On the trail of pathogens in meat, eggs and raw milk

(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.

In conclusion, the results suggest that, because of its bioactivity including the antioxidant, antimicrobial, and enzyme inhibition properties, the D. macrolepis can be accepted as a promising and natural source for the industrial applications. The present study is the first study, in which the bioactive components and the antioxidant, antimicrobial, and enzyme inhibition properties of endemic D. macrolepis plant were determined.

We examined our primary care birth cohort of 158,510 pediatric patients, of whom 214 patients met 2017 FPIES diagnostic criteria. We measured the influence of FPIES on developing subsequent atopic disease.ResultsPediatric FPIES incidence was between 0.17% and 0.42% depending on birth year. As in prior reports, most patients had an acute presentation (78%), and milk, soy, oat, rice, potato, and egg were common triggers. The mean age of diagnosis was 6.8 months. Atopic comorbidity was higher in patients with FPIES compared with healthy children (AD, 20.6% vs 11.7%; IgE-FA, 23.8% vs 4.0%; asthma, 26.6% vs 18.4%; AR, 28.0% vs 16.7%; P

ConclusionThis study demonstrates that ESAT6 bound with TLR2 can activate iNOS/NO and ROS signalings to reduce the trimethylation of H3K27 resulting in the increment of EMMMs expression that is beneficial to the transition of macrophages into epithelioid macrophages. However, hypoxia can inhibit this transition event. This study has provided new evidence of pathogenesis of granuloma caused by Mtb and also proposed new ideas for the treatment of TB.

CONCLUSION: Enterococcus spp. with susceptibility to limited antibiotics was one of the main pathogens in Korean IAIs, along with E. coli and Klebsiella spp., which were highly susceptible to imipenem, amikacin, and piperacillin/tazobactam. Meanwhile, the low susceptibilities of E. coli or Klebsiella spp. to amoxicillin/clavulanate, advanced-generation cephalosporins, and ciprofloxacin should be considered when determining empirical antibiotic therapy in clinical practice.

Mahgoub, Emilie DumasAbstractPlants have been traditionnally used for centuries in cheese manufacturing, either for their aromatic properties or as technological auxiliaries (e.g. milk-clotting enzyme preparations, cheese wrappers). Some of these plants are known to have antimicrobial and / or antioxidant properties and could also act as natural preservatives for raw milk and derived dairy products.This review examined the traditional uses of plants ...

NgapoAbstractThe final destination of the large volumes of horse meat produced in Mexico is not apparent. The current study therefore aimed to determine if horse meat is sold fraudulently under the guise of beef in Mexico and the levels of clenbuterol residues in samples. While more than a quarter of the sellers interviewed claim to know of suppliers for horse meat, only 7% would like to sell ...

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...

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]

Conclusions: Our model-based estimates suggest that reducing pathogen prevalence and concentration in source manure would reduce the risk of AGI from exposure to manure irrigation, and that increasing the distance from irrigated manure (i.e., setbacks) and limiting irrigation to times of low wind speed may also reduce risk. https://doi.org/10.1289/EHP283 Received: 30 March 2016 Revised: 07 March 2017 Accepted: 13 March 2017 Published: 16 August 2017 Address Correspondence to M.A. Borchardt, USDA-ARS, 2615 Yellowstone Dr., Marshfield, WI 54449 USA.
