I've been using garbage bags for more than 25 years. If there's something wrong with it, I haven't been told as of yet. Yes, I've heard rumors that chemicals from the plastic could permeate the meat, but for the short time the meat is in the bags, I'll take my chances. I figure it's better than the alternative of dirty meat and dirty clothes, backpacks, and tents. I like to keep the blood off my pack and clothes because I don't want to draw bears in while I sleep in the middle of the night. I'm not afraid of the dark - I'm afraid of what's in the dark that I can't see.
