National borders are demarcated in many ways, from walls, fences and blockades to more subtle divisions of language, custom or religion.
These divisions can sometimes show up in unexpected ways — such as in the color of the chicken on your supermarket shelf.
In the United States, chicken appears white because it’s subject to a chlorine bath to kill microorganisms such as salmonella. But that’s not the case in the European Union which, unlike the U.S., has strict standards on every step of the production process, explained Professor of Anthropology Thomas Wilson. EU chickens don’t undergo the post-slaughter acid bath of their American counterparts; as a result, their flesh appears pink.
But when a country leaves the European Union — as the United Kingdom did early this year — standards and trade agreements change. American chicken, prohibited by the EU, is now potentially eligible for import.
