The same people who say that are the same ones who say antelope is the worst game meat. The main thing with antelope is to bring lots of latex gloves. I for one am not as cautious as I should be with protecting myself when dealing with animals, but gloves for antelope isn't just to protect you from pathogens. They have a very strong scent gland not only on their hock like most animals, but also there neck and horns. Those black marks on the face are a result from these glands. Where people screw up with antelope is they take their grip and grins then jump into removing the skin as fast as they can because thats what you have to do with antelope, which is true. What people don't think about is they just had their hands on the neck and horns for their pictures. They got all that antelope gland on their hands, then the rush to get the skin off so it can cool and spread that gland all over the meat.
I like to take plenty of gloves and a bar of soap. Take your pics, then wash your hands. Next put on gloves then start taking care of the gutting and gilling. If you touch anywhere near the glands (head, neck, or hock), change your gloves. Its nice to have someone with you so the can position the animal for you so you don't have to risk spreading touching a gland. Although an antelope gland isnt a bad smell (reminds me of past hunts and I love it), it doesn't taste all that great.
