Tests of the water at Splashes swimming pool have come back clear after dozens of people fell ill following a visit.

But Medway Council says the samples were taken last Monday morning, after routine cleaning had taken place, and the tests did not cover viruses.

About 120 children and adults were violently ill after going to the pool on Friday, October 28, with some needing hospital treatment.

This figure has been disputed by the council, who say they have received 31 complaints which amounts to about 60 individual cases.

The council has been working with Public Health England to investigate the sickness outbreak.

Environmental health officers have been visiting the homes of some of those affected to gather evidence.

The pool in Bloors Lane was shut until 4pm last Monday so the changing rooms could have a deep-clean and staff have been thoroughly cleaning the pool and increased chlorine levels in the water.

Visitors who have been back in the last week said the centre now looks “spotlessly clean”.

One customer commented online: “The staff are mortified. They are certainly 100% on cleanliness at the moment.”

A Medway Council spokesman said: “Water test results for Splashes have come back clear, which means the water is clean and free of bacterial pathogens.

"While this is good news, samples were taken on Monday morning after the water had already been treated following the party as part of routine cleaning, before complaints were received.

"We are very sorry that some customers fell ill" - Medway Council

"The water test didn’t cover viruses, but it does seem likely that a customer with the highly contagious winter vomiting bug could have attended the pool and affected a number of other swimmers who began displaying symptoms of the bug shortly after their visit.

“We are very sorry that some customers fell ill after enjoying the family pool party. We acted quickly once made aware to make sure no other customers were affected.

"The pool was closed and cleaned as a matter of urgency on Monday, and the water was monitored and tested in accordance with industry guidelines.

“We have received 31 reports of illness from those who used the pool on Friday, which we estimate equates to around 60 individual cases.

"We will continue to look into what has happened with assistance from Public Health England.

“We urge customers not to visit public pools when they are feeling unwell, especially with a vomiting bug and/or diarrhoea which can spread to others very easily.

"Those with symptoms should not return to school or work, or use public facilities until they have been symptom free for 48 hours.”
