Federal agents seized more than $6 million in counterfeit FIFA World Cup merchandise at the seaports of Houston and Galveston, U.S. Customs and Border Protection announced Thursday.

The Houston port, one of the nation's largest shipping hubs where cargo is loaded and unloaded along the Gulf of Mexico, was heavily analyzed by Border Patrol officers due to the city hosting World Cup games, the agency said in a news release.

CBP said checking the cargo is a common practice used for other events, such as the Super Bowl.
