> It could be cold-evolved bacteria. But it could also be that now, we are exposed to many orders more bacteria, than before. I'm not a doctor but I do gravitate to reading about gut bacteria. It's fascinating. It also seems to be fragile, there's a delicate balance. With that said, aside from some bacteria evolving to survive refrigeration, perhaps there is also "converse" bacteria that did not evolve? So the balance that we would get from local non-refrigerated meat doesn't really exist now? Freezers are changing the bacterial composition (as opposed to say the chemical composition). It's not what we're getting more of, but also less of. Maybe?
