There are hundreds of salmonella outbreaks in Europe every year, but also in the US. Salmonella is mostly fought in the animals rather than in the eggs. But both the European and American way of handling eggs works.
They'll last at least a month, some have even found eggs last in excess of 100 days, there have been rumours of a year but I've never seen it.
The problem with refridgerated eggs is that they don't tend to be as loose, this is fine for poached eggs but less fun for mayo or baking.
from that page: shelf life of a room temp egg is 21 days; for a refrigerated one it's 50 days. Eggs are washed to control salmonella (eggs are also somewhat dirty when laid, having likely touched poop). US started washing eggs in 1970. Japan started in the 1990's after a salmonella outbreak. Scandinavia also washes. Countries that don't wash-and-refrigerate can require vaccinating chickens against salmonella. It is also commonly recommended to wash unwashed eggs before cracking them.
The USDA claims the only countries that wash/refrigerate their eggs are the US, Canada, Japan, and Scandiland. The whole argument against washing the eggs is to protect against bacteria, salmonella among them. The thing they focus on primarily for the reason we still wash/refrigerate them is freshness. They carried out a study and found washed/refrigerated eggs were fresher after 15 weeks than those stored using other methods.
Statistically speaking, unwashed eggs are not "perfectly safe". It is the reason countries started washing eggs.

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.
The external cleaning process mandated by the FDA results in the destruction of the bloom, which leaves the eggs vulnerable to all sorts of nasty stuff. Moving abroad one of the weirdest things was seeing eggs, on occasion a bit 'dirty', stacked at room temperature for days to weeks. Turns out it's perfectly safe!
