GOLSSEN, GERMANY - APRIL 28:  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. Supporters of Great Britain's departure from the European Union, or Brexit, cite cheap imports of pork as one example of why Britain should leave the EU. EU membership means Great Britain cannot impose tariffs on German pork.  (Photo by Carsten Koall/Getty Images)
