I remember when I was a kid back in the 80s, they had a brief show where kids could show off their inventions and this one girl came up with a type of edible tape you could use to do things like hold burritos together. I still think that's genius. Of course, it never became an actual product.
I have no idea if they still do it, but a decade or so ago it was all over the internet that a Brazilian fast food company had started using edible wrappers and made a marketing stunt out of it. The chain was apparently "Bob's".
Why would there be a warning unless people were eating them? Why would people eat them unless they were delicious? It's the forbidden fruit all over again.
Weren't people in 1980 still burning leaded gasoline, flicking lit cigarettes out of car windows, placing kids unprotected in the backs of station wagons, and serving Big Macs in foam containers?
Even if there is a rash of pika in 2023, I'd say we're still far advanced
