Certified food grade epoxies are used in industry all the time; in fact, some wine is aged in epoxy-coated concrete tanks, and the inside of soda cans these days includes a thin layer of food-grade epoxy.
I will not fault anyone for not believing the certification, but I would personally want to see a more authoritative source than an undated ceramics FAQ. But this is just personal style! Being suspicious of regulatory thresholds is prudent.
(And this FAQ has me wanting to revisit my priors and research this a little more specifically, because its assertions are plausible, but need sources or explanations or dates, for cross-checking. Food-grade epoxy I believe in would be a handy thing to have exist; I do have some certified food grade epoxy in my garage that I haven’t used for anything yet and I’d dislike downgrading it to just “epoxy.”)
No worries, with Claude's assistance I came across the FDA's Title 21 chapter 1 subchapter B, specifically 21CFR175.300. You're welcome to see what the US government has to say versus some random ceramic site.(edit:tl;dr safety-tested food safe epoxies exist)
