Yes, considerably.

And in the US, from the article:

> ” Salmonella hospitalizes and kills more people in the U.S. than any other foodborne pathogen, with about 1.35 million illnesses, 26,500 hospitalizations and more than 400 deaths each year.”

US population is 330 million, EU is about 450 million. The difference in salmonellosis prevalence is huge.

The rate of infections are very diverse in Europe. In Scandinavia it is extremely low, they test the chickens several times during their lifetime and kills the whole flock if any of them is contaminated. Until they joined the EU all eggs were "washed" which removed other unwanted pathogens. The EU forced them to accept unwashed eggs and allowed them for the time being to continue selling washed eggs. Most other countries does not use such draconian methods to their farming and the washing of eggs removes a thin membrane which gives some protection from salmonella travelling between the eggs.
