Therestaurant’s management reported that four employees had beenill with the “stomach flu” on Thursday, August 9, 2018 and thatthese employees were still out sick and had not returned to work as of August 17, 2018.

All five cases had been hospitalized. LCDHE staff conducted a third site visit that afternoon, and the establishment was requested to voluntarily close and discontinue all food preparation and sale of food; it closed late that afternoon.
