Transportation boxes as vectors of disease transmission

Whether they are used as a means of transportation or as storage, boxes or trays constitute a potential risk in cross contamination in clean environments.

Microorganisms and their biofilm and toxins can built up very quickly on the surfaces, if routine cleaning is inadequate or neglected. Disinfection with certain chemicals can cause selection of dangerous superbugs that can outlive standard cleaning procedures. At worst case, the bacteria can end up on sterile medical devices, where it can cause illnesses and even deaths.

Box and tray disinfection

Through the years, SonoSteam has managed to show that a simple combination of steam with ultrasounds can change the way we think about hygiene practices and disinfection processes. Imagine a process that can replace or minimize the use of dangerous chemicals. Decrease the amount of water rinses and save time and extra costs on cleaning processes. Taking hygiene practices to another level shouldn’t be a complicated and costly affair.

Pilot and industrial scale application and results

SonoSteam disinfection has been evaluated in pilot and industrial scale studies. Pilot scale studies demonstrate the disinfection effect of critical high contaminations, which only may occur occasionally on boxes and trays under real conditions. In such cases, SonoSteam decontamination achieves more than 7 log reductions on Enterobacteriaceae (EB) and Total Viable Count (TVC). Under real conditions, unwashed boxes may be contaminated with blood residues and organic matter. Under normal circumstances a pre-wash or rinse step will wash off visible residues prior to the disinfection. However, if the washing step fails to remove residues, SonoSteam can still perform an effective disinfection of such surface, leaving the surface free from microbial contamination.

Sampling technique

Sampling techniques in pilot and industrial scale applications involved the use of direct plating, swabbing of difficult areas and structures on the surfaces and the use of approved contact plates with low detection limit. Furthermore, ATP analysis was performed as an indication of cleaning effect. It is the combined results from all methods that confirms the performance of the system. In all cases, the success criteria is to reach complete reduction (detection limit under 1 CFU/cm2) or the acceptable limit for semi-critical surfaces in hospital environments (2.5 CFU/cm2).
