LOUISVILLE, Ky. (WDRB) -- The government has seized close to 4,000 pounds of marijuana shipped to the U.S. disguised as lettuce. 

U.S. Customs and Border Protection officers in Laredo, Texas seized more than 5,700 packages, containing nearly two tons of marijuana. 

The pot was packaged in phony bundles fashioned to look like heads of lettuce inside a truck traveling across the Laredo-Colombia international bridge.

Agents tweeted out a picture of the pot-lettuce after the bust. 

The truck hauling the "produce" crossed the Laredo-Colombia Solidarity International Bridge along the Texas-Mexico border. The fake veggie packages were discovered by a narcotics K-9 team, imaging and physical inspection of the trailer.

"This is truly an example of our CBP officers' hard work, experience and dedication to the CBP mission," Port Director Gregory Alvarez said in a statement. "I congratulate the officers in advancing the CBP mission and protecting the public from illegal narcotics."

The drugs have an estimated street value of $741,186, according to the statement. The case is now under investigation with the US Immigration and Customs Enforcement Homeland Security Investigations special agents.

Police say the marijuana has an estimated street value of more than $700,000.
