There's a human cost to factory-processed chicken. In the 1960s, the US began a love affair with chicken, and poultry workers paid the cost. Over the past few decades, poultry processing line speeds have increased to meet demand. But that’s happened in tandem with the decline of unions and deregulation of the industry. The result is a high rate of workplace injuries and repetitive motion disorders, with gaps in workplace safety oversight. For this video, we contacted Tyson Foods Inc. and the National Chicken Council for comment.
