A human brain was found in an international mail shipment at the Blue Water Bridge at Port Huron last week.
On February 14, U.S Customs and Border Protection (CBP) officers referred a Canadian mail truck that had crossed the bridge, for inspection at the Centralized Examination Station in Marysville.
A shipment manifested as an "Antique Teaching Specimen" was opened and found to contain a human brain specimen inside a clear glass mason jar.
In a news release, CBP said there was no paperwork or documentation with the shipment supporting its lawful entry into the United States.
The shipment originated in Toronto and was destined for Kenosha Wisconsin.
Area Port Director Michael Fox said there are strict controls on such items.
"Individuals looking to import shipments such as this, need to remember that the Center for Disease Control and Prevention has a strict Import Permit Program that must be adhered to," said Fox. "This is just another great example of just one of the many things CBP officers do to protect our nation on a daily basis."
CBP agriculture specialists in Port Huron were in contact with the CDC regarding the brain specimen in relation to import regulations for infectious biological agents and infectious substances, and directives for final disposition of the specimen.
