The US washed its eggs to reduce rates of salmonella, it is literally in the article you linked to. That it was effective can be seen by incidence rates. The difference in salmonella rates between e.g. the US and many European countries is almost perfectly accounted for by the difference in handling eggs. With a little googling you can find plenty of papers on the subject.

The OECD and other sources rate the US, Canada, and Scandinavia has having the highest food quality and safety in the world. It goes beyond salmonella, they apply the same zealous cleanliness requirements to many other food products. This isn’t controversial, it is on the OECD website among many others.

Famously, many EU food products could not be imported into the US unless they were processed in Scandinavian food processing facilities, because other European countries had facilities that did not meet US standards. It was good business for countries like Denmark for a long time.
