Interpretive Summary: This study sought to evaluate a novel two-sided drop-through photonic decontamination system developed by PulseForge Inc. that employs pulsed light technology on whole wings and tenders and its efficacy on reducing Salmonella, Enterobacteriaceae, and aerobic bacteria counts. Four repetitions for a total of N=320 samples were evaluated with 8 treatments. Treatments included a control (no treatment), pulsed light treatment (PL), 30s water dip, 30s water dip with PL, 30s peracetic acid dip (PAA, 200 ppm), 30s PAA dip with PL, 3 parts simultaneously with PL, and 5 parts simultaneously with PL. 5 wings and 5 tenders were evaluated per treatment per repetition. Parts were inoculated with 0.1 mL of 10^6 Salmonella and 1 h was allowed for attachment. Then, each treatment was performed and treatments that included PL were dropped through the machinery and collected in a sterile bag. Samples were evaluated for Salmonella, Enterobacteriaceae (EB), and aerobic bacteria (APC). Bacterial counts were log transformed and are reported as log10 CFU/mL. Data were analyzed using the general linear models procedure and means were separated by Tukey’s HSD with significance at P=0.05. Treatment was significant for both wings and tenders (P<0.0001). PL reduced Salmonella, EB, and APC by 0.71, 0.66, and 0.62, respectively, on wings, and 0.36, 0.32, and 0.25, respectively, on tenders compared to the control. When water with PL was compared to water alone, Salmonella, EB, and APC decreased by 0.64, 0.64, and 0.74 on wings. Only APC was reduced, by 0.29, on tenders when water with PL was compared to water alone. When PAA with PL was compared to PAA, Salmonella, EB, and APC decreased by 0.55, 0.30, and 0.35 on wings and 0.75, 0.40, and 0.44 on tenders. Finally, when 3 parts were simultaneously treated with PL, Salmonella, EB, and APC were reduced by 0.65, 0.63, and 0.57 on wings, and 0.54, 0.55, and 0.40 on tenders compared to untreated control. Similarly, when 5 parts were treated with PL, Salmonella, EB, and APC were reduced by 0.62, 0.64, and 0.64 on wings, and 0.53, 0.53, and 0.43 on tenders. These results demonstrate that the use of PL consistently reduced the levels of Salmonella, EB, and APC on single and multiple parts in comparison to parts not treated with PL.
