Preliminary Incidence and Trends of Infections with Pathogens Transmitted Commonly Through Food - Foodborne Diseases Active Surveillance Network, 10 U.S. Sites, 2016-2019.

This report summarizes preliminary 2019 data and describes changes in incidence compared with that during 2016-2018. The incidence of enteric infections caused by these eight pathogens reported by FoodNet sites in 2019 continued to increase or remained unchanged, indicating progress in controlling major foodborne pathogens in the United States has stalled. Campylobacter and Salmonella caused the largest proportion of illnesses; trends in incidence varied by Salmonella serotype. Widespread adoption of whole genome sequencing (WGS) of bacteria has improved the ability to identify outbreaks, emerging strains, and sources of pathogens. To maximize the potential of WGS to link illnesses to particular sources, testing of isolates by clinical and public health laboratories is needed. Reductions in Salmonella serotype Typhimurium suggest that targeted interventions (e.g., vaccinating chickens and other food animals) might decrease human infections. Reducing contamination during food production, processing, and preparation will require more widespread implementation of known prevention measures and of new strategies that target particular pathogens and serotypes.

(BfR Federal Institute for Risk Assessment) To make food even safer for humans, experts from scientific institutions, food regulatory authorities and the business community will discuss current developments and strategies at the 'Zoonoses and Food Safety' Symposium at the German Federal Institute for Risk Assessment (BfR) on 4 and 5 November 2019, in Berlin-Marienfelde. Because some micro-organisms in food can cause health problems. Campylobacter in raw milk, salmonella in eggs or listeria in ready-to-eat foods often lead to outbreaks affecting numerous patients.

Abstract In Japan, from 2000 to 2018, for Vibrio parahaemolyticus and Salmonella food poisonings, the annual number of the outbreaks and that of the patients decreased exponentially though the size of the individual outbreaks (the number of patients per outbreak) tended to become larger. For food poisonings caused by Campylobacter, the annual number of the outbreaks increased exponentially while the outbreak size became smaller and the annual number of the patients remained almost unchanged. For food poisoning caused by norovirus, both the number of the outbreaks and that of the patients remained high throughout. ...

CONCLUSION: The occurrence of genetically similar diarrheagenic E. coli in both groups of children, likewise resistant to these agents, underscores the importance of establishing strategies for the prevention of outbreaks, especially among low-income households.

In this study, a transposon mutagenesis approach was applied to reveal the factors involved in resistance to oxidative stress, and the biofilm formation among mutants and WT strains were further detected using crystal violet staining (CVS), scanning electron microscopy (SEM), and confocal laser scanning microscopy (CLSM) to reveal potential relationship between oxidative stress and biofilm formation. Materials and Methods The Development of Mutants Library The procedure of transposon mutagenesis approach was performed as described by Zhang et al. (2018). Screening of Mutants Tolerance to Oxidative Stress For screening...

This report summarizes preliminary 2018 data and changes since 2015. During 2018, FoodNet identified 25,606 infections, 5,893 hospitalizations, and 120 deaths. The incidence of most infections is increasing, including those caused by Campylobacter and Salmonella, which might be partially attributable to the increased use of culture-independent diagnostic tests (CIDTs). The incidence of Cyclospora infections increased markedly compared with 2015-2017, in part related to large outbreaks associated with produce (1). More targeted prevention measures are needed on produce farms, food animal farms, and in meat and poultry proce...

Conclusion Starter cultures are an important tool that contributes to ensure the safety of fermented meat products. Indeed, the microorganisms that constitute starter cultures may inhibit or reduce the growth of spoilage and/or pathogenic populations through mechanisms, such as production of certain metabolites or competitive exclusion. Thus, the use of starter cultures may reduce the need for chemical additives, such as nitrites and nitrates. Furthermore, the lower residual levels of nitrates and nitrites detected in fermented meat products inoculated with starter cultures are due to the ability of starters to metabolize...

In conclusion, association rule mining is an effective tool for identifying patterns of multidrug resistance within antimicrobial susceptibility testing data and evaluating the statistical and biological significance of the patterns. Rule quality measures used to sort and differentiate rules should be tested using resampling procedures to minimize the false discovery rate. Rule mining identified consistent multidrug resistance patterns involving beta-lactams, sulfisoxazole, tetracycline, gentamicin, and streptomycin in E. coli isolated from chicken carcasses and meat between 2004 and 2012. The generally low rule overlap su...

Abstract Zoonoses such as Brucella, Mycobacterium bovis, Campylobacter, Salmonella, Escherichia coli, Listeria, etc. are spread by ingestion of contaminated unpasteurised milk products (from infected cattle) and result in infectious outbreaks, hospitalisations and mortality. In Southeast Asian countries, raw goat's milk is sometimes used for dengue infection-associated thrombocytopenia; however, evidence to support this sociocultural practice is lacking. A peak incidence of brucellosis cases may occur after a dengue season in communities where this practice is prevalent. PMID: 30895885 [PubMed - as supplied by publisher]
