New research on potentially harmful bacteria in Ireland’s seas, lakes and rivers highlights the need to revise current EU bathing water quality monitoring criteria, NUI Galway (NUIG) researchers have said.

Analyses of 111 samples taken from 50 locations in Galway city and county, Cork city and county and Fingal, Dublin, between 2016 and 2019 detected a pathogenic form of E. coli .

This form of E. coli called Shiga-toxigenic E.coli (STEC) can lead to potentially life-threatening infection in about 10% of cases, the researchers state.

As Afloat reported earlier, the bacteria was detected in 57% of 84 sea waters where samples were collected – all of which are deemed of “good” or “excellent” quality, based on current EU bathing water monitoring criteria.

STEC was also detected in 78% of the 27 lake and river samples tested.

Shiga-toxigenic E.coli (STEC) is carried naturally by cattle and sheep.

The NUIG Antimicrobial Resistance and Microbial Ecology (ARME) research team says that a microscopic quantity has the potential to do serious harm to humans.

It warns that ingestion could cause serious illness including bloody diarrhoea while about 30% of STEC cases require hospitalisation and about 10% develop haemolytic uremic syndrome, a potentially fatal complication that causes renal failure.

Ireland has the highest rate in Europe, the team states. Figures from the Health Protection Surveillance Centre record that in 2016 Ireland reported 16.6 cases of STEC per 100,000.

This is higher than the next worst offenders - Switzerland (8.2/100,000 population) and Norway (7.3/100,000 population) respectively- they point out.

“These findings highlight the need to consider revision of current EU bathing water quality monitoring criteria to consider characteristics of the organisms present,”Prof Dearbháile Morris of ARME says.

Her team is asking people to take the www.nuigalway.ie/bluespaces survey. It aims to “build a picture of what is stopping people from fully utilising our seas, lakes and rivers, and to help identify problem areas”.

The survey is part of the four year PIER project (Public Health Impact of Exposure to antibiotic Resistance in recreational waters), funded by the Environmental Protection Agency (EPA).

The researchers are asking the public to take the survey to help identify the barriers and enablers for people’s interaction with blue spaces - our beaches, seas, lakes and rivers.

“The most recent bathing water quality data reports that 96% of our identified natural bathing waters meets the minimum required standard,” Prof Morris, who is principal investigator on the PIER project,says.

“However, our research has revealed the presence of organisms of public health concern in waters designated as of excellent quality in some cases,” she points out.

NUI Galway researchers will use the findings from the PIER project to create a systems map to identify problem areas, identify and prioritise collaborative change strategies and explore stakeholder engagement opportunities.

“No matter how much or little you engage with our waters, your contribution will help co-design strategies to maintain and protect our waters for future generations,” Dr Sinead Duane, postdoctoral researcher with the project, says.

#beach – Clare County Council, on the advice of the Health Service Executive (HSE), has today (Saturday, 21 July 2012) lifted restrictions relating to public bathing at Lahinch, Kilkee and Spanish Point beaches.

The Council confirmed that the preliminary results of water samples taken from the three bathing areas yesterday (Friday) have shown a dramatic reduction of levels of bacteria in the water. The Council and HSE said an improvement in weather conditions in recent days has been the main contributory factor to the positive results.

As previously reported on Afloat.ie the prohibition on bathing at the three locations was put in place on Friday after the results of routine tests on water samples at the three beaches showed up elevated levels of bacteria.

According to Anne Haugh, Director of Services, Clare County Council: "On the advice of the HSE and following analysis of water samples, the Council is delighted to be able to announce the lifting of all restrictions relating to bathing at Lahinch, Kilkee and Spanish Point. Public notices indicating that swimming and surfing at the three locations are no longer prohibited are being erected this afternoon, while the Blue Flag at Lahinch and Kilkee beaches have been restored having been temporarily withdrawn on Friday. Lifeguards at each of the three bathing areas also have been instructed to remove all red flags which had indicated that bathing was prohibited."

Liam Griffin, Water Safety Officer, Clare County Council added: "Clare County Council would like to thank the public for their understanding and cooperation over the past 24 hours. The local authority also acknowledges the valuable role played by the media in promoting the public health notices."

Marine Protected Areas (MPAs) - FAQS

Marine protected areas (MPAs) are geographically defined maritime areas where human activities are managed to protect important natural or cultural resources. In addition to conserving marine species and habitats, MPAs can support maritime economic activity and reduce the effects of climate change and ocean acidification.

MPAs can be found across a range of marine habitats, from the open ocean to coastal areas, intertidal zones, bays and estuaries. Marine protected areas are defined areas where human activities are managed to protect important natural or cultural resources.

The world's first MPA is said to have been the Fort Jefferson National Monument in Florida, North America, which covered 18,850 hectares of sea and 35 hectares of coastal land. This location was designated in 1935, but the main drive for MPAs came much later. The current global movement can be traced to the first World Congress on National Parks in 1962, and initiation in 1976 of a process to deliver exclusive rights to sovereign states over waters up to 200 nautical miles out then began to provide new focus

The Rio ‘Earth Summit’ on climate change in 1992 saw a global MPA area target of 10% by the 2010 deadline. When this was not met, an “Aichi target 11” was set requiring 10% coverage by 2020. There has been repeated efforts since then to tighten up MPA requirements.

Marae Moana is a multiple-use marine protected area created on July 13th 2017 by the government of the Cook islands in the south Pacific, north- east of New Zealand. The area extends across over 1.9 million square kilometres. However, In September 2019, Jacqueline Evans, a prominent marine biologist and Goldman environmental award winner who was openly critical of the government's plans for seabed mining, was replaced as director of the park by the Cook Islands prime minister’s office. The move attracted local media criticism, as Evans was responsible for developing the Marae Moana policy and the Marae Moana Act, She had worked on raising funding for the park, expanding policy and regulations and developing a plan that designates permitted areas for industrial activities.

Criteria for identifying and selecting MPAs depends on the overall objective or direction of the programme identified by the coastal state. For example, if the objective is to safeguard ecological habitats, the criteria will emphasise habitat diversity and the unique nature of the particular area.

Permanence of MPAs can vary internationally. Some are established under legislative action or under a different regulatory mechanism to exist permanently into the future. Others are intended to last only a few months or years.

Yes, Ireland has MPA cover in about 2.13 per cent of our waters. Although much of Ireland’s marine environment is regarded as in “generally good condition”, according to an expert group report for Government published in January 2021, it says that biodiversity loss and ecosystem degradation are of “wide concern due to increasing pressures such as overexploitation, habitat loss, pollution, and climate change”.

The Government has set a target of 30 per cent MPA coverage by 2030, and moves are already being made in that direction. However, environmentalists are dubious, pointing out that a previous target of ten per cent by 2020 was not met.

Conservation and sustainable management of the marine environment has been mandated by a number of international agreements and legal obligations, as an expert group report to government has pointed out. There are specific requirements for area-based protection in the EU Marine Strategy Framework Directive (MSFD), the OSPAR Convention, the UN Convention on Biological Diversity and the UN Sustainable Development Goals. 

Yes, the Marine Strategy Framework directive (2008/56/EC) required member states to put measures in place to achieve or maintain good environmental status in their waters by 2020. Under the directive a coherent and representative network of MPAs had to be created by 2016.

Ireland was about halfway up the EU table in designating protected areas under existing habitats and bird directives in a comparison published by the European Commission in 2009. However, the Fair Seas campaign, an environmental coalition formed in 2022, points out that Ireland is “lagging behind “ even our closest neighbours, such as Scotland which has 37 per cent. The Fair Seas campaign wants at least 10 per cent of Irish waters to be designated as “fully protected” by 2025, and “at least” 30 per cent by 2030.

Nearly a quarter of Britain’s territorial waters are covered by MPAs, set up to protect vital ecosystems and species. However, a conservation NGO, Oceana, said that analysis of fishing vessel tracking data published in The Guardian in October 2020 found that more than 97% of British MPAs created to safeguard ocean habitats, are being dredged and bottom trawled. 

There’s the rub. Currently, there is no definition of an MPA in Irish law, and environment protections under the Wildlife Acts only apply to the foreshore.

Current protection in marine areas beyond 12 nautical miles is limited to measures taken under the EU Birds and Habitats Directives or the OSPAR Convention. This means that habitats and species that are not listed in the EU Directives, but which may be locally, nationally or internationally important, cannot currently be afforded the necessary protection

Yes. In late March 2022, Minister for Housing Darragh O’Brien said that the Government had begun developing “stand-alone legislation” to enable identification, designation and management of MPAs to meet Ireland’s national and international commitments.

Yes. Environmental groups are not happy, as they have pointed out that legislation on marine planning took precedence over legislation on MPAs, due to the push to develop offshore renewable energy.

No, but some activities may be banned or restricted. Extraction is the main activity affected as in oil and gas activities; mining; dumping; and bottom trawling

The Government’s expert group report noted that MPA designations are likely to have the greatest influence on the “capture fisheries, marine tourism and aquaculture sectors”. It said research suggests that the net impacts on fisheries could ultimately be either positive or negative and will depend on the type of fishery involved and a wide array of other factors.

The same report noted that marine tourism and recreation sector can substantially benefit from MPA designation. However, it said that the “magnitude of the benefits” will depend to a large extent on the location of the MPA sites within the network and the management measures put in place.
