> In what contexts is lying to the public a crime?
This feels like a disingenuous question. I'm not a lawyer, but I'm pretty sure that claiming X isn't toxic, when you know that it is dangerous. Public health, frequency, scale of impact (more often, who is impacted that has resources to compete in court) et al are all considerations.
Humans act in their own self interest. Relying purely on individual self interest is a degenerate approach in public health issues. One of the many purposes of government, is to act in the collective interest. eg Typhoid Mary

If all you have is vibes, then it's a pretty legitimate question.

That's exactly not how the legal system is supposed to work. Bending the rules just because some defendant is particularly unsympathetic is exactly how you get politically motivated prosecutions and kangaroo courts.
