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.

Perdue Farms and a staffing agency will pay more than $4 million to settle claims that they employed children in hazardous jobs at a chicken processing facility in Virginia, the U.S. Department of Labor said on Wednesday.
