MIAMI (AP) — Scuffles broke out and people waiting in long lines fainted from the heat, causing officials in South Florida to cancel a food voucher giveaway for people affected by Hurricane Irma.

On Saturday, the Broward Sheriff's Office canceled Sunday's voucher giveaway in the county due to "safety concerns and overwhelming response."

In Miami-Dade County some 50,000 people were already waiting in line when the doors opened at a Miami park facility on Sunday morning, Ofelia Martinez, a site manager for the Florida Department of Children and Families, told the Miami Herald.

The state agency says more than 1.1 million people applied for the program, which provides vouchers that can be used a grocery stores.

It was unclear whether everyone who showed up Sunday got a chance to apply.
