California-based canned tuna company Bumble Bee Foods will have to pay a record $6 million after the death of one of its employees, who was accidentally cooked in an industrial oven in 2012.

The penalty, part of a settlement announced Wednesday, is the largest ever for a workplace safety violation in California involving a single worker.

Jose Melena, 62, entered a 10.6-meter (35-foot) cylindrical pressurized steam cooker as part of his regular job duties on October 11, 2012, before coworkers, who did not realize Melena was inside, loaded the oven and turned it on, trapping and killing him.

Half of the $6-million penalty will go to replacing the outdated tuna ovens so that workers will never again need to enter them, for maintenance or any other reason, according a statement from the office of Los Angeles County District Attorney Jackie Lacey.

The family of Melena, who worked and died at the tuna giant's Santa Fe Springs, California, plant, will receive $1.5 million in restitution.

Bumble Bee will also have to make a public statement conceding guilt as part of the settlement.

The plant's director and former safety manager will also need to issue a statement conceding guilt in addition to paying fines and performing community service.
