The Food and Agriculture Organisation of the United Nations has invited its forty-seven member Governments to send experts to meet in London during August 5–12, for a conference on the problems of infestation of stored foodstuffs. This term includes food undergoing transit, storage and processing. Problems to be studied include measures to prevent infestation such as adequate improved warehousing facilities, as well as a study of methods of pest control used in the various countries. Also to be investigated are world foci of infestation and the channels through which insects, mites, rodents and mould fungi are carried in foodstuffs to all parts of the world. Aspects of the production, availability, and consumption of insecticides, fungicides, fumigants and rodent poisons will also be examined. An attempt will be made to obtain some idea of the extent of the very grave losses which are known to occur through infestation, and to recommend measures which could be applied to prevent these losses. A report of the recommendations of the meetings will be submitted by the Food and Agriculture Organisation to all member Governments and to other interested international agencies.
