I have seen a post on how to keep roaches, etc., away, but let's say I did see a cockroach on my kitchen counter, and it did crawl on surfaces and food (let's say, some avocadoes that were out, ripening, as well as some Nespresso capsules). What might be a good way of cleaning food like avocadoes that may have been contaminated by the cockroach, but that we would still like to consume safely, if possible? How about Nespresso capsules?
In both of these cases, we don't actually need to consume the surface (of the avocado, of the capsule ..) touched by the cockroach, but wouldn't like to spray any kind of toxic substance on them nevertheless.
I found, in this healthline article
According to the United States Environmental Protection Agency (EPA), cockroaches carry bacteria that, if deposited on food, can cause salmonella, staphylococcus, and streptococcus.
According to the World Health organization (WHO), cockroaches have been known to play a role as carriers of intestinal diseases, such as dysentery, diarrhea, cholera, and typhoid fever.
