I don't believe that's true. You are probably thinking of the fact that egg shell becomes more porous when washed - if an egg is dirty or contaminated, washing it increases the chance for bacteria to get inside. I personally try when cracking eggs to minimize the amount of exterior shell that the egg touches, but I'm not sure how much that matters.
Eating raw or undercooked eggs will always be a higher risk. Further reading:

The first link works fine for me on mobile web. We are on the same instance so that may be the fault of the app you are using to browse Kbin.
And I included the second link because it's a nice fact sheet of egg myths, I'm aware that eggs are handled differently there
Do you have any sources for this claim?
My understanding is that while removing the bloom does make it easier for bacteria to penetrate the shell, because that's done just before packaging, the overall risk of contamination is lower. It's important to note that if the hen is infected there's a possibility for salmonella to be inside the egg regardless.
