In this study, we tested 15 naturally occurring isoflavones and their metabolites for their possible antibacterial properties against nine Gram-positive and Gram-negative bacteria. The in vitro antibacterial activity was determined using the broth microdilution method, and the results were expressed as minimum inhibitory concentrations (MICs).

Abstract

BACKGROUND

Aspergillus niger has been reported as a potentially dangerous pathogen of date-palm fruits in Saudi Arabia due to the production of fumonisin B2 (FB2) and ochratoxin A (OTA). In a trial to disinfect this product, a double atmospheric pressure argon cold plasma (DAPACP) jet system was set up and evaluated against spore germination and mycotoxin production of the pathogen.

Spores of toxigenic Clostridium difficile and spores of food-poisoning strains of Clostridium perfringens show a similar prevalence in meats. Spores of both species are heat resistant and can survive cooking of foods. C. perfringens is a major cause of foodborne illness; studies are needed to determine whether C. difficile transmission by a similar route is a cause of infection.

Vibrio vulnificus infection can progress to necrotizing fasciitis and death. To improve the likelihood of patient survival, an early prognosis of patient outcome is clinically important for emergency/trauma department doctors. To identify an accurate and simple predictor for death among V. vulnificus–infected persons, we reviewed clinical data for 34 patients at a hospital in South Korea during 2000–2011; of the patients, 16 (47%) died and 18 (53%) survived.

We report the first detection of tetrodotoxins (TTX) in European bivalve shellfish. We demonstrate that TTX is present within the temperate waters of the United Kingdom, along the English Channel, and can accumulate in filter-feeding molluscs. The toxin is heat-stable and thus it cannot be eliminated during cooking.

Yael Kotton, Michal Gordon, Vered Chalifa-Caspi and Naiel Bisharat In 1996 a common-source outbreak of severe soft tissue and bloodstream infections erupted among Israeli fish farmers and fish consumers due to changes in fish marketing policies. The causative pathogen was a new strain of Vibrio vulnificus, named biotype 3, which displayed a unique biochemical and genotypic profile.

This paper investigates the factors that are affecting food safety in Canada today, and those that will become increasingly important in the future. The tools used to complete this analysis are primarily the review of scientific and “gray” literature, and the analysis of multiple sources of data. We develop a methodology for ranking the factors and rank the factors according to their predicted effect on foodborne disease in Canada.

Winter salad is a kind of pickle made of different vegetables and is consumed specially in Khorasan Province. The spontaneous fermentation process is mainly carried out by lactic acid bacteria (LAB). The aim of this study was to isolate and identify the LAB species involved in winter salad fermentation at different fermentation time intervals to introduce the native strains.

To meet the requirements of high-quality safe productsstarter cultures are used to produce fermented sausages. The effects of 3 commercial starter cultures, namely SM-194, T-SPX, and SM-181, on histamine accumulation and quality parameters including microbial quality, pH, water activity, and total volatile base nitrogen, as well as the color and texture properties, were evaluated during the fermentation and ripening of fermented sausages.

As a 1st stepthis study aimed at investigating the microbial quality of liquid egg white in a French egg processing company. Thirty raw and 33 pasteurized liquid egg white samples were analyzed. Pasteurization was globally found efficient on mesophilic contaminants (1.7 ± 1.6 and 0.8 ± 0.9 log CFU/mL in raw and pasteurized samples, respectively), including for the control of Salmonella. However, Gram-positive enterococci were still detected in the pasteurized samples.

Ginger oleoresin was extracted from ginger rhizomesZingiber officinale) using acetone. The high-performance liquid chromatography analysis revealed gingerol to be the major compound of the oleoresin and accounted to 12.8 ± 0.5%. The oleoresin comprised rich fraction of 52.4 ± 0.6 mg GAE/g and exhibited 77.66 ± 0.8% antioxidant activity.
