Risk factor-based clustering of Listeria monocytogenes in food processing environments using principal component analysis.

Listeria monocytogenes has a range of strategies that allow it to persist as biofilms in food processing environments (FPE), making it a pathogen of concern to the food industry. The properties of these biofilms are highly variable among strains, and this significantly affects the risk of food contamination. The present study therefore aims to conduct a proof-of-concept study to cluster strains of L.

Architectural Features and Resistance to Food-Grade Disinfectants in - spp. Dual-Species Biofilms.

is considered a foodborne pathogen of serious concern capable of forming multispecies biofilms with other bacterial species, such as spp., adhered onto stainless steel (SS) surfaces. In an attempt to link the biofilms' morphology and resistance to biocides, dual-species biofilms of , in co-culture with either , , or , were assayed to ascertain their morphological characteristics and resistance toward benzalkonium chloride (BAC) and neutral electrolyzed water (NEW).

Methodological Approaches for Monitoring Five Major Food Safety Hazards Affecting Food Production in the Galicia-Northern Portugal Euroregion.

The agri-food industry has historically determined the socioeconomic characteristics of Galicia and Northern Portugal, and it was recently identified as an area for collaboration in the Euroregion. In particular, there is a need for action to help to ensure the provision of safe and healthy foods by taking advantage of key enabling technologies. The goals of the FOODSENS project are aligned with this major objective, specifically with the development of biosensors able to monitor hazards relevant to the safety of food produced in the Euroregion.

Tracking bacteriome variation over time in Listeria monocytogenes-positive foci in food industry.

The variation in microbial composition over time was assessed in biofilms formed in situ on selected non-food and food contact surfaces of meat and fish industries, previously identified as Listeria monocytogenes-positive foci. First, all samples were analysed for the detection and quantification of L. monocytogenes using ISO 11290-1 and ISO 11290-2 norms, respectively.

[Treatment of uretero-renal stones with shock wave lithotripsy. Results and complications with the dornier gemini emse 220f-XXP.].

Objectives: Extracorporeal shock wave lithotripsy is a minimally invasive therapeutic option for the treatment of renal-ureteral lithiasis. The aim of this study was to analyze the results and complications of shock wave extracorporeal lithotripsy treatment with the Dornier Gemini® Generator EMSE 220f-XXP device in patients with renal and ureteral lithiasis.

Material And Methods: Retrospective study including 377 patients with renal or ureteral lithiasis with indication for treatment with extracorporeal shock wave lithotripsy.

Current Knowledge on Biofilms in Food-Related Environments: Incidence, Resistance to Biocides, Ecology and Biocontrol.

Although many efforts have been made to control in the food industry, growing pervasiveness amongst the population over the last decades has made this bacterium considered to be one of the most hazardous foodborne pathogens. Its outstanding biocide tolerance capacity and ability to promiscuously associate with other bacterial species forming multispecies communities have permitted this microorganism to survive and persist within the industrial environment. This review is designed to give the reader an overall picture of the current state-of-the-art in sessile communities in terms of food safety and legislation, ecological aspects and biocontrol strategies.

Antimicrobial activity of essential oils against Staphylococcus aureus biofilms.

The present study was aimed to evaluate the potential of essential oils to remove the foodborne pathogen Staphylococcus aureus from food-processing facilities. The effectiveness of 19 essential oils against planktonic cells of S. aureus was firstly assessed by minimal inhibitory concentration.

Incidence and characterization of Staphylococcus aureus in fishery products marketed in Galicia (Northwest Spain).

A total of 298 fishery products purchased from retail outlets in Galicia (NW Spain) between January 2008 and May 2009 were analyzed for the presence of Staphylococcus aureus. S. aureus was detected in a significant proportion of products (~25%).

Possible role for cryostabilizers in preventing protein and lipid alterations in frozen-stored minced muscle of Atlantic mackerel.

Adding DE 18 maltodextrin (80 g kg(-1)) to high-fat minced mackerel was highly effective against lipid oxidation and protein and color changes during frozen storage. It increased the temperature of ice-melting onset (Tm') and decreased freeze concentration of solutes in the unfrozen water (UFW) phase, which would have allowed it to effectively slow such perturbations. This maltodextrin showed a higher effectiveness against lipid oxidation, but was slightly less effective in preventing the loss of protein solubility than common cryoprotectants, that is, an equiproportional mixture of sucrose and sorbitol.
