The question is in the title. By limits I mean, for example, should food preparation questions be allowed even though those are more directly on topic in Cooking.SE?
This question was prompted by this question and the ensuing comments.
Condensed from comments below a more specific main-question related post, this seems to be the emerging opinion:
While we strive to be much stricter than before on posts related to food in terms of nutrition, we can be more accepting on food safety.
Food-safety related question are on-topic in principle.
Mainly we want questions more clearly dustinguishable from basic CookingSE and basic BiologySE.
But it's kind of a slippery slope and the questions would have to be very narrow. For example, "To what temperature do I need to cook chicken?" is a food safety question, but it's also clearly more appropriate on Cooking.SE. "Which bacteria tend to grow on chicken under what conditions?" goes to BiologySE.
Our turf: "How high is the epidemiological impact or risk of salmonella infections? How is this best prevented or treated?"
That would mean that food preparation questions are under special scrutiny.
But as long as the primary intent and scope of the question are framed from a public health, disease prevention perspective – and of course the question presents prior research from scientific-oriented sources, instead of e.g. house-keeping or cookbooks – the it looks more like a good fit for this site.
Questions reviewers or voters might consider in evaluating such a question:
One real life xample from main would be:
Discussed in the medical literature, no good match for cooking and better fitting on MedSci than biology?
……to be done: more or better examples, questions to evaluate where a positive answer leads to negative assessment……
