From avocado toast to margaritas, the United States is heavily reliant on Mexican imports of fruit, vegetables and alcohol to meet consumer demand. Nearly half of all imported U.S. vegetables and 40 percent of imported fruit are grown in Mexico, according to the latest data from the United States Department of Agriculture.

Americans would run out of avocados in three weeks if imports from Mexico were stopped, said Steve Barnard, president and chief executive of Mission Produce, the largest distributor and grower of avocados in the world.

“You couldn’t pick a worse time of year because Mexico supplies virtually 100 percent of the avocados in the U.S. right now. California is just starting and they have a very small crop, but they’re not relevant right now and won’t be for another month or so,” said Barnard.
