Yeah… decades ago when I was a socially awkward teenager, I actually was called out for that usage by people who were definitely not terminally online (hard to accomplish via dialup)…. and then I reflected and made a point not to do that anymore.
If you don’t get called out irl for that, this probably is primarily a reflection of the culture of the people you are associating with.
While freezing should kill multicellular eukaryotes (worms or other parasites), bacteria are pretty hardy, even to things like freezing. Plus, even when they aren’t, they make up for it in numbers… if you kill 99% of 10 million bacteria, you still have a hundred thousand that can subsequently repopulate if they are thawed left to grow a bit (even in the fridge). I’m not sure about these Vibrio strains, but the infective dose of some E. coli and Salmonella strains is measured in quantities less than 1000 bacterial cells.
Edit: reading a bit, probably this won’t be doing much growing at fridge temperatures (prefers warm water after all), however infections have been reported from oysters that were tested at about 900 cfu/gram of meat, so it might take (coincidentally) about a hundred thousand bacteria to cause an infection (~10g/oyster * 900 cfu/gram * 12 oysters or so). This isn’t very much… you probably have at least 1 to 100 million cfu/g of various bacteria on chopped lettuce, for instance.
