What do you mean by "inordinate"? Reason as a main source of social norms is a much later ideological invention, usually considered a result of the dominance of the roman catholic church and its adoption of aristotelian philosophy.
You're still defending possibility as such, and not arguing for relative likelihood. I find the lack of anchoring in early judaic society suspicious.
If you read the Torah you'll find that it is not a collection of argumentative texts. To the extent that Leviticus makes an argument it stops at two criteria, cloven hoofs and rumination, without further explanation. This is also how more well-known early judaic legal norms were communicated, e.g. the noahide laws and the decalogue are presented as is without further argument.
The context of early judaism was also quite deadly in itself, people died all the time from a variety of opaque reasons. Figuring out that someone died due to some meat-transmitted parasite rather than a disgruntled shedim wasn't very likely.
The Torah is quite unconcerned with things like health or actions that are supposed to result in a long life, insisting instead that these things are decided by G-d. Dying isn't given a very prominent place in this early theology either, it just kind of shrugs it off with a vague idea about Sheol as a container for souls, in case they just don't stick around like some ancestral ghosts or something.
Pork was widely eaten at the time, so the "good heuristics for food safety" thing seems entirely useless to me. People already knew how to prepare pork and did it, and pork isn't particularly insidious, if kept in a warm environment it'll ward off your nose and taste buds in no time. Beef (and mutton) is more likely to trick you into eating it even though it has gone bad, and it also carries a risk of giving you parasitical or bacterial infections.
