Sunderland World Triathlon swimmers report illness as reduced water quality detected in Roker Beach
Swimmers who took part in the World Triathlon Championship have reported falling ill, prompting an investigation by event organisers and health bosses.
The event was held in Sunderland for the first time between 29 and 30 July with thousands turning out to watch the races.
However, athletes reported becoming sick in the days after the event.
Data published by the Environment Agency has shown reduced water quality in the Roker Beach area while an elevated level of E.coli was also reported in the area.
British Triathlon said the water analysed was outside of the swim area for the event but are working alongside Sunderland City Council and UK Health Security Agency North East (UKHSA North East) to gather more information.
Participants who have become unwell after the event are urged to report it in order to assist the investigation.
A statement on the British Triathlon website said: "British Triathlon and World Triathlon are aware of illness among some participants following AJ Bell 2023 World Triathlon Championship Series Sunderland.
"We have communicated with participants regarding the situation and we will continue to work with Sunderland City Council and the UKHSA North East in line with their routine processes to establish further information.
"We are aware there are concerns around water quality results for a test taken on 26 July by the Environment Agency as part of their regular testing in the local area.
"These tests were taken outside of the Roker Pier arms and not in the body of water used for the swim and published on Monday 31 July following the event."
British Triathlon added that they had conducted their own tests of the swimming area before and after the event and the results were deemed acceptable.
A UKHSA North East statement said: "UKHSA’s North East Health Protection team is working with British Triathlon and Sunderland City Council following reports of illness in a number of participants who took part in the UK leg of the World Triathlon Championship Series in Sunderland.
Organisers of the event have written to all participants to ensure they are aware and to advice anyone with symptoms to seek medical advice.
"The risk to the wider public is very low."
A spokesperson for Sunderland City Council said: "We are working with British Triathlon and the UK Health Security Agency North East (UKHSA North East) to better understand the circumstances after a number of participants taking part in the UK leg of the World Triathlon Championship Series in Sunderland reported feeling unwell.
"British Triathlon has written to all those who took part in the event to make them aware of the situation. We would urge anyone who took part in the event and has or had symptoms of diarrhoea and vomiting, to follow the advice contained in the email from British Triathlon.
"Water testing was carried out by British Triathlon in the build up to the event and on the Sunday of the triathlon to ensure water in the area where participants swam was safe to do so. Environment Agency data showing reduced water quality was from a different stretch of water. Detailed information on the water quality testing that took place in the swim area for the event is available in a statement on the British Triathlon website.
"We are continuing to work with British Triathlon and the UK Health Security Agency North East (UKHSA North East) to understand more about the situation."
