This happened to me about 5 years ago. Wasn’t too bad. Just had hives and awful gut pain. Enough to make you not want it but nothing life threatening.
Since I’ve figured it out, I’ve had beef or pork accidentally maybe two or three times. Feel awful for about a day.
I don’t miss red meat too much. Thinking about going full vegetarian.
I lived adjacent to a neighborhood like this. It was much quieter than middle aged neighbors with Harley’s. Little Cessnas and Pipers are not that loud.
