Disinfection with neutral electrolyzed oxidizing water to reduce microbial and to prevent biofilm regrowth in the processing of fresh-cut vegetables
Microbe(s): Total Microbial Count


ABSTRACT
Product decontamination is one of the most important processes of the hygienic practice in food industries such as Minimally Processed Vegetables (MPV) plants and sodium hypochlorite (NaOCl) solutions are commonly used as a biocide for disinfection. Although it may be corrosive and irritating when compared to , reducing the free chlorine concentration needed to sanitize salads, also decreasing water consumption whilst taking into account environmental and food quality impacts.

Inactivation of Listeria monocytogenes/Flavobacterium spp. biofilms using chlorine: impact of substrate, pH, time and concentration
Microbe(s): Listeria monocytogenes, Flavobacterium spp.


ABSTRACT
Aims: To determine the effect of chlorine on mixed bacterial biofilms on stainless steel (SS) and conveyor belt surfaces. Methods and Results: Biofilms were exposed to pH-adjusted (6.5) and non-pH-adjusted solutions of chlorine (200, 400 and 600 ppm) for either 2, 10 or 20 min and survivors enumerated. There were significant differences in cell death relating to chlorine concentration and exposure time for the cells attached to the SS, with solutions adjusted to pH 6.5 being more effective at re...

Inactivation of Listeria monocytogenes biofilms by electrolyzed oxidizing water
Microbe(s): Listeria monocytogenes


ABSTRACT
This study investigates the resistance of Listeria monocytogenes biofilms on stainless steel surfaces to electrolyzed oxidizing (EO) water. A direct agar overlay method was used to estimate the attached bacteria on stainless steel coupons after an EO water treatment. A scraping method was also used to quantify the adherent cell populations after the EO water treatment. The stainless steel surface allowed 10 to 15% of the surface area to be covered by Listeria biofilm when the inoculated stainles...
