The Wood County Health District, along with representatives of state agencies including the Ohio Department of Health, have been investigating the outbreak since June 9.
Investigators are interviewing patients who have become ill about the foods they’ve eaten and other possible exposures to the bacteria that causes the disease in the week before they became ill. They’re also interviewing staff and inspected Heritage Corner’s kitchen and other facilities.
The illnesses began on May 24, the health department said.
While the investigation continues, the health department has advised Heritage Corner to close common areas, including the dining room, and to thoroughly clean and sanitize the facility, as well as reinforce hand-washing procedures. The health department has suggested Heritage Corner serve meals in “take-out” containers that can be taken to residents’ rooms.
