Piglets crowd a stall at the H.C. Daniels hog farm in Drahnsdorf on April 28, 2016 near Golssen, Germany. German hog farmers are exporting pork meat successfully to Great Britain and undercutting British farmers, in large part because British regulations on how pigs may be raised are stricter than in Germany, meaning British pork is more expensive.

EU membership means Great Britain cannot impose tariffs on German pork. Photo Credit: Carsten Koall / Getty Images.
