Beginning Tuesday, all food-related businesses across the five boroughs will be required to place their trash bags in containers on the street in order to curb the rat population.

The Department of Sanitation proposed the rule change in May, and it was officially endorsed by Mayor Eric Adams and Sanitation Commissioner Jessica Tisch in late June.

The new rules specifically apply to businesses involved in handling food waste, including restaurants, delis, grocery stores and bodegas. It will also apply to all chain businesses with five or more locations within the city.

The Sanitation Department said there will be a one-month grace period where it will issue warnings to restaurants before fines begin.

Tisch joined "Mornings On 1" Monday to elaborate on the rule change.
