Following circulation of 60% isopropanol at ambient temperature for 1 h, low levels of microbial contamination were detected on the processing equipment after plating on TSAYE. A number of
colonies on TSAYE were tested using the Vitek microbial identification system, but none were found to be Salmonella. In addition, after isopropanol treatment there were no presumptive Salmonella
detected in environmental swabs when plated onto XLD (detection level 0.16 log CFU/cm 2 )
