On Feb. 14, CBP officers in Port Huron, Michigan referred a Canadian mail truck for an inspection in Marysville. During the operation, a shipment listed as an "antique teaching specimen" was targeted.
In a release, CBP said that upon opening the shipment, officers found a human brain specimen inside of a clear glass mason jar.
There was no paperwork or documentation supporting its lawful entry into the country.
On Thursday, a U.S. Border Patrol agent explained why someone may have been traveling with the brain...
April Donahy said, "It is possible that these items could come in for research studies or there have been times where organ donors. We will receive organs that can be transported across the border, but that is usually coordinated in advance with the proper permits."
CBP agriculture specialists in Port Huron are currently in contact with the Centers for Disease Control and Prevention regarding the brain specimen.
CBP said the shipment originated in Toronto and was on its way to Kenosha, Wisconsin.
