I was worried it was going to be like the salmonella thing where it turned out washing a chicken* is terrible advice because it spreads it everywhere and so it turns out that every time I wash my hands after handling deliveries, I'm now covering my kitchen with Covid sauce. I'm very happy that's not the case.
* I've never washed a chicken, but I've definitely seen and heard the advice before.
