Two-year-old twins Aaron and Todd Furnell went to visit the farm and in this picture, from the Mirror, lie motionless on their stomachs in adjacent hospital cots.
Todd underwent a second blood transfusion yesterday – the day a 13th child was hospitalised – after the brothers had suffered acute kidney failure.
Ms Mock said: "They’re much the same, but now they are eating a little bit, rather than having it done for them through a feeding tube. When Aaron isn’t asleep, he seems a bit more alert, but Todd is struggling a little."
Tracy Mock is among a group of parents calling on health officials to explain why they were able to visit Godstone Farm, Godstone, near Redhill, Surrey, after the first case of E.coli was brought to manager’s attention there on August 27.
Ms Mock, from Kent, and her sons visited the farm four days later.
Four young children remained seriously ill in hospital last night following the outbreak on the popular petting farm.
Twenty four adults fell ill after visiting. Yesterday the Health Protection Agency (HPA), which faced calls for a public inquiry into its handling of the outbreak, confirmed there were a total of 37 cases of E.coli infection linked to the farm, including another child who had been recently diagnosed.
Another toddler, Alfie Weaver, was being monitored by doctors at East Surrey Hospital in Redhill, where he also had blood transfusions.
The little boy was left screaming in agony when his kidneys shut down following the outbreak. He was cared for in an isolation ward but is now understood to have begun talking.
His grandfather, from Redhill, who did not want to be named, said the three-year-old has since shown signs of improvement.
"It was like a dream come true, he has been in agony for nine days," he said.
The child and his six-year-old sister were taken to Godstone Farm on the August bank holiday – several days after the first case of E.coli was reported.
His mother, Gemma Weaver, said: "We deserve answers from the farm and the Health Protection Agency about this horrific bug. This farm should have been shut down earlier in August if kids tested positive for the bug then."
In Vancouver, where another dozen kids got sick from the petting zoo, the local paper can’t decide whether it was the food or the petting zoo.
Mark Neale writes in the Belfast Telegraph this morning that those who have investigated E. coli O157 "know the risk it poses on open or petting farms. A quick scan of the literature suggests one outbreak a year can be associated with open or petting farms. E.coli, particularly the virulent 0157 variant, has always been associated with farms and farm animals. Hand-washing, alcohol gels and all manners of materials used to remove the bacteria ultimately will prove useless."
