Imitation vinilla hasn't been made that way for decades. You almost certainly never eaten anything with it in it.
Less than 250 lbs of the stuff was consumed in the US in 1987 and it's only gone down from there.
It's actually significantly more expensive than sythensized alternatives like vanillin since there is basically no commercial beaver trapping anymore.
Decades before this was something I could scare the girls in food class with, it was already not true.
