A Subway restaurant in the city centre was given a zero star food hygiene rating.
The branch in Exchange Street East, which is run under a franchise, was inspected by Liverpool City Council on July 27. It was awarded a zero-star food hygiene rating.
The assessment found "urgent improvement necessary" in hygienic food handling, cleanliness and condition of the facilities and building and management of food safety. Following the inspection, the Exchange Street East branch temporarily closed, but has since fully re-opened.
