I got this about 15 years ago after cleaning up the mo-in-law's property and getting bit by multiple ticks. Don't have it super bad and the worst reaction was to a ham made from a home raised heritage pig. Passed out twice with anaphylaxis. I go easy on the mammalian meats now. Got meat goats as they're super lean and it's a type of fat that does it. Recent strong reaction was to some sausage, bun sized. Thought it was odd and then looked at the package. Made from heritage pork.
That is something else. Just because it is heritage pork does not mean it is organic/natural. My family raised grass finished Angus beef for years. We ate all we could and sold the rest. McD’s and other fast food chains messed me up when I ate their crap.
I eat wild pig all the time and store bought farm pig will mess me up. I have been buying paddock pigs from the local Mennonites lately, good stuff. (and chicken and rabbits as well).
