The children attended the Dreams Daycare Nursery
An Aberdeenshire nursery closed since two children were struck down with E.coli O157 has reopened.
Food, water and environmental samples tested negative after children from Dreams Daycare Nursery in Insch were infected.
The nursery reopened on Tuesday to staff and children who have had two negative test results.
The building has had a precautionary clean. The source of the infection remains unknown.
Sally Jaffray, co-owner of the Dreams Daycare Nursery, said: "The nursery was inspected by a representative from environmental health.
"No indication of the E.coli O157 strain has been found at the nursery.
"We have worked closely with the healthcare professionals and are now delighted to be reopening the nursery to staff and children who have had two negative test results.
"We have received a tremendous amount of support from the local community and we look forward to welcoming the children back to the nursery."
Staff have voluntarily been put forward for hygiene and infection refresher courses.
The children, who have been released from hospital, tested positive for the O157 strain.
The NHS Grampian outbreak control team said on Monday that no further cases of E.coli O157 had been identified.
