ONCE BioShift chamber stands up to real-world bio-security challenges

PLYMOUTH, MN (June 6, 2018) – ONCE®, the world’s only supplier of research-based agricultural lighting systems, has confirmed their BioShift® Pass-Through Germicidal UV Chamber can efficiently decrease the possibility of a porcine epidemic diarrhea (PED) viral outbreak.

While previous research demonstrated the efficacy of the BioShift® to disable PED and Porcine reproductive and respiratory syndrome (PRRS) virus in laboratory settings, the latest trials were focused on real-world scenarios.  With the cooperation of a major swine producer in southwestern Minnesota, day-old pigs were exposed to items that had been contaminated with a field isolate of the PED virus. One group was subjected to items directly (control), while the second group was subjected to items after UV-C treatment in the BioShift® chamber. After five days, the pigs were assessed for development of disease by tissue pathology at the University of Minnesota. Although 100% of the control group developed an active PED infection, none of the pigs exposed with BioShift® chamber-treated items developed a detectable infection.

“Our previous work gave us confidence in the efficacy of the BioShift® chamber, but we felt it was necessary to close the loop on the research using a farm-based bioassay,” stated Dr. Aaron Stephan, Director of Biological Research & Development at ONCE®. “We wanted to ensure that the use of the BioShift® chamber meaningfully improves biosecurity within a facility. Our research clearly demonstrates the efficacy of the BioShift® chamber for reducing the import of potentially lethal pathogens into a swine facility,” added Dr. Stephan.
