Listeria Contamination Shuts Coco & Carmen Amid Extensive Sanitation Efforts

The luxury restaurant Coco & Carmen in Stockholm has been closed as authorities conduct extensive sanitation following the discovery of a listeria outbreak affecting numerous guests. Environmental tests revealed listeria bacteria on approximately 25 surfaces and food items within the restaurant's kitchen, prompting a thorough cleaning process.

Between September 23 and 27, over 100 guests reported symptoms of gastroenteritis after dining at Coco & Carmen, with up to 450 patrons potentially affected, according to the Stockholm environmental administration. Of those exposed, 13 cases of listeria infection have been confirmed, including four serious cases resulting in sepsis. Approximately 150 individuals sought hospital treatment in the region, though there were no hospitalizations by Monday afternoon.

Authorities conducted about 50 tests at the restaurant, finding the bacteria on various work surfaces but not on certain food items such as shrimp, vanilla ice cream, or fish counters. In response, the restaurant discarded all food products and disinfected the kitchen, dining areas, and restrooms with a hydrogen peroxide aerosol disinfectant. Cutting boards and contaminated foods were also removed to prevent further spread.

"We are waiting for the environmental authority’s full report before planning our reopening," stated restaurant owner Joakim Almquist. The reopening timeline remains uncertain, as new menus and fresh ingredients will be necessary once the premises are declared safe.

The investigation into the contamination source continues, with ongoing tests of unopened food packages and surfaces. The restaurant’s comprehensive sanitation is part of efforts to eliminate the bacteria and reassure customers about health and safety.

This outbreak highlights the risks listeria bacteria pose in food service environments and underscores the importance of rigorous hygiene and monitoring practices to prevent public health incidents.
