FRONT. MICROBIOL 27/08/19 A Comprehensive Antimicrobial Activity Evaluation of the Recombinant Microcin J25 Against the Foodborne Pathogens Salmonella and E. coli O157:H7 by Using a Matrix of Conditions. Introduction The most notorious and common pathogenic Escherichia coli (E. coli) O157:H7, Salmonella Typhimurium and Salmonella Pullorum strains are primary enteric pathogens that not only inhibit human and animal health but also cause food poisoning and food-related epidemics around the world (Sable et al., 2000; Ma et al., 2016; Fan et al., 2017). Especially, fresh produce, such as milk, meat, and egg, is increasingly related to the incidence of foodborne illness, and outbreaks associated with fresh produce consumption by human or animals have risen substantially recently (Centers for Disease Control and Prevention [CDC], 2010, 2013).

As reported, from 1990 to 2005, around 800 outbreaks sickened over 34,000 people because of produce-associated foodborne illness (DeWaal and Bhuiya, 2007). The effects of recombinant AMP MccJ25 on ETEC K88 were examined previously, but this research did not determine efficacy for different conditions and strains (Yu et al., 2018a).

BIORXIV 05/04/19 The speciation and hybridization history of the genus Salmonella. FOOD SAFETY NEWS 15/01/19 Researchers uncover how Salmonella infects plants before harvest. Scientists in India have discovered how Salmonella enters plants to cause pre-harvest contamination of produce. Most Salmonella outbreaks are linked to contamination from post-harvest handling and transportation but the bacterium can enter the plant earlier from contaminated soil. Salmonella can reach the soil from manure containing animal feces or contaminated irrigation water. The study from the Indian Institute of Science (IISc) and the University of Agricultural Sciences (UAS), Bengaluru looked at tomato plants and was published in the journal BMC Plant Biology.

Researchers found Salmonella enters through a gap created when a lateral root branches out from the plant’s main root and that it can penetrate the deeper layer of the root. They studied how different types of bacteria including Salmonella colonize the roots of tomato plants. While other bacteria were spread across the root, Salmonella clustered around areas where lateral roots emerge.

Silver-copper has longer microbial inactivation kinetics than ClO2 and NaClO.

Bacterial cell history did not affect the efficacy of studied sanitizers. Organic load, water temperature, and pathogen attachment/release affect sanitizers. Minimum effective sanitizer concentrations are low but help control water quality. Abstract Washing fresh produce with potable water helps to remove microorganisms, providing about a 1- to 2-log reduction, but this process can also pose an opportunity for cross-contamination of bacteria in the washing tank.

Introduction Zoonoses, or diseases of animal origin, are defined as diseases transmitted between animals and humans as a consequence of a direct contact, indirect environmental contact, or through food [1]. Among recognised pathogens causing human diseases, almost 60% are of animal origin. They cause such diseases as toxoplasmosis, anthrax, rabies, Ebola haemorrhagic fever, severe acute respiratory syndrome (SARS), and primary HIV infection [2,3]. Already in 1906, doctor Silvio J. Bonansea described in his paper titled “Veterinary Hygiene Applied to the Protection of Man against Zoonoses” how animal health and hygiene are important for the production of safe and healthy meat and milk [4].

Almost 50 years later, in November 1950 in Geneva, during the first meeting of the Expert Group on Zoonoses formed by the World Health Organisation (WHO) and the United Nations Food and Agriculture Organisation (FAO), a list of 86 diseases transmitted from animals to humans was identified.

A number of large scale Salmonella outbreaks have been associated with low aw food products where the significant causal factor was most likely cross-contamination.

These studies sought to both: assess Salmonella survival and survival mechanisms when dried onto stainless steel under simulated food factory conditions, and to develop enhanced factory control approaches for this pathogen. Fifteen isolates of Salmonella survived 30 days under desiccation and one strain survived for one year and potentially could survive longer. Differences in the survival between different Salmonella serotypes, and isolates of the same serotype (S.

Abstract Produce has become a major source of foodborne illness, and may become contaminated through surface water irrigation. The objectives of this study were to (i) determine the frequency of verotoxigenic E. coli (VTEC), Listeria monocytogenes, and Salmonella in surface waters used for irrigation in the Lower Mainland of British Columbia, (ii) assess the suitability of fecal coliforms and generic E. coli as hygiene indicators, and (iii) investigate the correlations of environmental factors with pathogen occurrence. Water samples were collected semi-monthly for 18 months from seven irrigation ditches across the Serpentine and Sumas watersheds. VTEC colonies on water filters were detected using a verotoxin colony immunoblot, and the presence of virulence genes vt1 and vt2 was ascertained via multiplex PCR. Detection of L. monocytogenes and Salmonella was completed using standard, Health Canada Compendium of Analytical Methods. Copyright: © 2017 Falardeau et al.

Introduction Salmonella is a Gram-negative foodborne pathogen that is a major concern for the food industry and public health authorities because of its capability to cause both widespread contamination and infection within the United States (US) and worldwide (1–5). An estimated one million cases of Salmonella-related illnesses occur annually within the US. For example, in 2014, Salmonella was responsible for 10 multistate outbreaks with approximately 1,000 reported outbreak cases (3, 6). Numerous strategies have been implemented to reduce Salmonella transmission, contamination, and infection. Salmonella infections are most commonly acquired through ingestion of contaminated foods such as eggs and poultry meat (7). Salmonella can colonize the small intestines of poultry birds, along with the cecum, without demonstrating any symptoms related to Salmonella infections.

Introduction Infant foods, such as baby cereals and powdered infant milk formulae (PIF), can act as vectors for pathogenic microorganisms of importance to human health as technology is currently unavailable to manufacture these foods as sterile products. Thus, despite the implementation of good manufacturing practices PIF may, on occasion, become contaminated with pathogens during production. Those pathogens that present the greatest threat to infant health include Cronobacter species (formerly known as Enterobacter sakazakii) and Salmonella enterica, two bacterial genera designated by the World Health Organisation (WHO) as Class A pathogens.

Following the consumption and ingestion of contaminated foods, clinical signs of infection include gastroenteritis which can progress to bacteraemia and meningitis (Cahill et al., 2008). Numerous Salmonella outbreaks associated with contaminated infant foods have been documented since the 1950s and 1960s (Brouard et al., 2007). Materials and Methods. FRONTIERS IN MICROBIOLOGY 20/10/16 Effectiveness of Washing Procedures in Reducing Salmonella enterica and Listeria monocytogenes on a Raw Leafy Green Vegetable (Eruca vesicaria) Introduction Vegetables are an important source of dietary fiber, vitamins and minerals, have low energy density and provide a range of nutrients that are required to regulate the body’s metabolic functions. For these reasons, dietary guidelines recommend a high intake of vegetables (WHO/FAO, 2003). However, due to their high surface/weight ratio and relatively high pH, salad vegetables host large microbial populations, particularly bacteria, which contribute to the natural decay of vegetative organs detached from the plant (Ragaert et al., 2007).

Human pathogens such as Listeria monocytogenes, Salmonella, and Escherichia coli O157:H7 can contaminate foodstuffs both during plant cultivation and processing (Francis et al., 1999; Brandl, 2006; Franz and van Bruggen, 2008). The risk derived from contaminated foodstuffs is increased for YOPIs (Young, Old, Pregnant, Immunocompromised) due to their high susceptibility and, thus, the possibility for disease to be more severe.
