    • Journal of Food Protection
    • The aim of the present study was to investigate the ability of natural plant-derivate (flavonoid compounds) products to reduce and/or inhibit the biofilm-forming ability of Listeria monocytogenes. A collection of 500 synthetic and natural flavonoids were tested on strains of L. monocytogenes for their antimicrobial and anti-biofilm activity.

    • Journal of Food Protection
    • Salmonella continues to be a significant cause of foodborne illnesses in human medicine. The Centers for Disease Control and Prevention reported Salmonella as the second leading cause of foodborne illness in the United States, and the leading cause of both hospitalizations and deaths. Salmonella enterica 4,[5],12:i:- (STM) is a monophasic variant of S. Typhimurium and it is an emerging threat to both human and animal health.

    • Journal of Food Protection
    • Bacillus weihenstephanensis can grow at refrigeration temperature and cause food poisoning. It has been isolated from liquid whole egg products. The moderate heat used for pasteurization of liquid egg products is ineffective for killing spore-forming bacteria including Bacillus. Available predictive models and a pretrial study in broth suggested the potential for growth of Bacillus spp. under the tested conditions.

    • Journal of Food Protection
    • Toxoplasma gondii is the causative agent of the parasitic disease toxoplasmosis, which is an important food borne zoonosis. Eating undercooked meat of infected animals has been considered the major transmission route of T. gondii to humans. The present study evaluates the efficacy of domestic freezing on the inactivation of T. gondii bradyzoites in raw and dry-cured ham. Meat (raw and dry-cured ham) of a pig experimentally orally inoculated with 4,000 oocysts of T.

  9. Consumers Awareness of the Message Not to Wash Raw Poultry, Current Practices, and Barriers to Following that Message

    • Thu, 12/23/2021 - 04:01
    • Journal of Food Protection
    • There are an estimated 47.8 million cases of foodborne illness in the U.S. each year. Raw poultry is the most common single commodity food associated with foodborne illness. The practice of washing raw poultry is highly prevalent among consumers despite the significant cross contamination risk. Previous educational campaigns have attempted to reduce the prevalence of washing raw poultry; however, there is limited information on how successful they have been in changing consumer behavior.

    • The use of antimicrobials in formulations of ready-to-eat meat and poultry products has been identified as a major strategy to control Listeria monocytogenes . The USDA-FSIS recommends no more than 2-logs of Listeria outgrowth over the stated shelf life if antimicrobials are used as a control measure for a product with post-lethality environmental exposure. This study was designed to understand the efficacy of a clean label antimicrobial against the growth of L.

  11. The Food Safety Risks of Harvesting Dropped and Drooping Produce: A Review

    • Fri, 12/17/2021 - 04:01
    • Journal of Food Protection
    • The Food Safety Modernization Act’s Produce Safety Rule sets forth minimum standards for fruit and vegetable production in the U.S. One provision states that growers must not harvest dropped produce, as damage or ground contact may contaminate produce. An unpublished survey of 2020 food safety inspections conducted by the Northeast Center to Advance Food Safety identified handling of dropped covered produce as a common misunderstanding and non-compliance issue among Northeast growers.

    • Fri, 12/17/2021 - 04:01
    • Journal of Food Protection
    • The neutropenic diet has long been a dietary prescription for immunocompromised patients. Its effectiveness and consistency, unfortunately, have been constantly challenged. Researchers and healthcare policymakers call for liberalization of neutropenic diet, which shifts risk management strategies from excluding claimed “high-risk” food items to focus on safe food handling. The responsibility of food safety falls on foodservice workers in a healthcare setting.

    • Journal of Food Protection
    • Fish oil inclusion into a dry pet food provides a source of long-chain omega-3 fatty acids. Polyunsaturated fatty acids (PUFA) in fish oil have antibacterial activity against various foodborne pathogens such as Salmonella and pathogenic Escherichia coli. The purpose of this study was to determine the effect of temperature applied to dry pet food kibbles on the antimicrobial activity of Menhaden fish oil against Salmonella spp.

    • Journal of Food Protection
    • The disinfection efficacy and mechanism of slightly acid electrolyzed water (SAEW) on Cronobacter sakazakii were investigated. SAEW solutions in three concentrations were carried on C. sakazakii which decreased in a range of 23%-55% in 2 minutes. The propidium iodide (PI) uptake and electronic microscopy (SEM) images indicated that SAEW treatment damaged cell integrity and changed membrane permeability with leaking nucleic acid (109.7%), intercellular protein (692.3%) and K + (53.6%).

    • Journal of Food Protection
    • There is limited examination about COVID-19-related food handling concerns and practices that cause chemical or microbial contamination and illness, particularly among those with food insecurity. We investigated consumer food handling concerns and practices during the COVID-19 pandemic, and whether they differed by food insecurity status. An online survey was distributed among Chicago, Illinois residents between July 15-August 21, 2020 (N=437).

    • Fri, 12/03/2021 - 04:02
    • Journal of Food Protection
    • Reference methods developed for L. monocytogenes are commonly used for Listeria spp. detection. Improved method performance data are needed, since the genus Listeria has expanded from 6 to 26 species and now includes several Listeria sensu lato species, which can show phenotypes distinct from Listeria sensu stricto . Here, we evaluated growth of 19 Listeria spp., including 12 recently described sensu lato species, using the media specified by (i) the U.S.

    • Journal of Food Protection
    • Composted or heat-treated Biological Soil Amendments of Animal Origin (BSAAO) can be added to soils to provide nutrients for fresh produce. These products lower the risk of pathogen contamination of fresh produce when compared with use of untreated BSAAO; however, meteorological conditions, geographic location, and soil properties can influence the presence of pathogenic bacteria, or their indicators (e.g., generic E. coli) and allow potential for produce contamination.

  22. Characterization of bacteria and antibiotic resistance in commercially-produced cheeses sold in China

    • Fri, 12/03/2021 - 04:01
    • Journal of Food Protection
    • The consumption of cheese in China is increasing rapidly. Little is known about the microbiota, the presence of antibiotic-resistant bacteria, or the distribution of antibiotic resistance genes (ARGs) in commercially-produced cheeses sold in China. These are important criteria for evaluating quality and safety. Thus, this study assessed the metagenomics of fifteen types of cheese using 16S rRNA gene sequencing. Fourteen bacterial genera were detected.
