A truckload of methamphetamine disguised as a shipment of watermelons was seized at a U.S.-Mexico border crossing in San Diego, U.S. Customs and Border Protection said.

The methamphetamine, valued at more than $5 million, was found Aug. 16 when the cargo aboard a tractor-trailer from Mexico was unloaded for a detailed inspection, the agency said in a statement.

Among real watermelons, officers found 1,220 packages wrapped in paper colored to look like watermelon skins.
