Yes eggs in Mexico and eggs from Mexico are safe to eat and there should be no health issues.
Even though in Mexico they do not wash the eggs that is actually a good thing because when Mexico people do not wash the eggs that means that the cuticle and shell are left undamaged, functioning as a layer of defense against bacteria.
So the eggs in or from Mexico are likely safer for human consumption than any other eggs coming from places that wash the eggs.
Although even if the eggs from Mexico or any other place contained bacteria or Salmonella the heat from cooking the eggs will kill the bacteria and Salmonella.
So as long as you cook the eggs all the way through then you should not get sick from the eggs and should not get any Salmonella Poisoning from the eggs.
