Current Issues in Phytosanitary Irradiation

Several issues present barriers to the wider use of phytosanitary irradiation. Because irradiation is characterized as a food additive rather than a process, its use must be disclosed on a label. The labeling requirement may be a drawback for retailers who believe consumers are reluctant to buy irradiated food. The 1-kGy limit is archaic and reduces the efficiency of applying the treatment. The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) has placed limits on the use of modified atmosphere packaging with irradiation, which disrupts commercial practices that ensure superior commodity quality. The limited number of countries that have approved phytosanitary uses of irradiation is hampering broader adoption because of closed markets.
