Efficacy of Ultraviolet-C Light to Eliminate Staphylococcus Aureus on Precooked Shredded Bullfrog Back Meat

The aim of this study was to investigate the effect of ultraviolet (UV)‐C treatment on the decrease of the inoculated Staphylococcus aureus population in precooked shredded bullfrog meat. The precooked meat was inoculated with 8 log cfu/g of S. aureus. The packaged bullfrog's back meat was then exposed to low (0.65 mW/s/cm2), medium (1.04 mW/s/cm2) and high (1.68 mW/s/cm2) UV‐C intensities over different time intervals (60, 100 and 140 s). A reduction of 3 log cfu/g was observed in all treatments when compared with the inoculated but nonirradiated treatment (T0). All the UV‐C treatments of bullfrog's back meat used in this study reduced the S. aureus count (P
