That's not the complete story of leg amputations.
Dale's was the 2nd amputation.
Allen, got the ankle bite early in the prison arc. They cut off his leg, but he died from the bloodloss, while I believe Dale survived because they stopped the bleeding quickly (think they did it in the infirmary, and I think they had the doctor from that town)
About the cannibals eating Infected Dales other leg, he wakes up and says "TAINTED MEAT! TAINTED MEAT!"
