The arrests targeted chicken processing plants operated by Koch Foods, one of the largest poultry producers in the U.S. Last year, Koch Foods paid out $3.75 million to settle an Equal Employment Opportunities Commission class-action suit charging the company with sexual harassment, national origin and race discrimination, and retaliation against Latino workers at one of its Mississippi plants. Labor activists say it’s the latest raid to target factories where immigrant workers have organized unions, fought back against discrimination or challenged unsafe and unsanitary conditions.
