Food safety officers from West Lindsey Council inspected the Gamekeeper pub in Gainsborough, on 4 July.
There was major improvement necessary in the management of food safety, which involves system or checks in place to ensure that food sold or served is safe to eat.
It also requires evidence that staff know about food safety and the food safety officer has confidence that standards will be maintained in the future.
The cleanliness and condition of facilities and building needed necessary improvements including having appropriate layout, ventilation, hand-washing facilities and pest control.
However, there was some good news as the pub’s hygienic food handling was deemed as ‘generally satisfactory’.
Greene King Pub Partners is the pubco's tenanted/leased arm which won Best Tenanted/Leased Pub Company at this year's Publican Awards.
The Morning Advertiser has attempted to contact the pub but has received no response at the time of publication.
Meanwhile, Greene King managed house the Tredegar Arms on Caerphilly Road in Newport, south Wales, received a zero food-hygiene rating and was required to make major improvement in its food safety management and food handling methods, just days after a new manager took on the site.
Inspectors from Newport City Council visited the pub on 17 July and found major improvement was needed in the hygienic handling of food, including preparation, cooking, reheating, cooling and storage.
Work was also found to be necessary in food safety that involved systems or checks in place to ensure food sold or served was safe to eat.
A spokesman for Greene King said the pubco prided itself on its normally high standards and apologised to customers for this “unacceptable lapse”.
It added: “As soon as we received the report from the council, we took immediate action to remedy the situation.
“We have invested heavily in our kitchen and now have a new manager with a wealth of restaurant experience who started with us this week.
“We are confident in the pub’s standard and are seeking a re-inspection as we hope to regain our previous five-star rating as soon as possible.”
