Over 100 million people a year could be fed by the grains that are lost as a result of infestation and consequent spoilage. Highly significant, then, is the development of fumigants designed to combat this waste. With aluminum phosphide now approved by FDA as a food additive, this fumigant is certain to gain wide use. It involves no residues, and because it involves no pressure in storage and is not a liquid, it offers considerable advantage toward safety in handling and storage.
