify the situation in all member states.

Maximum levels of mercury in fish were amended in 2022, he notes.

Levels were lowered for cephalopods (eg, squid, octopus, cuttlefish, nautilus) and marine gastropods (eg, abalone, conches, periwinkles and whelks) to 0.5 or 0.3mg/kg. Levels in shark, swordfish, pike and tuna were maintained at 1mg/kg.

Consumption of shark, swordfish, marlin and fresh tuna in Ireland is relatively low, apart from canned tuna which is increasing in popularity.

Latest advice is that pregnant or breastfeeding women and young children should not exceed two 226g cans a week.

Other adults and young people should continue to eat tuna and fish products as components of a healthy diet, Prof Gormley says.

Mercury levels of fish and shellfish landed by fishing boats at Irish ports are low and well within EU guidelines for human consumption, as underscored by a recent briefing from UCD’s Institute of Food and Health.

However, as Derek Evans says in his Angling Notes for The Irish Times this week, these catches do not include deep-water, often migratory species such as shark, swordfish and tuna — the latter of which is being consumed in Ireland increasing quantities in its canned variety.

It’s advised that young children as well as pregnant or breastfeeding people limit their intake to two 226g cans of tuna a week as a precaution.

But the science experts adds that the general population need not fear any fish products as part of a healthy balanced diet.

How to sail, sailing clubs and sailing boats plus news on the wide range of sailing events on Irish waters forms the backbone of Afloat's sailing coverage.

We aim to encompass the widest range of activities undertaken on Irish lakes, rivers and coastal waters. This page describes those sailing activites in more detail and provides links and breakdowns of what you can expect from our sailing pages. We aim to bring jargon free reports separated in to popular categories to promote the sport of sailing in Ireland.

The packed 2013 sailing season sees the usual regular summer leagues and there are regular weekly race reports from Dublin Bay Sailing Club, Howth and Cork Harbour on Afloat.ie. This season and last also featured an array of top class events coming to these shores. Each year there is ICRA's Cruiser Nationals starts and every other year the Round Ireland Yacht Race starts and ends in Wicklow and all this action before July. Crosshaven's Cork Week kicks off on in early July every other year. in 2012 Ireland hosted some big international events too,  the ISAF Youth Worlds in Dun Laoghaire and in August the Tall Ships Race sailed into Dublin on its final leg. In that year the Dragon Gold Cup set sail in Kinsale in too.

2013 is also packed with Kinsale hosting the IFDS diabled world sailing championships in Kinsale and the same port is also hosting the Sovereign's Cup. The action moves to the east coast in July with the staging of the country's biggest regatta, the Volvo Dun Laoghaire regatta from July 11.

Our coverage though is not restricted to the Republic of Ireland but encompasses Northern Ireland, Scotland, Wales and the Irish Sea area too. In this section you'll find information on the Irish Sailing Association and Irish sailors. There's sailing reports on regattas, racing, training, cruising, dinghies and keelboat classes, windsurfers, disabled sailing, sailing cruisers, Olympic sailing and Tall Ships sections plus youth sailing, match racing and team racing coverage too.

Sailing Club News

There is a network of over 70 sailing clubs in Ireland and we invite all clubs to submit details of their activities for inclusion in our daily website updates. There are dedicated sections given over to the big Irish clubs such as  the waterfront clubs in Dun Laoghaire; Dublin Bay Sailing Club, the Royal Saint George Yacht Club,  the Royal Irish Yacht Club and the National Yacht Club. In Munster we regularly feature the work of Kinsale Yacht Club and Royal Cork Yacht Club in Crosshaven.  Abroad Irish sailors compete in Royal Ocean Racing Club (RORC) racing in the UK and this club is covered too. Click here for Afloat's full list of sailing club information. We are keen to increase our coverage on the network of clubs from around the coast so if you would like to send us news and views of a local interest please let us have it by sending an email to [email protected]

Sailing Boats and Classes

Over 20 active dinghy and one design classes race in Irish waters and fleet sizes range from just a dozen or so right up to over 100 boats in the case of some of the biggest classes such as the Laser or Optimist dinghies for national and regional championships. Afloat has dedicated pages for each class: Dragons, Etchells, Fireball, Flying Fifteen, GP14, J24's, J80's, Laser, Sigma 33, RS Sailing, Star, Squibs, TopperMirror, Mermaids, National 18, Optimist, Puppeteers, SB3's, and Wayfarers. For more resources on Irish classes go to our dedicated sailing classes page.

The big boat scene represents up to 60% of the sail boat racing in these waters and Afloat carries updates from the Irish Cruiser Racer Association (ICRA), the body responsible for administering cruiser racing in Ireland and the popular annual ICRA National Championships. In 2010 an Irish team won the RORC Commodore's Cup putting Irish cruiser racing at an all time high. Popular cruiser fleets in Ireland are raced right around the coast but naturally the biggest fleets are in the biggest sailing centres in Cork Harbour and Dublin Bay. Cruisers race from a modest 20 feet or so right up to 50'. Racing is typically divided in to Cruisers Zero, Cruisers One, Cruisers Two, Cruisers Three and Cruisers Four. A current trend over the past few seasons has been the introduction of a White Sail division that is attracting big fleets.

Traditionally sailing in northern Europe and Ireland used to occur only in some months but now thanks to the advent of a network of marinas around the coast (and some would say milder winters) there are a number of popular winter leagues running right over the Christmas and winter periods.

Sailing Events

Punching well above its weight Irish sailing has staged some of the world's top events including the Volvo Ocean Race Galway Stopover, Tall Ships visits as well as dozens of class world and European Championships including the Laser Worlds, the Fireball Worlds in both Dun Laoghaire and Sligo.

Some of these events are no longer pure sailing regattas and have become major public maritime festivals some are the biggest of all public staged events. In the past few seasons Ireland has hosted events such as La Solitaire du Figaro and the ISAF Dublin Bay 2012 Youth Worlds.

There is a lively domestic racing scene for both inshore and offshore sailing. A national sailing calendar of summer fixtures is published annually and it includes old favorites such as Sovereign's Cup, Calves Week, Dun Laoghaire to Dingle, All Ireland Sailing Championships as well as new events with international appeal such as the Round Britain and Ireland Race and the Clipper Round the World Race, both of which have visited Ireland.

The bulk of the work on running events though is carried out by the network of sailing clubs around the coast and this is mostly a voluntary effort by people committed to the sport of sailing. For example Wicklow Sailing Club's Round Ireland yacht race run in association with the Royal Ocean Racing Club has been operating for over 30 years. Similarly the international Cork Week regatta has attracted over 500 boats in past editions and has also been running for over 30 years.  In recent years Dublin Bay has revived its own regatta called Volvo Dun Laoghaire Regatta and can claim to be the country's biggest event with over 550 boats entered in 2009.

On the international stage Afloat carries news of Irish and UK interest on Olympics 2012, Sydney to Hobart, Volvo Ocean Race, Cowes Week and the Fastnet Race.

We're always aiming to build on our sailing content. We're keen to build on areas such as online guides on learning to sail in Irish sailing schools, navigation and sailing holidays. If you have ideas for our pages we'd love to hear from you. Please email us at [email protected]
