Eight containers were pulled from the water by dive teams and salvage crews, the U.S. Coast Guard said Sunday in a post on X.
It's still not clear how many containers remain in the water, but the salvage and clean-up process is still underway after last week's mishap.
About 75 containers came tumbling off the vessel named the Mississippi Tuesday morning, but no injuries were reported, according to Port of Long Beach spokesperson Art Marroquin.
Cargo spill incident at Port of Long Beach shows 'how dangerous this job is' for workers, CEO says
"Although this incident was at one berth at the Port, we will continue to act with caution as we recover containers and restore full operations at the Pier G terminal as quickly and safely as possible," said Port of Long Beach CEO Mario Cordero. "Thanks to the quick response by all involved first the workers and companies right at the docks working the ship, then on to all of the agencies who have responded to protect life, safety and commerce."
Cargo operations were temporarily suspended at the terminal as responders worked to secure the containers.
Some merchandise could be seen floating, but most of the containers that went into the water did not break open. Several landed on a barge that was positioned alongside the Mississippi.
The cargo containers from China were carrying loads of merchandise - such as shoes, clothing and electronics - that were destined for stores across the U.S. such as Costco, Target, Walmart and even small businesses.

An investigation led by the U.S. Coast Guard and the National Transportation Safety Board is underway to determine the cause of the incident.
"Until the investigation happens and we have some answers, we will make sure that all safety protocols are adhered to," said Gary Herrera, president of the International Longshore and Warehouse Union Local 13. "We will not be sending our members up on a ship until it's safe to do so. But on the dock, we are continuing to... move containers from the water on to the dock, out of the bay, for the safety of the channel."
