Journal of Food Safety, EarlyView. There is a growing consensus that plant-derived antimicrobials may be a safe and effective alternative to synthetic chemical preservatives against foodborne pathogens. This study aims to investigate the potential application of the stems and leaves of Astragalus membranaceus (AMSL) in food preservation.

Journal of Food Safety, EarlyView. Green thin films for food packaging are essential and growing in recent years to reduce the dependence on petroleum-derived plastics. In this study, the glycerol-plasticized chitosan film incorporated with 1–3% of crude Piper betel Linn.

Journal of Food Safety, EarlyView. This study develops a rapid lateral flow assay (LFA) that uses immunomagnetic nanoparticles (IMNPs) to detect mango major allergen (Man i1) in food products. Monoclonal antibodies (2F1 and 21A5) were prepared; mAb-2F1 was modified on the surface of IMNPs and mAb-21A5 was immobilized on the test line of the LFA strips. Following optimization, the limit of detection (LOD) of this developed LFA was 6.2 ng/mL for rMan i1 with a linear range of 5–100 ng/mL.

Journal of Food Safety, EarlyView. With the enhanced use of chemical preservatives and the survival of foodborne pathogens, lactic acid bacteria and its metabolic product have received increased attention as a potential food preservative. Even though the antibacterial property of lactic acid bacteria is well known, its antifungal property and application in food preservation have not been widely exploited.

Journal of Food Safety, EarlyView. This study analyzed raw (unpasteurized) dairy milk samples from farms, milk vendors, and shops in the Peshawar region of Pakistan for the prevalence of pathogenic multidrug-resistant (MDR) Escherichia coli. During August 2018–September 2019, 100 cow′s milk samples from 10 subregions of the Town-3 district were tested for the prevalence of E. coli and of Shiga toxin–producing serotype O157: H7 using various biochemical, morphological, and molecular tests.

Journal of Food Safety, EarlyView. Vibrio vulnificus is one of the major cause of foodborne illness related to seafood consumption. This study aimed to develop monoclonal antibodies (MAbs) to enable rapid detection and monitoring food contamination of this pathogen. Five groups of MAbs against V. vulnificus were generated from a mouse immunized with a clinical isolate of V. vulnificus, heat and formalin-inactivated whole cells. The first two groups of MAbs were species-specific to V.

Journal of Food Safety, EarlyView. The objective of this study was to investigate the effect of dielectric-barrier discharges plasma (DBDP) treatment against Escherichia coli O157:H7 and Staphylococcus aureus in different types of food matrix. Dried julienned squid (DS), squid powder (SP), beef jerky (BJ), and beef powder (BP) were inoculated with E. coli O157:H7 or S. aureus and treated with DBDP. The treatment voltage varied at 6.11, 9.25, and 11.86 kV.

Journal of Food Safety, EarlyView. Watercored apple is a type of fruit with unique flavor and visual appearance. However, the watercore feature of apples will gradually disappear or develop internal disorders during storage, which would compromise their commercial value.

Journal of Food Safety, EarlyView. Hydroponics was considered an effective method to practice sustainable agriculture. However, very few studies were carried out related to the microbial and heavy metal safety assessment of hydroponically grown produce. So the microbial and heavy metal quality of hydroponically grown produce needs to be paid attention.

Journal of Food Safety, EarlyView. Small-scale studies have shown that chlorine dioxide gas, ClO2(g), was effective for decontamination of produce, nuts, and spices. This study conducted a pilot-scale evaluation to identify effective ClO2(g) treatment parameters for commercial-scale applications.

Journal of Food Safety, EarlyView. COVID-19 has brought speculations on potential transmission routes of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of the pandemic. It is reported that the main route of virus transmission to be person-to-person by respiratory droplets; however, people have raised concerns on the possible transmission of SARS-CoV-2 to humans via food and packaging and its potential effects on food safety.

Journal of Food Safety, EarlyView. Food safety concerns associated with products purchased at farmers' markets have arisen, highlighting the growing need for farmers' market consumer and producer awareness of potential public health issues.

Journal of Food Safety, EarlyView. Campylobacter frequently contaminates chicken. Trisodium phosphate (TSP) is used for chicken decontamination; however, reduction of chemical preservatives is desirable. This study analyzed the efficacy of two commercial citrus-based products (CitroSan [CS] and Citrol-K Ultra [CK]) alone and in combination with TSP for reduction of Campylobacter in vitro and in chicken.

Journal of Food Safety, EarlyView. Culture-based Salmonella isolation consists of nonselective pre-enrichment, followed by selective enrichment in Rappaport–Vassiliadis (RV) or tetrathionate (TT) broths, and subsequent plating on selective indicator agar. This study aimed to assess the recovery of two strains belonging to serovars Montevideo (strain ATCC-8387) and Typhimurium (strain ATCC-14028) when grown together in different media.

Journal of Food Safety, EarlyView. Staphylococcus aureus is an important food pathogen that has the ability to form biofilms. This pathogen has been implicated in foodborne outbreaks associated with the consumption of meat and meat products. Since the role of meat products as reservoirs of antimicrobial resistant S. aureus and biofilm formers has not been studied, this research was conducted to assess the incidence, antimicrobial resistance, and presence of biofilm-forming genes in S.
