You said "I'm not afraid of parasites from beef"...
I don't mean to be a smartass or anything, but that just sounds "plain crazy" to me.
I went to a steak place here in Austin one time, that served rare beef, and there was a disclaimer warning on the menu. It said eating rare meat can cause diseases, and you must do so at your own risk. Once again, I must ask, are you pulling on our legs for some reason? Would you play with a scorpion and not expect to get stung? I am confused.
