Disinfection of meat transportation – naturally contaminated with Enterobacteriaceae and meat residues
Challenges with meat transportation boxes occur because of severe contamination of meat, blood and oily residues. These surfaces may contribute to additional problems with residue accumulation on dried surfaces and therefore the risk of heavy bcontamination. In turn, high contamination increases the risk of cross-contamination directly to meat products and even packaging.
SonoSteam processes kill the microorganisms on any challenging surface
SonoSteam has been tested on naturally contaminated meat transportation boxes that were heavily contaminated with meat and blood. These boxes were treated with SonoSteam for only one sec. at 90°C in continuos treatment. Swabbing was performed before and after the treatment and samples were analyzed for Enterobacteriaceae. The contamination levels before the treatment were around log 5. Following SonoSteam treatment, full reductions were accomplished. During swabbing, it was noticed that meat residues were far more easily detached from the surface in comparison to untreated areas. Thus, the SonoSteam process was able to coagulate meat proteins of the surface, but without burning them onto the surface.
