In the UK, farmers are not required to give antibiotics to reduce salmonella. However, most buyers require "Lion Mark" certified eggs, which requires vaccination (not antibiotics!) against salmonella. Because of this program British eggs are widely considered the safest in the world. I will happily eat Lion Mark eggs raw.

I'm surprised that free market enthusiasts rarely talk about the Lion Mark, because it's great example of entirely private business (except for the government trademark enforcement) improving standards for consumers.
