Food Safety News reports that Massachusetts state and local health department officials are investigating 19 Salmonella cases linked to a restaurant in Holyoke,  Brian Fitzgerald, Holyoke’s health director, told a local TV station that officials were trying to figure out why people were apparently sickened after eating at the Delaney House in Holyoke between Nov. 11 and 15, 2014.

Investigative reports from the Massachusetts Department of Public Health indicate that 19 confirmed Salmonella cases and additional potential cases were traced back to 10 different events held at the Delaney House.

The restaurant has not been shut down, although the state asked local health officials to order the management to comply with several alleged food code violations.

Five food handlers and one non-food handling employee at the restaurant also tested positive for Salmonella. Some of the infected food handlers reportedly worked at events outside of the Delaney House, including the Log Cabin, a take-out restaurant, and various catered events.
