Eggs can be pasteurized- aka heated to kill off bacteria such as salmonella - without cooking them. From a quick Google, in the US and Japan it should be standard to make this dish with such eggs as to be safe to eat. I can’t speak to Brazil’s food safety standards though- the chances of using pasteurized eggs could be a lot lower, however if it’s a Japanese export/import, Japan takes such safety very seriously, so it’s likely to be safe.
