The owners of a U.K. petting zoo accused of animal welfare offences and bad food safety have withdrawn their application for a zoo licence.

Northern Echo reports that Tweddle Children’s Animal Farm, in Blackhall Colliery, County Durham, has also removed some of its more exotic animals.

Earlier this year, the council’s environmental health officers and the Department for the Environment, Food and Rural Affairs visited the farm following an undercover investigation by the Captive Animals Protection Society. The charity said it had found traces of E coli and dead animals decomposing near a children’s play area.

It also said the bodies of dead animals, including a meerkat and tortoise, had been stored in a freezer on top of food for animals, while staff working with animals were working in the cafe wearing the same clothes.

Tweedle also did not have the required licence for a zoo.

The council said no traces of E coli were reported but head teachers who may have been planning school visits were warned about its investigation.
