Philadelphia's Mayor Michael Nutter is banning feeding large groups of homeless people in city parks.
The move is meant to encourage homeless outreach groups to distribute food indoors.
Nutter says the outdoor feedings don't help the homeless with either sanitary conditions or dignity.
"This is really an issue about food safety and public health," Nutter said.
The rule would not apply to family or group gatherings in the parks.
One volunteer who works with the homeless calls the measure a "clear violation of civil rights."
Violators will receive up to two warnings before getting hit with a $150 fine.
The ban takes effect in 30 days.
