>>24170726Bleaching is a fairly old concept, as is the idea of detergents - soap was used by Sumers, and Pliny the Elder wrote about using different kinds of plants (and their ash) to clean clothes. Before chlorine-based bleaching agents were invented, people use different kinds of methods to bleach fabric, which was time-consuming but still effective. As such, /meat/ most likely knows about procedures like that, although I don't think we actually need bleach for cleaning.
As for /meat/ pathology, the predominant idea is probably a variant of the age-old miasma theory. Their experience of dealing with corpses and other infecting agents meant /meat/ likely will know the basic miasma theory is insufficient, so it is probably supplemented by the idea that some kind of pathogen can enter you even without you breathing in the miasma. A RL proponent of that idea is Charles de Lorme, who is probably most famous for inventing the suits in picrel, which is the reasoning behind the all-covering suits in addition to the herbal mask. Combining that with /meat/'s existing idea of cleaning things to prevent infection to open wounds (which they cause a LOT of), /meat/ might actually end up being quite advanced in epidemiology (at least compared with proponents of basic miasma theory and humoral theory, or just attributing it to divine punishment).
