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 says officers discovered more than 7,500 pounds (3,401 kilograms) of marijuana in the peppers' pallets.
Acting CBP Commissioner Mark Morgan congratulated the officers on Twitter and noted it was the second large seizure of marijuana there within days.
Authorities seized more than 10,600 lbs (4,808 kilograms) of marijuana in a shipment of plastic auto parts at the port Tuesday.
