Leaving Trash outside condo doors

Has anyone ever seen any studies on the hazards of leaving trash (even in plastic bags) outside condo doors.....only to be picked up by the owner at a
later time and taken to the trash bins? I am attempting to find some studies that MIGHT have been done on this subject.

All it takes is some common sense. You don't need any studies to prove that it's not a good thing.

You live in FL - trash left outside attracts everything from wild animals like raccoons, armadillos and possums - even bears, in some parts - to rodents to domestic animals like dogs and cats that can be harmed by eating what they find in the bags. Many communities have rules against leaving bags of garbage outside without being in a can and if you're thinking of passing such a rule I don't think you need studies to prove that it happens.
