Dockworkers at the Port of Mobile joined about 45,000 union strikers from Maine to Texas who walked off the job for the first time since 1977. While any port can handle any type of goods, some ports are specialized to handle goods for a particular industry. The ports affected by the shutdown include Baltimore and Brunswick, Georgia, the top two busiest auto ports; Philadelphia, which gives priority to fruits and vegetables; and New Orleans, which handles coffee, mainly from South America and Southeast Asia, various chemicals from Mexico and North Europe, and wood products such as plywood from Asia and South America.
