I have seen cloth bags put on the grocery counter, that I would not want pig feed put in them.. looks like they have never been washed.. and then washing does not get rid of lots of germs..and etc..I worked in a large grocery chain when plastic bags were forced upon us.. and customers wanted to know if they could bring in their used paper bags, and the answer was no as they would carry germs..
So true Joanne. Also, new paper bags, in grocery stores were phased out as the norm and are given if a customer asks for them, because they carry roaches and roach eggs home.
