A primary school has fully re-opened today after the potentially harmful bacteria legionella was found in its water supply. 

Parents were asked to collect their children from Nightingale Primary School in Ashbourne Avenue, South Woodford, on Monday afternoon after the bacteria was discovered during a routine inspection. 

The school confirmed on Tuesday that legionella, commonly found in man-made water systems, was present in two buildings and considered it 'low risk if managed correctly.  

The airborne virus can cause Legionaires' disease or a mild flu-like illness called Pontiac fever if inhaled through water droplets. 

Other symptoms include fever, chills and a dry cough. 

The school was re-opened to Year 5 and 6 pupils yesterday with staff supervising the use of hand sanitisers to prevent any risk of exposure. 

Headteacher Caz Langbridge confirmed it has fully re-opened. 

She said: "We are very pleased to inform you that the school is open fully.

"We are looking forward to seeing all the children in the morning.

"Thank you for your understanding over the past few days."

The school insists there have not been any reported illnesses linked to the water supply but parent Saira Malik believes her children's sickness is linked. 

Her children in nursery and Year 5 have both been ill since November and said her eldest has had a "cough that will not budge". 

Mother-of-three Jennifer Campbell, who has two daughters at the primary school, praised Ms Langbridge and staff in their handling of the bacteria discovery. 

She said: "The school acted responsibly and closed the doors immediately.  

The school and Redbridge Council have been approached for a comment.
