FOODS 01/06/21 Reusable Plastic Crates (RPCs) for Fresh Produce (Case Study on Cauliflowers): Sustainable Packaging but Potential Salmonella Survival and Risk of Cross-Contamination. The handling of fresh fruits and vegetables in reusable plastic crates (RPCs) has the potential to increase the sustainability of packaging in the fresh produce supply chain.
However, the utilization of multiple-use containers can have consequences related to the microbial safety of this type of food. The present study assessed the potential cross-contamination of fresh cauliflowers with Salmonella enterica via different contact materials (polypropylene from RPCs, corrugated cardboard, and medium-density fiberboard (MDF) from wooden boxes). Additionally, the survival of the pathogenic microorganism was studied in cauliflowers and the contact materials during storage. The life cycle assessment (LCA) approach was used to evaluate the environmental impact of produce handling containers made from the different food-contact materials tested. The results show a higher risk of cross-contamination via polypropylene compared with cardboard and MDF. ►▼ Show Figures Graphical abstract. FRONT. SUSTAIN.

Introduction Classification of bacterial pathogens into species has traditionally been an essential prerequisite for many aspects of infection control and food safety.
Consequently, control measures, regulations, industry specifications, and other guidance documents for foodborne pathogens typically specify a pathogen species (or genus) as target. For example, current Codex Alimentarius guidelines recommend absence of Salmonella in two 375 g samples for infant formula (FAO, 2020). For other ready-to-eat (RTE) foods, absence in smaller samples size (e.g., 25 g) is typically expected. However, there is increasing evidence for Salmonella, as well as other foodborne pathogens, that subgroups, serovars, and/or clonal groups within a given species may differ considerably in their ability to cause human disease.

Using new tools, researcher discovers bacterial diversity in freshwater Monitoring salmonella in the environment is critical because contaminated freshwater used to irrigate crops can transfer pathogenic bacteria to fresh produce, causing illness and even death.
But University of Georgia researcher Nikki Shariat believes traditional salmonella surveillance methods have been missing the big picture. Salmonella colonies growing on red indicator plates. (Submitted photo) Shariat, an assistant professor of population health at UGA’s College of Veterinary Medicine, has found that salmonella populations in freshwater are more diverse than previously thought. In a recent study published in Applied and Environmental Microbiology, Shariat, principal investigator on the project, detailed not only the change in salmonella populations in the Susquehanna River Basin over time but also uncovered hidden populations that have, until now, gone undetected.

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).

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.
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 . 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. There are numerous mechanisms of the transmission of zoonoses, and some diseases are transmitted in various ways, which significantly hinders the diagnostic process (Figure 1) .

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.

FRONTIERS IN VETERINARY SCIENCE 14/06/17 The Potential Link between Thermal Resistance and Virulence in Salmonella: A Review. 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).
In order for Salmonella to survive and colonize the human body, it must overcome multiple non-specific host defenses encountered within the host such as low pH, limited nutrient availability and in poultry birds, a high body temperature (42°C).

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).

FRONTIERS IN MICROBIOLOGY - NOV 2013 - Mechanisms of survival, responses, and sources of Salmonella in low-moisture environments. Introduction Drying is a traditional method that has been used to preserve food and to this day low-moisture foods have constituted a substantial part of our diet. Foods in this category have a long shelf life and are usually stable for years. Low- and intermediate-moisture foods have a reduced water activity (aw). The term aw was originally applied by the pharmaceutical and food industries as a quantitative measure used in the determination of the shelf life of a product. aw can be defined as the ratio of the vapor pressure of water in a food matrix compared to that of pure water at the same temperature (Labuza, 1980). Pure distilled water has an aw of 1 and low-moisture products have a reduced value relative to this. The availability of water for biological reactions can be reduced by a number of methods such as freezing, the physical removal of water (such as spray drying), or by the addition of solutes such as salt and sugar (Brown, 1976).
