As this piqued my interest I tried to find data but it is complicated mainly by the fact that vaccination rates are vastly different. If we go by raw, reported Salmonella cases the American approach seems to be significantly safer, but then again we seem not to have a good idea about the unreported cases. It probably doesn't help that it is a politically charged topic too - see "Eggwina" in the UK [1].
