Interpretive Summary:

Technical Abstract: Ultraviolet C (UV-C) employs physical light energy to inactivate microorganisms. This article discusses factors affecting the efficacy of UV-C against common foodborne pathogenic bacteria for food surface decontamination, means to assess and overcome the shading effect, survival and growth of pathogens during post-UV-C storage, formation of viable but nonculturable bacteria due to UV-C treatments, combinations of UV-C with other interventions to achieve synergistic effects, and in-package UV-C treatment. Some research on pulsed light is also included as the germicidal effect of pulsed light is mainly due to the UV-C component of the light spectrum. Further research needs, inactivation mechanisms, and challenges for commercial application are also addressed.
