Interpretive Summary:

Technical Abstract: A research priority for the produce industry is the development of an effective, safe and commercially applicable kill step. Irradiation is a nonthermal process that has been shown to inactivate human pathogens from fruits and vegetables. Irradiation treatment at 1.0 kGy can reduce the surface populations of E. coli O157:H7 on leafy vegetables by 4 logs (99.99%), without significantly impacting the product’s visual appeal and texture. Recent reports demonstrate that irradiation is also effective in reducing populations of biofilm-associated and leaf-internalized bacteria, i.e. within environments that protect against conventional chemical sanitizers. However, higher doses are evidently required when targeting leaf-internalized populations. This presentation will review the latest research data on applications of irradiation to leafy vegetables, tomatoes, cantaloupe and other produce commodities of particular concern, from a food safety and a food quality standpoint.
