A cabbage field is seen near the area where “Roberto” and other Mexican laborers picked cabbage for Borzynski Farms in the fall of 2016. The Wisconsin Department of Workforce Development received a tip that the workers were being held “prisoner.” DWD investigated and cited the head of a farm labor contracting firm for preventing the men from speaking to outsiders. It is not clear who contacted federal authorities. Borzynski Farms said in a statement it had no knowledge about the alleged trafficking.
