About 2,000 people participated in the events last weekend, which included a swim off Sunderland’s blue flag Roker beach. The UK Health Security Agency (UKHSA) said it would be testing samples from those who were ill to establish the cause of the illness and any common pathogens.
An Environment Agency sampling at Roker beach on Wednesday 26 July, three days before the event, showed 3,900 E Coli colonies per 100ml, more than 39 times higher than typical readings the previous month. E coli is a bacterial infection that can cause stomach pain and bloody diarrhoea.
But British Triathlon, the governing body for triathlons in Great Britain, said the agency’s sampling results were not published until after the weekend’s events and were outside the body of the water where its competitions took place. It said its own testing results passed the required standards for the event.
The event was on a stretch of coastline that has been at the centre of a long-running battle over sewage discharges between campaigners and the government concerning regulatory failures.
This is the best summary I could come up with:
At least 57 people fell ill with sickness and diarrhoea after competing in sea swimming events at the World Triathlon Championship Series in Sunderland, health officials confirmed this weekend.
An Environment Agency sampling at Roker beach on Wednesday 26 July, three days before the event, showed 3,900 E Coli colonies per 100ml, more than 39 times higher than typical readings the previous month.
Ailith Eve Harley-Roberts, 51, from Leeds, who competed in the standard category with a 1,500-metre sea swim, said she had not fallen ill but fellow competitors suffered stomach upsets.
Eva Perrin, science and research officer at campaign group Surfers Against Sewage, said: “The sample taken on 26 July showed unprecedented levels of E coli well over what is natural for this water body or safe for human recreational use, and urgently needs to be investigated.”
A pre-action letter was sent on his behalf by the Environmental Law Foundation to the Department for Environment, Food and Rural Affairs (Defra) and the regulator Ofwat in June for a proposed judicial review, alleging there were 122 discharges in 2021 alone from the Whitburn sea outfall, totalling 821,088 tonnes of sewage and storm water.
Data published by the charity the Rivers Trust based on returns from water firms shows a sewer storm overflow discharged into the Wear Estuary, near the triathlon event, 28 times in 2022 for a total of 370 hours.
