Could a Peanut Paste Called Plumpy'nut End Malnutrition? - NYTimes.com: "Elsewhere, local producers are simply ignoring the patent. In Haiti, two manufacturers are making products similar to Plumpy’nut independently of Nutriset: one is Partners in Health, the charity co-founded by the prominent global-health activist Paul Farmer. Partners in Health harvests peanuts from a 30-acre farm or buys them from a cooperative of 200 smallholders. It’s planning to build a larger factory, but for now the nuts are taken to the main hospital in Cange, where women sort them in straw baskets, roast them over an outside gas burner, run them through a hand grinder and mix all the ingredients into a paste that is poured into reusable plastic canisters. Peanuts in Haiti and throughout the developing world have a high incidence of aflatoxin, a fungus that can sicken children, especially fragile ones. But Partners in Health says the product, which it calls Nourimanba, is safe."
