The current study investigated the emergence of multidrug-resistance (MDR), extended-spectrum beta-lactamase (ESBL)-producing Salmonella enterica serovar Heidelberg in broiler chickens and workers in poultry farms. A total of 33 S. Heidelberg isolates were recovered; 24 from the broiler cloacal swabs and 9 from the farm workers. All the S. Heidelberg isolates were tested for susceptibility to 11...

Melons are perishable fruit of high food safety risk, grown in contact with soil and soil-borne organisms. To assess whether food safety risk could be augmented by the presence of soil-borne fungi, this study investigated the relationship between Fusarium spp. that were isolated from the surface of melon and the foodborne pathogen Salmonella enterica. In four repeated trials, rind discs from...

Polyphenols are a group of active ingredients in olive oil, and have been reported to exhibit antioxidant activity. Salmonella enterica subsp. enterica serovar Typhimurium (Salmonella Typhimurium) and Staphylococcus aureus are common foodborne pathogens causing serious infections and food poisoning in humans. This study was conducted to analyze the antibacterial activity of olive oil polyphenol...

Eggs are a highly nutritious food source used in a wide range of food products. In Australia, eggs are a frequent source of foodborne salmonellosis outbreaks, associated with eggshell contamination with Salmonella enterica serovar Typhimurium (ST). Despite their potentially hazardous nature, raw eggs are often used and consumed in mayonnaise, mousse, ice cream and eggnog. The aim of this study...

Bacillus cereus sensu lato (s.l.) is a group of bacteria commonly found in diverse environments, including foods, with potential to cause emesis and diarrhea. In Colombia, it is one of the main foodborne pathogens. The aim of this study was to determine the genomic and toxigenic heterogeneity of B. cereus s.l. isolated from ready-to-eat foods and powdered milk collected in day care centers of...

This study evaluated the acid tolerance response (ATR) of two strains of Listeria monocytogenes (serotype 1/2a and 4b) and one strain of Listeria innocua under different mildly acid conditions. Cells were incubated in combinations of three concentrations of lactic acid medium (3, 4.75, and 15 mM) and three external pH's (pHex 5.0, 6.0, and 6.5), plus, a HCl control, and a blank control (pH 7.4)....

Due to the increasing number of studies reporting the detection of antimicrobial-resistant isolates of Listeria monocytogenes, we sought to determine the antimicrobial susceptibility of L. monocytogenes isolates collected in Italy and find potential correlations to their serotypes and multilocus sequence types (MLST). The antimicrobial susceptibility of 317 L. monocytogenes isolates collected...

Campylobacter jejuni is the leading cause of human foodborne enteritis worldwide. Poultry products are regarded as the main source of human campylobacteriosis. Strategies are being developed to reduce colonization of poultry by Campylobacter. The membrane transport protein CjaA was reported to stimulate mucosal immune responses, which can reduce the C. jejuni load in chickens. In this study, oral...

Vibrio parahaemolyticus is a marine bacterium that causes foodborne diarrhea. Many seafood restaurants keep live fish and shellfish in fish tanks for use in raw seafood dishes; thus, the present study aimed to investigate the prevalence, antibiotic-resistance, and virulence characteristics exhibited by V. parahaemolyticus detected in restaurant fish-tank water samples collected in Seoul, South...
