[Ab] Abstract:Iron fortification has been associated with a modest increase in diarrhea risk among children. Herein, we investigate the correction for this unwanted side effect with probiotic/prebiotic supplementation in weaning mice. Iron fortification with 250 ppm and 500 ppm ferrous sulfate for 30 days significantly increased the species richness of the mouse gut microbiota compared to controls. The 500 ppm-FeSO diet caused a significantly decreased abundance of potentially beneficial Lactobacillus. During infection with the foodborne pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium), mice on the 500 ppm-FeSO diet showed earlier appearance of poisoning symptoms, higher rates of weight and appetite loss, and lower survival rates, all of which were effectively reversed by supplementation with a probiotic (Lactobacillus acidophilus) or a prebiotic (inulin) for 7 days before infection. Iron fortification with 500 ppm ferrous sulfate also increased fecal shedding and spleen and liver load of viable S. Typhimurium, suggesting its promoting effect on pathogen colonization and translocation, and this negative effect was found to be well corrected by supplementation with Lactobacillus acidophilus or inulin. Light and transmission electron microscopic observation on the ileal villus structure revealed the histopathological impairment of the intestine by iron fortification with both 250 ppm and 500 ppm ferrous sulfate, and the intestinal lesions were markedly alleviated by supplementation with Lactobacillus acidophilus or inulin. These results provide experimental evidence for the increased diarrhea risk upon iron fortification with high pathogen load, and demonstrate that probiotic or prebiotic supplementation can be used to eliminate the potential harm of iron fortification on gut health.

[Ab] Abstract:Food poisoning caused by bacteria is a major cause of disease and death worldwide. Herein we describe the use of Janus micromotors as mobile sensors for the detection of toxins released by enterobacteria as indicators of food contamination. The micromotors are prepared by a Pickering emulsion approach and rely on the simultaneous encapsulation of platinum nanoparticles for enhanced bubble-propulsion and receptor-functionalized quantum dots (QDs) for selective binding with the 3-deoxy-d-manno-oct-2-ulosonic acid target in the endotoxin molecule. Lipopolysaccharides (LPS) from Salmonella enterica were used as target endotoxins, which upon interaction with the QDs induce a rapid quenching of the native fluorescence of the micromotors in a concentration-dependent manner. The micromotor assay can readily detect concentrations as low as 0.07 ng mL of endotoxin, which is far below the level considered toxic to humans (275 µg mL ). Micromotors have been successfully applied for the detection of Salmonella toxin in food samples in 15 min compared with several hours required by the existing Gold Standard method. Such ultrafast and reliable approach holds considerable promise for food contamination screening while awaiting the results of bacterial cultures in a myriad of food safety and security defense applications.

[Ti] Title:Verification and large scale clinical evaluation of a national standard protocol for Salmonella spp./Shigella spp. screening using real-time PCR combined with guided culture.

[Ab] Abstract:Salmonella spp./Shigella spp. are often associated with food poisoning and fecal-oral transmission of acute gastroenteritis that requires strict monitoring, especially among people who would handle food and water. In 2014, the National Health and Family Planning Commission of the P. R. China issued a national standard protocol (recommendatory) for the screening of Salmonella spp./Shigella spp.. However, its performance has not been fully studied. Whether it was suitable for use in our laboratory was still unknown. In the current study, the new protocol was first verified by various experiments and then its clinical performance was evaluated in about 20,000 stool samples over a three-year period. Verification results showed that the new protocol was highly specific and reproducible. Sensitivity (as defined as the lower limit of detection) of the new protocol at the PCR step was 10 CFU/mL and 10 CFU/mL for Salmonella spp. and Shigella spp., while that at the guided culture step was 10 CFU/mL and 10 CFU/mL, respectively. The large scale clinical evaluation indicated that the new protocol could increase the positivity rate by two fold and decrease the workload/median turnaround time significantly. In conclusion, the protocol was verified and evaluated and was proven to be a valuable platform for the rapid, specific, sensitive and high-throughput screening of Salmonella spp./Shigella spp.

[Ti] Title:Fate of Salmonella throughout Production and Refrigerated Storage of Tahini.

[Ab] Abstract:Tahini, a low-moisture food that is made from sesame seeds, has been implicated in outbreaks of salmonellosis. In this study, the fate of Salmonella was determined through an entire process for the manufacture of tahini, including a 24-h seed soaking period before roasting, subsequent grinding, and storage at refrigeration temperature. Salmonella populations increased by more than 3 log CFU/g during a 24-h soaking period, reaching more than 7 log CFU/g. Survival of Salmonella during roasting at three temperatures, 95, 110, and 130°C, was assessed using seeds on which Salmonella was grown. Salmonella survival was impacted both by temperature and the water activity (a ) at the beginning of the roasting period. When roasted at 130°C with a high initial a (≥0.90) and starting Salmonella populations of ∼8.5 log CFU/g, populations quickly decreased below detection limits within the first 10 min. However, when the seeds were reduced to an a of 0.45 before roasting at the same temperature, 3.5 log CFU/g remained on the seeds after 60 min. In subsequent storage studies, seeds were roasted at 130°C for 15 min before processing into tahini. For the storage studies, tahini was inoculated using two methods. The first method used seeds on which Salmonella was first grown before roasting. In the second method, Salmonella was inoculated into the tahini after manufacture. All tahini was stored for 119 days at 4°C. No change in Salmonella populations was recorded for tahini throughout the entire 119 days regardless of the inoculation method used. These combined results indicate the critical importance of a during a roasting step during tahini manufacture. Salmonella that survive roasting will likely remain viable throughout the normal shelf life of tahini.

[Ab] Abstract:The detection of Salmonella enterica serovar Typhimurium (S. Typhimurium) is very important for the prevention of food poisoning and other infectious diseases. Here we reported a simple and sensitive strategy to test S. Typhimurium by microchip capillary electrophoresis couple with laser-induced fluorescence (MCE-LIF) based on the specific reaction between the bacterium and corresponding aptamers. Based on the differences in charge to mass ratio between bacteria-aptamer complexes and free aptamers, a separation of the complexes and free aptamers could be obtained by MCE. The optimal parameters of the specific reaction including fluorescent dye concentration, Mg concentration, incubation time, and pH of incubation solution were carefully investigated. Meanwhile, a non-specific DNA was exploited as a contrast for the detection of S. Typhimurium. Under the optimal conditions, a rapid separation of the bacteria-aptamer complex and free aptamers was achieved within 135 s with a limit of detection (S/N = 3) of 3.37 × 10 CFU mL . This method was applied for the detection of S. Typhimurium in fresh milk samples and a recovery rate of 95.8% was obtained. The experimental results indicated that the specific aptamers are of enough biostability and the established method could be used to analyze S. Typhimurium in foods.

[Ab] Abstract:During May 2015, an increase in Salmonella Agona cases was reported from western Sydney, Australia. We examine the public health actions used to investigate and control this increase. A descriptive case-series investigation was conducted. Six outbreak cases were identified; all had consumed cooked tuna sushi rolls purchased within a western Sydney shopping complex. Onset of illness for outbreak cases occurred between 7 April and 24 May 2015. Salmonella was isolated from food samples collected from the implicated premise and a prohibition order issued. No further cases were identified following this action. Whole genome sequence (WGS) analysis was performed on isolates recovered during this investigation, with additional S. Agona isolates from sporadic-clinical cases and routine food sampling in New South Wales, January to July 2015. Clinical isolates of outbreak cases were indistinguishable from food isolates collected from the implicated sushi outlet. Five additional clinical isolates not originally considered to be linked to the outbreak were genomically similar to outbreak isolates, indicating the point-source contamination may have started before routine surveillance identified an increase. This investigation demonstrated the value of genomics-guided public health action, where near real-time WGS enhanced the resolution of the epidemiological investigation.

[Ab] Abstract:We herein describe a case with a neck abscess due to non-typhoidal (NTS). NTS habitually reside in our environment and colonize all animals including mammals. Colonizations of pigs, chickens, cows and sheep are important because food poisoning episodes in human are often associated with meat. Extra-intestinal infection due to NTS has numerous presentations and complications, with aortic aneurysms being common. A 26-year-old Japanese male complaining of left-sided neck swelling was referred to our hospital for a suspected deep neck abscess. An enhanced computed tomography scan of the neck revealed a low density lesion in the left-sided deep neck area, and consequently the patient underwent urgent incision and drainage. After this urgent operation, Choleraesuis was isolated from a greyish-white abscess. The patient ultimately recovered with antimicrobial administration, though re-incision for lymphadenectomy was necessary. The neck abscess may have developed because he had eaten raw meat. Furthermore, untreated diabetes mellitus was diagnosed at presentation. serovar Choleraesuis infections are rare in Japan. NTS are generally recognized as important pathogens in food poisoning globally, and attention is required to avoid the development of extra-intestinal infections. In Japan, the increasing lifestyle diversity in recent years highlights the importance of recognizing rare infections.

[Ab] Abstract:Each year in the United States, an estimated 525 000 infections, 2900 hospitalizations, and 82 deaths are attributed to consumption of pork. We analyzed the epidemiology of outbreaks attributed to pork in the United States reported to the Centers for Disease Control and Prevention (CDC) 1998-2015. During that period, 288 outbreaks were attributed to pork, resulting in 6372 illnesses, 443 hospitalizations, and four deaths. The frequency of outbreaks attributed to pork decreased by 37% during this period, consistent with a decline in total foodborne outbreaks. However, outbreaks attributed to pork increased by 73% in 2015 (19 outbreaks) compared with the previous 3 years (average of 11 outbreaks per year), without a similar increase in total foodborne outbreaks. Most (>99%) of these outbreaks occurred among people exposed in the same state. The most frequent etiology shifted from Staphylococcus aureus toxin during 1998-2001 (19%) to Salmonella during 2012-2015 (46%). Outbreaks associated with ham decreased from eight outbreaks per year during 1998-2001, to one per year during 2012-2015 (P < 0·01). Additional efforts are necessary to reduce outbreaks and sporadic illnesses associated with pork products.

[Ab] Abstract:INTRODUCTION: Salmonella Schwarzengrund is most frequently isolated from poultry meat and can cause human infections. S. Schwarzengrund was isolated from diarrheal patients in a food poisoning event in Nanjing, China. METHODS: Three strains isolated from patients were microbiologically confirmed as S. Schwarzengrund. Salmonella strains from spiced donkey meat were also confirmed as S. Schwarzengrund. Epidemiology investigation showed evidence of a correlation between the consumption of spiced donkey meat and those cases. Pulsed field gel electrophoresis, antibiotic susceptibility test and next generation sequencing (NGS) were employed to investigate this food poisoning event. RESULTS: The 3 strains isolated from patients and the strain isolated from the spiced donkey meat showed same results in PFGE, antibiotic susceptibility test and no SNPs were observed between these 4 strains in NGS analysis. DISCUSSION: NGS data could be used in the confirmation of an outbreak and in the tracing of contamination. However, this standard of defining an outbreak with NGS remained a challenge in practice. And the NGS data should be used in combination with other data in epidemiological investigation.

[Ab] Abstract:has represented the most common and primary cause of food poisoning in many countries for at least over 100 years. Its detection is still primarily based on traditional microbiological culture methods which are labor-intensive, extremely time consuming, and not suitable for testing a large number of samples. Accordingly, great efforts to develop rapid, sensitive and specific methods, easy to use, and suitable for multi-sample analysis, have been made and continue. Biosensor-based technology has all the potentialities to meet these requirements. In this paper, we review the features of the electrochemical immunosensors, genosensors, aptasensors and phagosensors developed in the last five years for Salmonella detection, focusing on the critical aspects of their application in food analysis.
