I only added salt for taste. You can make these with meat-only if you want. As long as it is not cooked, meat won't go bad, only become high, won't it? I don't know about if it has had salt added or not though, but I only added the salt for taste, and it is raw himalayan pink salt.
I also didn't make these to store for a long time. I only made them because I don't like the taste of the ground grass-fed beef anymore, only the grass-fed steaks, but the only store I can find grass-fed steaks from has been out of stock for a while.. So I was looking for an alternative to still be able to eat grass-fed meat everyday.
If I was going to do it for storing meat, I probably wouldn't have added any spices or salt, because I wouldn't know how the spices and salt would react sitting around for long periods of time mixed with the meat. But I have thought I might possibly turn some of the grass-fed steaks, when I get them, into jerky for storage, because I also don't like it so much after it has become high, and would rather still be able to eat it even as dry dehydrated jerky. However, I also don't know how much nutritional damage that dehydrating does..
