PORT-AU-PRINCE, Haiti—It was lunchtime in one of Haiti’s worst slums, and Charlene Dumas was eating mud.

With food prices rising, Haiti’s poorest can’t afford even a daily plate of rice, and some take desperate measures to fill their bellies.

Charlene, 16 with a one-month-old son, has come to rely on a traditional Haitian remedy for hunger pangs: cookies made of dried yellow dirt from the country’s central plateau.

The mud has long been prized by pregnant women and children here as an antacid and source of calcium. But in places like Cite Soleil, the oceanside slum where Charlene shares a two-room house with her baby, five siblings and two unemployed parents, cookies made of dirt, salt and vegetable shortening have become a regular meal.

The Food and Agriculture Organization of the United Nations is increasingly concerned about food prices, which are up as much as 40 percent on some Caribbean islands. Floods and crop damage from the 2007 hurricane season forced the agency to declare states of emergency in Haiti and several other countries.

Caribbean leaders held an emergency summit in December to discuss cutting food taxes and creating large regional farms to reduce dependence on imports.

At the market in the La Salines slum, two cups of rice now sell for $0.60, up 10 cents from December and 50 percent from a year ago. Beans, condensed milk and fruit have gone up at a similar rate, and even the price of the edible clay has risen over the past year by almost $1.50. Dirt to make 100 cookies now costs $5, the cookie makers say.
