Test details
Target microorganism
Enterobacteriaceae and Total Viable Count (TVC)
Application
Slaughter knives
Treatment time
1.0 second
Initial level
Enterobacteriaceae 4.88 log₁₀ CFU/4 cm²; TVC 6.40 log₁₀ CFU/4 cm² (equal to 2,511,886 bacteria per 4 cm² handle)
Reduction achieved
No detectable Enterobacteriaceae or TVC after treatment
Relative reduction
Below the detection limit
Test setting
Knives received from a Danish slaughterhouse, naturally contaminated with meat residues from the process line
Sampling method
Swab sampling before and after treatment; each knife treated individually.
Number of samples
N=3
Detection limit
Below 10 CFU/swab
Limitations and observations
The knives quickly returned toward normal temperature and protein residues did not become fixed to the tested knives.
