Poultry workers say they are routinely denied bathroom breaks, according to a report by Oxfam America, based on interviews with workers at some of the nation's biggest poultry companies, including Tyson Foods, Perdue and Pilgrim's over the last three years.

A new survey of more than 500 poultry workers in Arkansas found that 62 percent had experienced some kind of wage violation (e.g. not being paid or being deducted unfairly for safety gear) and 44 percent reported being verbally or sexually harassed.

In a 40-page report, Oxfam America suggests several steps to improve Feed the Future, an Obama administration initiative that uses public-private partnerships to boost local food production in targeted countries.

The largest U.S. hunger-relief charity, Feeding America, says two out of five client households "have at least one member that has worked full-time but still utilize charitable food programs to make ends meet."

The world's largest cereal maker, Kellogg Co, said it will reduce energy and greenhouse gas emissions by 15 percent by 2020 to combat climate change.
