It’s incredibly frustrating. The pret case often gets brought up- but she would have suffered the allergic reaction wherever she was given she ate the baguette which had been mislabelled- no airborne exposure, no airline food involved, no other passengers, no peanuts
the CAA has had guidance for a long time saying the announcements or restrictions are ineffective, and yet they persist. There was also recently a review posted saying the same thing. And yet they persist.
these kind of threads often end up with lots of pearl clutching and hand wringing posts either from white knights or people with loved ones with allergies, essentially strawmanning “why is your snack so important” or offering up “evidence” of low quality for example suffering mild symptoms which could equally be anxiety or other presentations, and then finding someone 10 rows away had eaten a snickers around the same time. There is never any actual objective evidence presented and yet the scientific studies have never been clearer
I will be very interested to see what you are able to come up with- I suspect not much but effectively crowdsourcing the literature review seems like a smart move
