“CBP officers intercepted this load of fentanyl, the largest thus far in port history, thanks to great teamwork and the utilization of all available tools and resources,” said Port Director Carlos Rodriguez, Hidalgo/Pharr/Anzalduas Port of Entry. “It is important to remember how lethal fentanyl is, which is why our officers always work wearing personal protective equipment and use vital equipment which can identify these dangerous substances before officers handle them.”
