PET corners across Dorset say they’re already doing all they can to prevent infection.

A Health Protection Agency report has suggested tighter guidelines for the popular attractions, following an E.coli outbreak in Surrey which hospitalised 27 people and left some children with damaged kidneys.

Sandra Palmer-Snellin of Farmer Palmer’s, in Organford, thought the National Farm Attractions Network’s involvement had prevented a dramatic ban.

“It would be devastating for kids wanting to get out and about,” she said. “And a very serious over-reaction.

“Just think of all the farmer’s children who’ve grown up in completely un-sanitised places, and now have great immune systems.”

She says common-sense initiatives like not allowing eating where animals have free access make all the difference.

“We’ve got a great record over 11 years,” she said. “After the Surrey incident people expected something else to be done, and we put in extra supervision.

“Some places are highly professional, but others aren’t, and it’s right to bring them into line.”

Alfie O’Connell owns Putlake Adventure Farm, near Swanage, and welcomes inspections.

“That’s the way it should be,” he said.

“But providing people wash their hands continually, there’s no issue in my eyes.

“My 13 grandchildren grew up playing with animals all the time, and nothing bad ever happened.

“We have thousands of visitors every month, but after Surrey trade died a death.”

Hurn’s Adventure Wonderland has a Cuddles Corner with rabbits and guinea pigs.

Managing director Russell Lucas-Rowe said: “An awful lot of children don’t get the opportunity to interact with animals.

“We give them that chance, and they leave us much, much better informed.

“It would be sorely missed.”

All three centres have basins, antibacterial soap and information signs.
