But that still would not be food poisoning caused by leaving food unrefrigerated, as the other poster implied. It could indicate inadequately washed produce, but that is not at all what was stated.
True. Mostly people don’t have a clue what’s making them ill or where it came from. When people get symptoms of gastroenteritis they usually blame “food poisoning”.
My point was that noro is far more likely than food poisoning.
