Sometimes meats leak and if it gets on veggies, there is the possibility of getting salmonella or some other kind of infection. People who have to drive far like their cold stuff grouped together so it keeps the temperature better, and it's quicker (e.g. less energy waste) to load up the fridge from just a couple of 'cold bags.'
Still, I personally don't find it a big deal and have never gotten food poisoning from the chicken being bagged next to the lettuce. It probably helps that all the produce is in plastic bags anyway so it doesn't touch the meat -- you don't just lay that stuff bare on the conveyer, do you? And if I were making min wage at a grocery store still, I care more about the grumpy customers getting out of the store in a timely manner than your picky bagging sorting preferences.
