The low food hygiene rating given to the Proact Stadium by Chesterfield Borough Council was due to administrative matters as opposed to any concerns over practical issues.
After carrying out an investigation, director & company secretary Ashley Carson said: “The inspection was carried out in 2015 and certain observations were reported, namely the lack of paperwork and control systems.
“It appears that these actions were never undertaken by the previous manager and our current conference & banqueting manager, Peter Clarke, was not aware of these outstanding issues until he was approached at this year's inspection.
"We have subsequently been downgraded and now three months have elapsed we can re-apply for a review. All procedures have been put in place - which included keeping a record of fridge temperatures and other similar procedures - and I am absolutely confident that our status will be restored.
"I would like to stress that the downgrade was nothing to do with the overall hygiene of our kitchens, which is absolutely perfect."
