Khalid, Mohd Ikhsan et al. The present study was conducted to investigate the prevalence and antibiotic resistance among Campylobacter jejuni in ulam at farms and retail outlets located in Kuala Terengganu, Malaysia. A total of 526 samples (ulam, soil, and fertilizer) were investigated for the presence of C. jejuni and the gene for cytolethal distending toxin (cdt) by using a multiplex PCR method.

Shenge, Kenneth C. et al. Although recent reports indicated that produce contamination with foodborne pathogens is widespread in Nigeria, the sources and magnitude of microbial contamination of fruits and vegetables on farms and in markets have not been thoroughly identified. To ascertain possible pathways of contamination, the frequency and magnitude of coliform and Escherichia coli contamination of tomatoes produced in northwest Nigeria was assessed on farms and in markets.

Balaguero, Alina N. et al. Overhead spray and brush roller (OSBR) treatment has been shown to remove significantly more Salmonella from tomato surfaces than flume treatment. However, OSBR is not widely used in tomato packing facilities compared with other commodities, and little is known about whether brushing causes microabrasions or other physical damage.

Lieberman, Vanessa M. et al. Whole and diced yellow onions (Allium cepa) were inoculated with five-strain cocktails of rifampin-resistant Escherichia coli O157:H7 or Salmonella and stored under conditions to simulate food service or consumer handling. The inoculum was grown in broth (for both whole and diced onion experiments) or on agar plates (for whole onion experiments).

Singh, Randhir et al. The purpose of this study was to determine the gene expression of Escherichia coli O157:H7 heat shocked in dairy compost. A two-step real-time PCR assay was used to evaluate the expression of stress and virulence genes in E. coli O157:H7 heat shocked in compost at 47.5°C for 10 min. Heat-shocked E.

Peng, Shengfeng et al. Eugenol is a major phenolic component with diverse biological activities. However, it is difficult to formulate into an aqueous solution due to poor water solubility, and this limits its application. In the present study, eugenol nanoliposomes (EN) were prepared by combining the ethanol injection method with the dynamic high-pressure microfluidization method. Good physicochemical characterizations of EN were obtained.

Giacometti, Federica et al. Two quantitative risk assessment (RA) models were developed to describe the risk of salmonellosis and listeriosis linked to consumption of raw milk sold in vending machines in Italy.

Palencia, Edwin R. et al.

Nielsen, Kristian Fog et al.In a recent article in Journal of Food Protection, Palencia and co-workers (34) published a survey on black Aspergillus species isolated from maize and peanuts reporting the production of some mycotoxins. An important claim in the article is their strains of Aspergillus niger
produce fumonisins B1 and B3. However, for many reasons, we consider the production of these two fumonisin isomers unlikely.

Davidson, P. Michael et al. Volume 77 of the Journal of Food Protection, published in 2014, contained 2,224 pages and 295 articles, which included 290 research papers (including research notes), and 5 review, general interest, and supplement papers (Table 1). By comparison, Volume 76 published in
