Don,
I live in South Texas and as you know it's pretty hot down here. Anyway, I once I shot a rabbit (cotton-tail) in the summer time (August) and intended to eat it. However, when I skinned it it was full of worms between the hide and muscle tissue (they were fat white ugly worms).
Needless to say I didn't have much of an appetite after seeing that. That was the first and only time I had ever seen worms in a rabbit and I had killed and eaten plenty of rabbits.
When I mentioned this to an older friend of mine he suggested that I only kill rabbits in the months that have the letter "R", otherwise it's too hot here and they get worms. I followed his advice and havn't found any more worms in my rabbits.
I guess you could kill one and check to see if it has worms. If it doesn't, then you could eat it.
Good Luck.
