I’ll bet artificial turf, much like a plastic cutting board, is a breeding ground for all sorts of nasty bacteria. Who knows what constant irritations that never really heal could result from that?
It could be a “breeding ground” especially at an indoor stadium, I would think, but outdoors probably not as much.
Most places sanitize the turf once a year, to prevent spread of staph infection.
Probably no more than good old fashioned dirt, mud, grass, grubs and worms.....
I doubt it. Maybe in indoor fields, but if its outdoors, sunlight is one of the best antibacterial agents known to man.
Turf burns are nasty, and readily infected. At least that is how it was when I was in college. We played intramural football in long sleeves and long pants to keep from getting ground up on the turf.
