My stomach squicks at meat counters in stores, I avoid meat markets, and I would not care to see a hunk of raw meat out in the open in someone's refrigerator. I am a grown up and were I a guest, I would deal, silently. But I honestly wouldn't want to put my food in there or use that refrigerator, so I would, without comment, make arrangements that made me comfortable. Coolers are cheap. So is ice.
I absolutely cannot imagine someone doing something to the meat in that refrigerator. What? Why?
Foods being marinated should be enclosed, not out in the open, I believe, from a culinary aspect. I suspect refrigerator funk. And I don't care for preachy anybodys, including other vegetarians.
