Most are fine to eat. Sows are just as good as pork you buy in the grocery store. Occasionally you will find a boar that is rank. You will know it as soon as you get close to it especially down wind. There is not much you can do about it. It has abosultely nothing to do with how the meat is handled or processed, it just plain stinks to high heaven as soon as you walk up to it. We have killed 3 that were rank out of maybe 50 or so. They are not necessarily the biggest boars either. The last one I killed was 220# and was just fine with no odor at all. The ones we have killed that were rank were a 155#, 175# & 275#. We have killed many boars from 150# to 200# that were fine eating. If you do kill a rank boar and handle it without gloves, you will have a heck of a time getting the smell off your hands, I know.
