A mystery substance found in a truck that authorities believe was hauling narcotics has sickened numerous law enforcement officers in Louisiana, and at least 18 have been quarantined as a precaution.

Roberto Bryan Jr., a spokesman for the Drug Enforcement Administration, says 18 DEA agents, Louisiana State Police troopers and Jefferson Parish Sheriff's deputies have been quarantined at East Jefferson General Hospital until the substance is identified.

State police Lt. Doug Cain says several officers were overcome with nausea and dizziness as they searched a suspicious 18-wheeler that had been taken to police headquarters. Officers found several bricks of white powder among the truck's cargo of limes.
