FAO Rinderpest Campaign Cambodia, Siem Reap province, 1966. Another buffalo is vaccinated against Rinderpest. For the last five years the Food and Agriculture Organization of the United Nations (FAO) has been assisting the Government of Cambodia to conduct a full-scale campaign aimed at the eradication of rinderpest. This involves the vaccination of some two-and-a-half million cattle and buffaloes, many of them in remote jungle and mountain areas. The operation has been a truly international one with FAO coordinating the generous help given by Japan, Australia, France and the United States, while Cambodia has supplied the services of the Pasteur institute at Phnom Penh, research and laboratory workers, and the trained teams of vaccinators. It will be necessary to continue the campaign for at least another three years in order to eliminate the danger to the livestock industry of Cambodia and her neighbouring countries.
