Uh-oh. The Waggoner says beef and beef by-products can enter the U.S. Customs officers at the Seattle Boat Show said no.
Don’t bring beef or anything that has beef in it into the U.S. This includes canned food such as the ever-popular but never opened cans of Dinty Moore stew.
Note that food and other import restrictions are apt to change at any time, with no announcement. It’s a good idea to check with Customs prior to your trip to avoid unpleasantness.
