Federal agents seized nearly six pounds of fentanyl at the Fort Street Cargo Facility in Detroit.
CBP officers were conducting inspections of inbound international mail when a K-9 alerted to the possible presence of the synthetic opioid.
A physical inspection of the package revealed multiple plastic bags of pills, which were identified as fentanyl through subsequent testing, according to a news release.
The pills were seized, and the case remains under investigation by Homeland Security Investigations.
“I can tell you that the dangers of fentanyl cannot be overstated,” said Director of Field Operations Marty C. Raybon. “Given that just 2 milligrams can be a lethal dose, this amount had the potential to kill over 1.3 million people.”
The discovery is the largest of its kind for the Port of Detroit and one of the largest inbound fentanyl seizures on the northern border within the last five years.
