Test details
- Target microorganism
- Enterobacteriaceae and Total Viable Count (TVC)
- Application
- Hospital mattress covers
- Treatment time
- 2.0 seconds
- Initial level
- Enterobacteriaceae 2.94 log₁₀ CFU/24 cm²; TVC 4.27 log₁₀ CFU/24 cm² (equal to 18,620 bacteria per 24 cm²)
- Reduction achieved
- No detectable Enterobacteriaceae or TVC after treatment
- Relative reduction
- Below the detection limit
- Test setting
- Mattress covers artificially contaminated with different types of bacteria, treated while fitted to the mattress
- Sampling method
- Swab sampling before and after treatment; each piece treated individually.
- Number of samples
- N=3
- Detection limit
- Below 10 CFU/swab
- Limitations and observations
- No visible, physical or structural changes were observed and no condensed water penetration through the tested mattress cover was found. The cover quickly returned toward normal temperature.
