There are some foods that aren't legally available in Texas due to federal import bans. Haggis from Scotland, for example, is banned because of restriction on importing sheep's lung. The Kinder Surprise, the Italian-produced chocolate egg filled with toys, has been banned because of the choking hazard that comes from filling a candy with small plastic objects.
Via tjmwatson Haggis. If you want it in Texas, you've got to get your own sheep lung.
A lot of states have their own food bans, though. California has been dealing with a ban on the sale of foie gras since 2012, largely because force-feeding ducks and geese to produce extra-fatty liver is considered inhumane.
