UV Light Effective Against Bacteria That Causes Foodborne Illnesses

Inactivation of Escherichia coli O157:H7 and Listeria monocytogenes in biofilms by pulsed ultraviolet light

Published: BMC Research Notes, June 2015


The presence of bacteria, including E. coli and Listeria, on ready-to-eat fresh fruits and vegetables pose a threat to consumers. Other methods of decontamination, such as heat or chemicals, cause challenges for food production facilities as they may adversely affect the quality of products or health of customers.


Researchers found that pulsed UV is an “effective nonthermal intervention method for surface decontamination of E. coli O157:H7 and L. monocytogenes on fresh produce and packaging materials.”
