Short answer is, we don't know yet. In the issue, the Hunters admit that they don't know what effect that eating the "tainted meat" will have on them. Dale said what he said to scare them, but he probably doesn't know 100% either. So it might infect them, it might not. We'll have to wait and see.
For the record, TWD established that dying at all with your head intact will cause you to turn. The risk of a zombie bite is that you might die from infection, but that's pretty much it.
