Detroit Free Press reports that local health authorities are investigating reports that at least 30 people attending a banquet last week at Detroit’s Roostertail banquet facility got sick afterward with nausea, vomiting and diarrhea, the state health department confirmed Wednesday.

The reports came from a banquet for 370 people last Thursday, said Lasher.

The state Department of Agriculture, which collaborates with the state health department on food safety issues, alerted the state health department about at least 30 reported cases of food poisoning, Lasher said.
