One of the biggest U.S. meatpackers is creating an internal company to clean some of its processing plants, after a private sanitation firm JBS USA employed, was accused of hiring children for dangerous work.

The launch shows the complexities involved in replacing Packers Sanitation Services, a firm that contracts to clean slaughterhouses. 

In February, the U.S. government says Packers Sanitation Services paid 1.5 million dollars US in penalties for employing more than 100 underage teenagers at meat plants across eight states.

The new company, JBS Sanitation, will “immediately begin the transition” to cleaning 10 JBS USA facilities, which produce beef and pork.

JBS Sanitation will also do in-house cleaning for Pilgrim’s Pride Corp. and create hundreds of union jobs.

JBS USA is the North American unit of Brazil’s JBS SA, which also owns most of Pilgrim’s Pride.
