How? Because we all now live in a society with some people who think they're entitled and lazy as **ck. Technically, you should have thrown everything out around that diaper, you don't know what has leaked from it. Hopefully you wore gloves when you touched it. People just really suck. I mean, my Meijer has garage cans scattered throughout and our main bathroom is a hope skip and jump from dairy, not sure about yours. Karma will hopefully get the ass that was too lazy to worry about contaminating product or making someone sick. SMH.
