Migrant workers in Indiana: They harvest our food, but risk labor trafficking

The migrant workers, still soaked with sweat, lumber off an old school bus an hour before midnight and slowly file toward a cluster of mobile homes set back from the highway that cuts through this Knox County farm town. It is the peak of harvest season, and days filled with picking cantaloupe and watermelon for 12 hours or more in the August heat are routine.A young man, his feet bare, limps past me carrying a pair of tattered shoes. He grimaces in pain and fatigue.Each year, thousands of migrant workers follow the harvest from Florida, Georgia and other parts of the South to Northern states such as Indiana, Ohio and Michigan. They pick and pack asparagus, melons, tomatoes and other fruits and vegetables that grace Americans' dinner tables. They settle, sometimes for months, into roadside motels, apartment buildings and mobile home parks in farm towns across the country.Yet they are largely unseen and often isolated from the communities where they live and work. They're vulnerable to exploitation, including wage theft and labor trafficking. And their health and safety are at times put at risk for the sake of the harvest.
