A child sickened by E. coli O111 after visiting the Oxford County Fair has been released from the hospital, according to a spokeswoman at Maine Medical Center.

Myles Herschaft, a 17-month-old boy from Auburn, developed a dangerous complication from the E. coli infection called hemolytic uremic syndrome. He was listed in critical condition at one point, but improved and spent his first night back at home on Wednesday, according to a Facebook post by his father, Victor Herschaft.

“He will be closely monitored by his doctors for some time but we are truly blessed to have him finally back home,” a family member wrote on a fundraising website.

Another boy, 20-month-old Colton Guay of Poland (above, right), died from the same syndrome a week after visiting the fair, his father said in a Facebook post.

Maine health officials confirmed a week ago that both boys were infected by the same strain of E. coli, “making it highly likely that the cases acquired the illness from the same source.”

But Maine State Epidemiologist Siiri Bennett stopped short of linking the cases to a petting zoo at the Oxford County Fair, which ran through Sept. 19 in the town of Oxford, saying the state took samples from a barn, pens and a livestock area on the fairgrounds.

That petting zoo, which the boys visited separately, has been the only reported link between the cases.
