Restaurants and bars in Michigan will be required to record the names and phone numbers of all of their customers starting Monday.
"All dine-in food service establishments must maintain accurate records of the names and phone numbers of patrons who purchase food for consumption on the premises, and the date and time of entry," the new order reads.
The Michigan Department of Health and Human Services introduced the new rule on Thursday "to aid in contact tracing and case investigation efforts." The order was issued on the same day Michigan set its daily coronavirus case record at 3,675, with 41 deaths.
The new rule also limits non-residential indoor gatherings without fixed seating to 50 people, and individual tables to six people.
"We are taking targeted actions via the order to address areas that are particularly severe sources of spread, and we are issuing guidance that is a very clear road map for what we need to do bring cases down," said Robert Gordon, the director of the Department of Health and Human Services.
