For what I read , Covid19 can persist active in a common freezer for months or years (it seems pretty obvious: cold, humid...). My question does not regard only the currently active coronavirus at this posting date, but any.
So, I imagine that if the surface of a bottle or bag is contaminated, taking it, a month later will start the spreading mechanism, don't know, hands, surfaces, face, etc. And the virus will spread internally in the refrigerator, given that common refrigerators have channels that spill drops which flow through the cold and warm refrigerating sections. Or internal ventilators.
Under such perspective, a common refrigerator would act moreover as a Petri dish. Completely different from the rest of house surfaces, which would allow viruses vanishing way more faster.
If that is so, is it possible to clean a fridge from coronavirus? Do common refrigerators increase the risk of propagation?
