I’m not a doctor, but some quick googling indicates that trichinosis symptoms start after a few days of being exposed to the worms, while scurvy symptoms show up after a few months of vitamin C deficiency[0].

I’m pretty sure I - as an ignorant person in this area - could figure out if people around me sometimes ate something, and then got sick within a few days, that maybe I shouldn’t eat that thing.

I doubt I’d be able to figure out that I should eat something on the basis of people getting sick after not eating a whole bunch of things for a few months.

0 - at least one source I found claimed scurvy symptoms could show up as soon as one month after “severe” vitamin C deficiency, but that “more noticeable symptoms would appear later.
