Copenhagen - Dozens of guests at a top-rated Danish restaurant were recently hit with a stomach virus that causes vomiting and diarrhoea, the Danish Food Administration said Friday.

“We are really sorry,” said Peter Kreiner, chief executive of Noma, which has two Michelin Stars and has been named the world's best restaurant for the last three years by Britain's Restaurant magazine.

An employee who did not show symptoms associated with the stomach bug, also known as gastroenteritis, was the likely carrier of the virus.

Kreiner said in a statement that the restaurant was discussing how to compensate 63 guests affected during February 12-16 and had taken measures to disinfect the kitchen.

The Danish food agency said it has for the time being dropped its elite Smiley designation for the restaurant. The Smiley-scheme introduced in 2001 helps consumers monitor how stores and restaurants comply with food regulations.

Food lovers often have to book months ahead to taste dishes created by chef Rene Redzepi and his staff. - Sapa-dpa
