(CNN) A truck driver hauling frozen strawberries from Mexico into the United States is in custody after customs officers at a Texas port found nearly $13 million worth of methamphetamine hidden in the trailer.

In a statement, Customs and Border Protection said officers working at the Pharr-Reynosa International Bridge cargo facility Saturday encountered a 42-year-old male Mexican citizen with a commercial shipment of frozen strawberries arriving from Mexico.

CBP referred the shipment for further inspection and discovered 350 packages of alleged methamphetamine concealed within the trailer.

Authorities seized the tractor/trailer along with 906 pounds of methamphetamine (411 kg) that was worth about $12,700,000, CBP said.

"This was an outstanding interception our officers accomplished this weekend," said Port Director David Gonzalez of Hidalgo/Pharr/Anzalduas Port of Entry.
