Oddly enough, it's easier to get lutefisk in communities here in the US with Scandinavian populations that in Scandinavia itself.
They're not so broke anymore that they have to eat fish preserved with lye, it's mostly served here on a dare...
Just as we no longer have to eat jerky, because we now have refrigeration to keep meat from spoiling. The lye killed the bacteria that would have caused decay and preserved the fish.
Now, jerky and lutefisk are specialty items instead of regular fare.
