Is this really a risk in practice though? I can't find any cases of this actually happening on the CDC's botulism site: https://www.cdc.gov/botulism/surveillan

might become a risk if it lies around defrosted for many hours.

I am somewhat skeptical of this as well. It's not uncommon to hear of someone having eaten something "bad", but that can be the result of many pathogens and with regards to botulinum, the article gives a data point: > In the UK, between 1990 and 2005, there were 5 reported cases affecting 6 people and causing 2 deaths, meaning that you were 15 times more likely to be hit by lightning.

  That data is clearly only reporting very serious cases though, since one third of them died. Food poisoning is much more common than lightning.

    > Food poisoning is much more common than lightning. I said as much. The question is whether botulism is more common than lightning. Food poisoning is not uncommon, but can be caused by many pathogens, for example E. coli. Given the fact that we have a common illness but very few confirmations of C. botulinum as the cause, the question stands whether this is really a risk in practice.

it's a risk for certain fish and if you defrost the fish in the fridge for days... but as it stands botulism is not a very common thing to worry about in modern society. there are about 200 poisonings per year in the us. a lot are junkies using shared and dirty needles... babies eating honey is another large one. maybe about 20-50 per year in the us is an adult getting food borne botulism. in any event yes it is risky to defrost the fish in a vacuum sealed bag but only if you thaw it for a few days or more like that. 50F fridge is about 2 days and 45F fridge is a few more days before there is growth: https://www.riskyornot.co/episodes/34-thawing-frozen-fish-in-vacuum-packed-bag https://www.riskyornot.co/episodes/34-thawing-frozen-fish-in... Fwiw i just thaw it the day i use it in cold water for < 1hr and it's almost certainly fine to use that day.
