JBS USA and Perdue Farms will each pay $4 million for employing children through third-party staffing agencies, officials announced this week.

The U.S. Department of Labor has entered into an agreement with Perdue Farms Inc. to address child labor violations at its Accomac, Virginia plant.

The problem of kids working in dangerous slaughterhouses continues to be a concern as the Labor Department announced its third agreement this week with a company in the industry agreeing to pay a penalty and reform its practices to help ensure it won’t hire underage workers again.

Agribusiness giants Purdue Farms and JBS Foods, along with a slaughterhouse cleaning company, paid about $8.4 millions in fines for having underaged workers in dangerous jobs.

JSB and Perdue Farms agreed to settlements of $4 million each, while QSA, which employed 54 children, will pay $400,000.
