Suspend School Meal Debt Act This bill directs the Department of Agriculture to reimburse each school food authority and local educational agency participating in the National School Lunch Program or the School Breakfast Program for unpaid meal fees owed to the authority or agency as of the date of the enactment of this bill. The bill also prohibits each school food authority and local educational agency from collecting unpaid meal fees or using a debt collector to collect such fees during the COVID-19 (i.e., coronavirus disease 2019) public health emergency. The prohibition ends 30 days after the date on which the public health emergency is terminated.
