none of these things bother me. who cares how dirty the chicken is, once it gets deep fried all the germs die. beatle in the salad? doesnt bother me, he was hungry too. wood pulp is probably good for you so I dont mind that either. The fact that hotdogs are made up ground up leftover parts doesnt bother me either, and I KNOW there are rats and stuff like that that end up in the grinder, big deal.
Once things like razor blades and syringes start showing up in food is when I'll care about what I eat.
