I've been reading up on salmonella - that's the reason we wash eggs and refrigerate in the US. I don't wash mine and do refridgerate. In the UK, they vaccinate so they don't wash/refrigerate.If you don't wash your eggs you don't have to refrigerate. Keep them in a dark cool place they will last six months or more. If unsure put them in water and if they float they are bad.
I'm curious though, what % of farms have salmonella? Is it just factory farms? What are the odds that my BY hens might get salmonella and pass it on?
