Food irradiation is one of the most extensively and thoroughly studied
methods of food preservation. Despite voluminous data on safety and w
holesomeness of irradiated foods, food irradiation is still a ''proces
s in waiting.'' Although some countries are allowing the use of irradi
ation technology on certain foods, its full potential is not recognize
d. Only 37 countries worldwide permit the use of this technology. If u
sed to its full potential, food irradiation can save millions of human
lives being lost annually due to food-borne diseases or starvation an
d can add billions of dollars to the world economy. This paper briefly
reviews the history and chemistry of food irradiation along with its
main applications, impediments to its adoption, and its role in improv
ing food availability and health situation, particularly in developing
countries of the world.
