Research Publications (Food Safety)

The Food Safety Publications tracks research that is published across national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. The research publications are tracked across six categories: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, Produce Safety, and Viruses. Articles produced by USDA Grant Funding Agencies and FDA Grant Funding Agencies are also tracked.

    • The virulent genes expressed in Salmonella are one primary contributing factor leading to the high morbidity and mortality of salmonellosis in humans. This factor plays a role in infection of the host and transmission of disease. In this study, a total of 265 samples were collected from farmers' market in Xuzhou, Jiangsu Province, China, including 205 pork samples and 60 chicken samples.

    • Non-typhoidal Salmonella (NTS) strains are among the major foodborne pathogens with emerging multidrug-resistant phenotypes. In this study, antimicrobial susceptibilities of a collection of  Salmonella isolates (n=54) recovered from poultry and bivalve molluscs were performed. The study also investigated the virulence and resistance genes profiling as well as the phylogenetic relationships through PFGE and ERIC/PCR fingerprinting.

    • Fri, 09/23/2022 - 04:00
    • Food Science and Biotechnology
    • Staphylococcus aureus is a gram-positive foodborne pathogen capable of forming strong biofilms. This study identified that anti-biofilm natural compound against S. aureus. Sinomenine, a natural compound, showed significantly reduced biofilm formation (31.97–39.86%), but no effect on bacterial growth was observed. The dispersion of preformed biofilms was observed by confocal laser scanning microscopy (CLSM).

    • As part of a program to reduce numbers of the human pathogen Campylobacter on retail chickens twenty-two broiler processing lines, representing over 90% of United Kingdom (UK) production, were characterized by enumerating Campylobacter on pooled neck skins after the exsanguination, scalding, defeathering, evisceration, crop removal, inside-outside washing, and air-chilling stages of processing.  Sixteen of the processing lines investigated showed significant (p<0.05) reductions in Campylob

    • Infection and Immunity
    • Infection and Immunity, Ahead of Print. Campylobacter jejuni is the most common cause of bacterial foodborne gastroenteritis and holds significant public health importance. The continuing increase of antibiotic-resistant Campylobacter necessitates the development of antibiotic-alternative approaches to control infections in poultry and in humans. Here, we assessed the ability of E. coli Nissle 1917 (EcN; free and chitosan-alginate microencapsulated) to reduce C.

    • mBio, Ahead of Print. Diverse bacterial volatile compounds alter bacterial stress responses and physiology, but their contribution to population dynamics in polymicrobial communities is not well known. In this study, we showed that airborne volatile hydrogen cyanide (HCN) produced by a wide range of Pseudomonas aeruginosa clinical strains leads to at-a-distance in vitro inhibition of the growth of a wide array of Staphylococcus aureus strains.

    • The delayed treatment of pediatric periorbital cellulitis may have severe consequences. In addition, the antibiotic efficacy against causative bacteria may change over time, and it is important to understand the appropriate antibiotic options for effective treatment in pediatric patients. We compared the changes in cultured bacteria and drug susceptibility tests between two decades, 2010&ndash;2019 and 2000&ndash;2009, to establish antibiotics for empirical use.

    • Thu, 09/22/2022 - 04:00
    • Waste Management & Research
    • One 25-kg dog produces about 500 g of excrement per day. Excrement is a potentially hazardous material, as it may contain pathogenic microorganisms. Our samples were tested for the presence of thermotolerant coliform bacteria, Enterococcus spp., Escherichia coli and Salmonella spp., which are indicators of faecal contamination, as well as for the presence of helminths and their eggs. During the experiment, it was observed whether these microorganisms could be eliminated by vermicomposting.

    • Canadian Journal of Microbiology
    • Salmonella enterica and Escherichia coli use the inner membrane transporter DctA to import the pyrimidine biosynthetic pathway intermediate orotate from the environment. To study the regulation of dctA expression, we used an S. enterica serovar Typhimurium pyrimidine auxotroph to select a mutant that could grow in an otherwise nonpermissive culture medium containing glucose and a low concentration of orotate.

    • Frontiers in Microbiology
    • We studied the biodegradation of oily sludge generated by a petroleum plant in Bahrain by a bacterial consortium (termed as AK6) under different bioprocess conditions. Biodegradation of petroleum hydrocarbons in oily sludge (C11-C29) increased from 24% after two days to 99% after 9 days of incubation in cultures containing 5% (w/v) of oily sludge at 40°C. When the nitrogen source was excluded from the batch cultures, hydrocarbon biodegradation dropped to 45% within 7 days.
