. Refrigerated frankfurters were then placed on a sterile surface,
rolled in 1 mL of diluted inoculum, including the ends, to a
final concentration of 105 CFU/g, and placed in a refrigerator for
approximately 30 min prior to UV and FP treatments. The inoculation,
105 CFU/g, is relatively high in comparison to the relatively
low numbers associated with naturally occurring contaminations
of frankfurters (Gombas and others 2003)
