A McDonald’s in King’s Lynn is being monitored by environmental health officers after a rat was spotted inside the restaurant.

Video footage, circulated on social media, showed the rodent running along a windowsill inside its Hardwick branch on December 15.

McDonalds, which re-opened the branch this week, blamed an issue with a neighbouring property and said hygiene was of the “utmost importance”.

A spokesman said: “A rat ran through the front doors and was quickly contained in a small area away from the kitchen and removed. The restaurant was immediately closed while the issue was dealt with and remained closed while a thorough sanitisation process was undertaken. 

“Pest control was called to carry out a precautionary inspection and the environmental health office was liaised with.”

West Norfolk Council confirmed an environmental health officer had visited the branch on January 3. 

A spokesman said: “Staff at McDonald’s notified us of an issue at their Hardwick restaurant, which they voluntarily closed, and we have been visiting daily with their full cooperation. 

“We are satisfied the issue has now been resolved. We will continue to visit and monitor over the next few days.”
