I was just remembering some recalls somewhat recently of big bags of frozen fruit in stores like costco. And i was wondering, how can any bad bacteria survive the freezing long enough to make people sick by the time they buy and eat the fruit? Shouldn’t the freezing process kill practically everything?
In: Biology
No, freezing doesn’t actually kill all microbes, it just stops their reproduction meaning they don’t multiply. But many bacteria can survive in that “cryogenic” state for a long while and then come back to life when they warm up again.
They’re basically so small that as long as the freezing doesn’t make their cells burst, they will survive.
