Researchers undertook studies to determine the effectiveness of 13 disinfectants in killing E. sakazakii in suspension, dried on the surface of stainless steel and embedded in biofilms on stainless steel.
Quaternary ammonium-, phenolic-, peroxyacetic acid- and alcohol-based disinfectants used in infant formula preparation settings were evaluated.
The scientists determined the effects of time that elapsed after drying cells on stainless steel, as well as the age of biofilms on the resistance of cells to disinfectants. Their findings show that disinfectants routinely used in hospital, daycare and food service settings are ineffective in killing some cells of E.sakazakii embedded in organic matrices.
