The biochemistry and microbial ecology of 2 similar types of waterymul) kimchi, containing sliced and unsliced radish and vegetables (nabak and dongchimi, respectively), were investigated. Samples from kimchi were fermented at 4, 10, and 20 °C were analyzed by plating on differential and selective media, high-performance liquid chromatography, and high-throughput DNA sequencing of 16S rDNA.

The count of Listeria monocytogenes was determinedbefore and after heat treatment, in 200 samples of dumplings of 9 brands and with different types of stuffing. Analyses were conducted according to ISO 11290–1 standard and with real-time PCR method. The highest count of L.

Escherichia coli is one of the foodborne pathogens associated with several cases of human sickness. Duck meat is an excellent source of animal-derived high quality proteins. This study was undertaken to investigate the possible transmission of diarrheagenic E. coli from consumption of duck meat and giblets. Additionally, expression of some virulence-associated genes in the isolated E. coli serotypes was examined using polymerase chain reaction.

Biofilm of Cronobacter sakazakii on food contact surfaces is the important source of persistent contamination in powdered infant formula. This study aimed to assess the effects of Ca2+ and Mg2+ on biofilm formation. Results indicated that the biofilm-forming ability was strain specific and divalent cation concentrations dependent. Most of C. sakazakii formed the highest amount of biomass at 1.50% MgCl2 (17 strains, 74%) and 0.25% CaCl2 (10 strains, 43.4%).

Due to climate change, sea ice experiences changes in terms of extent and physical properties. In order to understand how sea ice microbial communities are affected by changes in physiochemical properties of the ice, we used 454-sequencing of 16S and 18S rRNA genes to examine environmental control of microbial diversity and composition in Antarctic sea ice.

Shiga toxin-producing Escherichia coli (STEC) produce shiga toxins (Stxs) that can cause human disease and death. The contamination of food products with STEC represents a food safety problem that necessitates rapid and effective detection strategies to mitigate risk.

The aim of our study was to determine the efficacy of three different adsorbents, inorganic (modified zeolite), organic (esterified glucomannans) and mixed (inorganic and organic components, with the addition of enzymes), in protecting broilers from the toxic effects of ochratoxin A in feed. Broilers were fed diets containing 2 mg/kg of ochratoxin A (OTA) and supplemented with adsorbents at the recommended concentration of 2 g/kg for 21 days.

In order to elucidate the main predictors of Vibrio cholerae dynamics and to estimate the risk of V.cholerae related diseases, a recently developed direct detection approach based on FISH and solid phase cytometry (CARD-FISH/SPC) was applied in comparison to cultivation for water samples from the lake Neusiedler See, Austria and three shallow alkaline lakes over a period of 20 months. V.cholerae attached to crustacean zooplankton was quantified via FISH and epifluorescence microscopy.

In the past decade, the most prevalent norovirus genotype causing viral gastroenteritis outbreaks worldwide, including China, has been GII.4. In winter 2014–15, norovirus outbreaks in Guangdong, China, increased. Sequence analysis indicated that 82% of the outbreaks were caused by a norovirus GII.17 variant.

To the Editor: In Nigeria, from February 2006 through July 2008, outbreaks of highly pathogenic avian influenza (HPAI) subtype H5N1 virus infection in poultry negatively affected animal and public health as well as the agricultural sector and trade. These outbreaks were caused by viruses belonging to genetic clades 2.2 and 2.2.1 (1).

Kim, Dong-Hyeon et al. Lactobacillus kefiranofaciens is an indicator microorganism for kefir and a key factor in kefir grain formation and kefiran production. We designed a novel real-time PCR primer and probe set, LKF_KU504, for the rapid detection of L. kefiranofaciens. In inclusivity and exclusivity tests, only 14 L. kefiranofaciens strains were positive among 61 microorganisms, indicating 100% sensitivity and specificity.

Ward, Michelle et al. Contaminated produce causes approximately 1 million cases of foodborne illness and 1 billion dollars in damages to the U.S. economy annually. The environmental conditions, especially weather, that influence the inoculation, proliferation, and dispersal of microbial load on produce are not well understood.
