CNN  —  MANA Nutrition makes a special kind of peanut butter paste that many humanitarian aid workers are familiar with. It is fortified with milk and essential vitamins, packed with calories and sent to severely malnourished children around the world, including some countries in Africa. On Wednesday afternoon, Mark Moore, the CEO and co-founder of the Fitzgerald, Georgia-based plant, got word from the US Agency for International Development: MANA’s contracts with the agency were being canceled.
