Most of Haiti's 8 million people are jobless or without regular work and live on less than US$1 day.
The WFP is helping needy families by providing one-month rations of 50kg of rice, 10kg of pulses and five liters of vegetable oil.
Oxfam is helping coordinate relief and is starting a flood recovery project with US$350,000 from the EU, said William Gustave, an organization official. Caritas, through the Cap-Haitien Catholic Diocese, is providing food to help.
But aid officials said food borrowed from school programs will have to be paid back.
"People need to know that Haiti is at a crisis point and the lack of international assistance is making it worse," Gauvreau said.
"We need help urgently," he said.
