This is because most people don't wash them frequently... if at all.
As the commenters noted, this study was paid for by the same people who make plastic bags, and who have a vested interest in keeping people from banning them in, say, California.
However, as a political ploy, this one fails miserably. First, because it's easy enough to remove the germs just by washing your bag, as the study showed. Second, because it's equally easy to prevent cross-contamination by, say, designating some bags to hold meat and others to hold fruit and vegetables - a step so basic, I don't know why some people don't do it! Third, because you should always wash your food before you eat it, or cook it at high enough temperatures to kill anything, or both. And fourth, because people clearly aren't dropping like flies from their unwashed bags, even if by rights they really ought to be.
So, um... I'm going to do some laundry soon :)
