UV germicidal chambers - best practices

The UMN Swine Disease Eradication Center (SDEC), along with Center for Animal Health and Food Safety, developed a short video and a set of hand-outs to show producers the do's and don't's of UV boxes. View the video and materials on SDEC's website (

Ultraviolet (UV) germicidal chambers, also known as UV boxes, are used in farm biosecurity programs to decontaminate objects entering farms. In these chambers, UV light is used to inactivate pathogens by destroying or disrupting the pathogen's nucleic acid. This results in a reduction in the number of viable organisms on surfaces.

Research has found that the effectiveness of the UVC light depends mostly on the length of time of UVC exposure and UVC light intensity.
