Customs and Border Protection (CBP) officers found more than $2.7 million worth of marijuana hidden inside nearly 1,000 boxes of Serrano peppers.
A Freightliner carrying the load of peppers was attempting to cross the Pharr-Reynosa International Bridge on Saturday.
During a secondary inspection, officers found 350 packages of marijuana commingled with the peppers inside the trailer.
Officials said the packages weigh a total of 2,732 pounds.
The drugs and the tractor trailer were confiscated.
