Officials say they seized $2.3 million worth of marijuana mixed in with a shipment of jalapeño peppers at a Southern California port. A Customs and Border Protection K-9 unit alerted officers to a shipment of peppers Thursday at the Otay Mesa cargo facility in San Diego.

A CBP news release said officers discovered more than 7,500 pounds — nearly 4 tons — of marijuana in the peppers' pallets.

The release mentioned CBP found a "37-year-old male Mexican citizen entered the port of entry driving a tractor pulling a trailer with cargo manifested as jalapeño peppers."

Authorities seized more than 10,600 lbs of marijuana in a shipment of plastic auto parts at the port Tuesday.

In July, a cargo ship that was seized with nearly 20 tons of cocaine on board — with an estimated street value of $1.3 billion — belonged to JP Morgan Chase. U.S. Customs and Border Protection said it was the largest vessel ever seized in the agency's 230-year history.
