The BBC has analysed data from the Food Standards Agency and found that one in three of the fast food outlets trading under the names of Dixy Chicken and Chicken Cottage failed to meet satisfactory levels for food hygiene when they were last inspected.
Other brands that need to make changes include Pizza Gogo and Little Chef, where around one in five of the restaurants inspected were deemed unsatisfactory.
All the chains were given the chance to check the data, but most did not comment. However, Little Chef says that it recognises it has to make progress and the company is initiating an investment programme to drive its hygiene standards up.
An FSA spokesperson told the BBC, ‘Food safety officers from local authorities will follow up with low-rated outlets and will work with them to improve hygiene standards.’
