Thank you for the translation note; it's really interesting.
True, why is she afraid of food poisoning, though, because the oyster is already cooked? I understand if it's raw.
Interesting shes Concerned about food poisoning in this case since it's more cooked than full on raw lol
Because if oysters and this is applicable to all raw seafood, if its contaminated beforehand, it might still give food poisoning. Also, certain foodborne bacteria can form spore and are not susceptible to heat, example like Staph. aureus.
Also virus like norovirus are quite resistant to heat as well. Again, this isnt just oysters, should exercise caution with other shellfish as well.
