CDC reported 20 cases per year in US from 2008 to 2012. Used to be 400 cases per year. Still about 10,000 worldwide now. Modern pig farming has eliminated much of the exposure but you can still get it from bears, wild pigs, and those animals that eat them.
Freezing kills them, as does cooking to temp above 160.
Meanwhile you are not at risk with modern raised pork in the US.
I still don't like it.
PS. YD I'll bet we could find some of those spirals in your muscles from your early day binges. Its a cumulative thing.
