Staff in environmental health jobs had no need to shut down a single restaurant in Exeter last year.
Officials paid more than 500 visits to different food outlets around the city in 2009, taking 174 food samples along the way.
While more than 200 written warnings were handed out by environmental health officers advising businesses to improve their standards, councillor Kevin Mitchell told the Mid-Devon Star that the results were otherwise pleasing.
"Two businesses were successfully prosecuted following a history of non-compliance, but not a single business needed to be shut down," he stated.
Last month, environmental health officers in Oxford temporarily closed the Café Rouge restaurant in Little Clarendon Street, following the discovery of mice and cockroaches on the premises.
It was allowed to reopen once the owners of the restaurant successfully dealt with the infestation, reported the Oxford Mail.
