TL;DR: It is demonstrated that the essential oils are potential and promising antifungal agents which could be used as biofungicide in the protection of tomato against B. cinerea, the causal agent of grey mould disease of tomato.

TL;DR: Together, fractional inhibitory concentrations < or = 0.5 and log DP<-1 indicated synergistic action between four natural antimicrobials and as many as three antibiotics to which these bacteria were normally resistant.

TL;DR: A greater understanding of the structure and composition of thermophilic bacilli biofilms within the context of the milk processing environment and their link with spore formation is needed to develop better control measures.

TL;DR: The antimicrobial effect of oregano essential oil at 0.6 or 0.9%, nisin at 500 or 1000 IU/g, and their combination against Salmonella Enteritidis was studied in minced sheep meat during storage at 4 degrees or 10 degrees C for 12 days.

TL;DR: The findings indicated that Salmonella contamination was common in retail meats, and that the Salmoneella isolates were phenotypically and genetically diverse.

TL;DR: It is concluded that many drivers may result in increased food safety risks, requiring active governmental policy setting and anticipation by food industries whereas other drivers may decrease foodSafety risks.

TL;DR: The results suggest that POMx oligomers, composed of gallic acid, ellagic acid and glucose units, may account for the enhanced growth of probiotic bacteria.

TL;DR: Two new computing resources (R packages) specifically developed to help risk assessors in their projects are introduced, illustrated through a risk assessment of hemolytic and uremic syndrome in children linked to the presence of Escherichia coli O157:H7 in ground beef.

TL;DR: In this paper, Lactobacillus plantarum C48 and Lactococcus lactis subsp. lactis PU1, previously selected for the biosynthesis of gamma-aminobutyric acid (GABA), were used for sourdough fermentation of cereal, pseudo-cereal and leguminous flours.

TL;DR: The results show that the hyperspectral imaging is able to rapidly discriminate commercial maize kernels infected with toxigenic fungi from uninfected controls when traditional methods are not yet effective.

TL;DR: This study showed that a high purity GOS, administered in a confection product at doses of 5g or higher, was bifidogenic, while a dose of 2.5g showed no significant effect, however, the results also showed that even when GOS was administered for many weeks and at high doses, there were still some individuals for which a bIfidogenic response did not occur.

TL;DR: Overall, S. Tennessee displayed more biofilm formation in vitro and attached more strongly to lettuce than other serovars and Salmonella spp.

TL;DR: The PCR method can be used as an alternative to bioassay for detection and genotyping of T. gondii, and to quantify the organism in meat samples of various sources.

TL;DR: The antimicrobial activity of newly developed cellulose-silver nanoparticle hybrid materials was investigated during storage of minimally processed "Piel de Sapo" melon, presenting remarkably lower yeast counts, lower degrees Brix values, and a juicier appearance after 10 days of storage.

TL;DR: Data indicate that the coating of the probiotics in chocolate is an excellent solution to protect them from environmental stress conditions and for optimal delivery, and could act as a trigger for new research to identify new balanced matrices.

TL;DR: The Enterococcus genus, a member of the Lactic Acid Bacteria, is found in various environments, but more particularly in the intestines of humans and other animals, and many of these enterocins have been found to be active against Listeria monocytogenes, and a few have also been reported to beactive even against Gram negative bacteria, an unusual property for the bacteriocins produced by LAB.

TL;DR: B. longum PCB 133, possessing interesting probiotic properties and a marked anti-Campylobacteria activity both in vitro and in vivo, is an excellent candidate for being employed as additives to feed for poultry for the reduction of food-borne campylobacteriosis in humans.

TL;DR: The antimicrobial effect of constituents of the American cranberry; sugar plus organic acids, phenolics, and anthocyanins, against Escherichia coli O157:H7 was investigated to determine the minimal inhibitory concentration, minimal bactericidal concentration, and log CFU/ml reductions, at their native pH and neutral pH.

TL;DR: The end products produced from kimchi LAB, like 3,6-bis(2-methylpropyl)-2,5-piperazinedion identified in this study, may be a promising alternative to chemical preservatives as a potential biopreservative which prevent fungal spoilage and mycotoxin formation in food and feed.

TL;DR: Accurate health information, including reliable estimates of the burden of foodborne disease, can improveFoodborne disease prevention, foster global health security, promote economic growth and development and strengthen evidence-based policy making.

TL;DR: The harmful effects on the quality and safety of dairy products caused by aerobic spore-forming isolates obtained from raw milk were characterized and it was demonstrated that some strains are capable of growing at room temperature and staying stable at refrigeration temperatures.

TL;DR: Results obtained indicate that LAMP offers an interesting new assay format for the rapid and specific DNA-based detection and identification of agriculturally important toxigenic fungi in pure cultures and in contaminated sample materials and therefore presents an alternative to PCR-based assays.

TL;DR: P. betle EO exhibited special merits possessing antifungal, aflatoxin suppressive and antioxidant characters which are desirable for an ideal preservative and its application as a plant based food additive in protection and enhancement of shelf life of edible commodities during storage and processing is strongly recommended in view of the toxicological implications by synthetic preservatives.

TL;DR: 3D models of human and animal gut represent a promising in vitro system to mimic in vivo situation without the use of transformed cell lines.

TL;DR: This study is the first to identify the yeast communities associated with grapes in China using molecular methods and the results enrich the knowledge of wine-related microorganisms, and can be used to promote the development of the local wine industry.

TL;DR: Although encapsulation is often mentioned as a quick-fix for preserving probiotic viability in dry and semi-dry products, more studies are needed which validate the broader potential of this approach at different shelf-life expectancies, water activities, and product matrices.
