They're hard to find because most grocery stores don't stock them, but you can actually buy pasteurized eggs at some places in the states too. They pasteurize by putting the eggs in hot water for a few minutes, so it's a simple process that you could actually do at home (but getting it right is tricky).
I have a prairie oyster for breakfast sometimes: one unbeaten raw egg, a few dashes of worcestershire sauce, a little Tabasco, salt and pepper, and then you kindof eat it like it's a raw oyster. It's an acquired taste.
