A young mother and a three-year-old girl are seriously ill in hospital after allegedly contracting E.coli from a fish and chip shop.
The Llay Fish Bar on Council Street in Llay, Wrexham, North Wales, is at the centre of the suspected E.coli outbreak.
New mum Karen Morrisroe-Clutton is being treated in Wrexham Maelor Hospital where it is understood she is on a life support machine.
The second victim, who has not been named, is being treated for renal failure at Liverpool's Alder Hey Hospital.
She is related to another person who is ill with the suspected bug, although they are not in hospital.
A fourth person has also been taken ill but is not in hospital. All four are from the Wrexham area.
A spokeswoman for Wrexham Council said they obtained a court order today to keep the Llay Fish Bar closed while further investigations are carried out.
Dr Judy Hart, consultant in communicable disease control at the National Public Health Service for Wales (NPHS), said: "The NPHS and Wrexham Council's environmental health officers are investigating four cases of E.coli O157 in three families from the Wrexham area.
"Two people have been hospitalised. As a precautionary measure, a food premises in Llay was closed by the council on July 30 while investigations are carried out.
"E.coli O157 is a serious bacterial infection that causes abdominal pain and diarrhoea.
"The symptoms of E.coli O157 range from mild diarrhoea, stomach cramps and fever to bloody diarrhoea.
"Most people recover without complications, but the most severe cases can develop kidney failure."
Mrs Morrisroe-Clutton's husband, Paul, told the BBC that they had a takeaway last Monday and his wife fell ill the following day.
His wife gave birth to their son Oliver 11 weeks ago. Mr Clutton said: "We thought it was salmonella and Karen would take some medication and it would be fine but she just deteriorated.
"She's still very critical but the doctors, who are absolutely out of this world, they remain optimistic but at any moment it could get worse but she is still stable, her body is trying to fight this disease."
A businessman called Bekir Huyuk is understood to own the fish bar.
His brother, who declined to be named, said tonight: "No one is sure where it has come from. We don't know anything until we get the results from the investigation back.
"We were supposed to get them today but they have been delayed for some reason. My brother does not want to speak to the media."
A spokesman for the North Wales NHS Trust East tonight described Mrs Morrisroe-Clutton's condition as "seriously ill".Reuse content
