FOODS 04/12/19 Efficacy of Commercial Sanitizers Used in Food Processing Facilities for Inactivation of Listeria monocytogenes, E. Coli O157:H7, and Salmonella Biofilms. Bacteria entrapped in biofilms are a source of recurring problems in food processing environments.

FOODS 04/12/19 Efficacy of Commercial Sanitizers Used in Food Processing Facilities for Inactivation of Listeria monocytogenes, E. Coli O157:H7, and Salmonella Biofilms

We recently developed a robust, 7-day biofilm microplate protocol for creating biofilms with strongly adherent strains of Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella serovars that could be used to examine the effectiveness of various commercial sanitizers. Listeria monocytogenes 99-38, E.coli O157:H7 F4546, and Salmonella Montevideo FSIS 051 were determined from prior studies to be good biofilm formers and could be recovered and enumerated from biofilms following treatment with trypsin. Extended biofilms were generated by cycles of growth and washing daily, for 7 days, to remove planktonic cells. We examined five different sanitizers (three used at two different concentrations) for efficacy against the three pathogenic biofilms. ►▼ Show Figures Figure 1.

As a non-fastidious organism, it tolerates a range of stressful conditions. Its resistance to high osmolarity was demonstrated by growth up to 13% NaCl and survival under 40% NaCl (Liu et al., 2005; Shabala et al., 2008). L. monocytogenes can grow at low temperatures (Junttila et al., 2008) and its minimal growth temperature is expected to be at −2°C (Augustin et al., 2005). It withstands acidic and alkaline environments as well as low water activity conditions (Nolan et al., 1992; Koutsoumanis et al., 2003; Shen et al., 2016).

Enhanced L. monocytogenes growth inhibition was observed in multibacterial cultures. Strong and weak competitor L. monocytogenes strains were identified. The significance of interactions for strain persistence warrants further studies. Abstract Interactions and competition between resident bacteria in food processing environments could affect their ability to survive, grow and persist in microhabitats and niches in the food industry.

It is a major concern for the food industry, since microorganism, growing in biofilms is protected against cleaning and disinfection and is difficult to eradicate. Aim of this study was to develop a protocol to assess the ability of two flexible packaging materials, named HGP40 and GND35, submitted to corona discharge treatment, to limit the production of L.m. biofilm at 12±1°C.

This is attributed to its easy survival on contact surfaces, resistance to disinfectants or antibiotics and growth under the stringent condition used for food processing and preservation thereby leading to food contamination products by direct or indirect exposure. Brazilian Journal of Microbiology Available online 9 February 2017 Growth, viability and architecture of biofilms of Listeria monocytogenes formed on abiotic surfaces.

Abstract The pathogenic bacterium Listeria monocytogenes can persist in food processing plants for many years, even when appropriate hygienic measures are in place, with potential for contaminating ready-to-eat products and, its ability to form biofilms on abiotic surfaces certainly contributes for the environmental persistence.

In this research, L. monocytogenes was grown in biofilms up 8 days attached to stainless steel and glass surfaces, contributing for advancing the knowledge on architecture of mature biofilms, since many literature studies carried out on this topic considered only early stages of cell adhesion.

At 15 °C, disruptions in genes dltB, lmo1080, lgt, lmo1068 reduced biofilm formation. Himar1 Tn insertions in flaA, cheR, lmo0543, lmo1224 increased biofilm formation. Several biofilm mutants were resistant to DNase, proteinase K or pectinase treatments. Susceptibility to benzalkonium chloride decreased with biofilm maturity and amount. Abstract.

Abstract A total of 98 previously characterized and serotyped L. monocytogenes strains, comprising 32 of 1/2a; 20 of 1/2b and 46 of 4b serotype, from clinical and food sources were studied for their capability to form a biofilm.

The microtiter plate assay revealed 62 (63.26%) strains as weak, 27 (27.55%) strains as moderate, and 9 (9.18%) strains as strong biofilm formers. Among the strong biofilm formers, 6 strains were of serotype 1/2a and 3 strains were of serotype 1/2b. None of the strain from 4b serotype exhibited strong biofilm formation. No firm correlation (p = 0.015) was noticed between any serotype and respective biofilm formation ability. Citation: Doijad SP, Barbuddhe SB, Garg S, Poharkar KV, Kalorey DR, Kurkure NV, et al.

Biofilms: Impact on the Food Industry. SANITATION | June/July 2012 By Michael Cramer Last month, I went to the dentist for my routine 6-month checkup. Maintaining good oral health has always been important to me and was stressed in our family when I was growing up. As my father used to quip, “Be true to your teeth or your teeth will be false to you.” The dental hygienist cleaning my teeth asked if I brush my teeth manually or if I use an electric toothbrush.

FOOD PRODUCTION 29/09/09 Listeria biofilm under attack from new disinfectant . Sterilix Corporation and an ARS researcher claim to have developed a 100 per cent effective disinfectant for removing biofilms containing Listeria monocytognes from meat processing facilities. L. monocytognes can thrive on the work surfaces of meat processing plants because it can withstand low temperatures and can even grow in or on refrigerated foods.

The hardy pathogen is also a serious public health problem. According to the US Department of Agriculture (USDA), L. monocytognes causes serious illness in 2,500 people a year, resulting in 500 deaths. Collaboration To help companies fight the problem, Sterilex Corporation joined forces with Agriculture Research Service (ARS) microbiologist Judy Arnold.
