my courteous boss informed us at lunch that his friend had told him that there was something wrong with the pork in Beijing right now, and we shouldn't eat it. That was it. No more information. No explanation of what was wrong with the pork, what would happen to you if you ate it, when it would be safe to eat pork again, nothing. Thanks, boss's friend. Now I am never going to be comfortable eating pork here again. And i've got this carton of leftover suan tai rou si in my fridge that had been thinking about all day. darn!
