They’re only correct because they’re referring to a very specific situation that, for all intents and purposes, is completely wrong for any situation the average person will encounter.
So no, they’re wrong from a consumer perspective but right in factory conditions. So no matter what their professors say, don’t listen to this person because you’re not cooking in factory conditions.
I meant, out of context, that listening to your professors rather than internet randoms is the correct position to hold.
Yeah, I don’t disagree with that so long as the particular context is included when being passed off as normal in specific conditions. It was not mentioned that the professor stated this was for mass production and the comment was provided in a context that invalidated what they said. In context, without the edit, the professor’s advice is immaterial to the discussion and only serves to spread misinformation on proper hygienic practices.
But to the overall point, this is why you don’t listen to random people on the Internet! Sometimes you get told facts that are only true for very specific edge cases that are bandied about as general advice with the weight of ‘i have a degree’ as confidence even though the advice is objectively wrong in the provided context.
