Journal of Food Science, EarlyView. To estimate human exposure to Salmonella enterica, it is essential to understand the pathogen distribution and characteristics. Prevalence and concentration of S. enterica were determined in mango, tomato, and raw chicken samples purchased in three states (Aguascalientes, Querétaro, and Guadalajara) located in the central region of Mexico during two seasons. In addition, S.

Journal of Food Science, EarlyView. Medicine food homologous (MFH) plants provide therapeutic and health care effects through diet. Thus, a risk assessment system for hazardous ingredient residues is urgently required to ensure their safe use.

Journal of Food Science, EarlyView. Real-time and sensitive detection of pathogenic bacteria in food is in high demand to ensure food safety. In this study, a single-walled carbon nanotubes (SWCNTs)-based electrochemical impedance immunosensor for on-site detection of Listeria monocytogenes (L. monocytogenes) was developed. A gold-plated wire was functionalized using polyethylenimine (PEI), SWCNTs, streptavidin, biotinylated L. monocytogenes antibodies, and bovine serum albumin (BSA).

Journal of Food Science, EarlyView. The antibacterial and antifungal effects of six plant-derived essential oils (EOs) and two types of citrus extracts (CEs) were studied against two pathogenic bacteria (Salmonella Typhimurium and Escherichia coli O157:H7) and three fungi (Aspergillus niger, Penicillium chrysogenum, and Mucor circinelloides).

Journal of Food Science, EarlyView. Detoxification of aflatoxin M1 from solution and milk using layered double hydroxides was investigated. The Aluminum-Magnesium layered double hydroxide (Al-Mg LDH) and Iron-Magnesium layered double hydroxide (Fe-Mg LDH) were selected in their calcined and non-calcined forms to evaluate the effect of the calcination on detoxification. These materials were produced using the co-precipitation method.

Journal of Food Science, EarlyView. Under the Food Safety Modernization Act (FSMA) and preventive controls (PCs) regulations, food manufacturers must consider whether PCs are needed for potential hazards present in food. The mycotoxin ochratoxin A (OTA) is considered a chemical hazard under FSMA. It is produced by several fungal species and can be present in various agricultural commodities, including coffee.

Dietary intake of polychlorinated dioxins and furans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) from various foods (fish and seafood, meat and meat-based products, milk and dairy products, hen eggs, olive oil and fats) was investigated for various sex/age groups of the Italian population. The concentrations of PCDD/Fs and dl-PCBs and their contribution to total TEQ values varied depending on food matrix.

Journal of Food Science, EarlyView. To evaluate the pollution level of toxic elements in edible mushrooms from Jilin Province, China, the lead, cadmium, mercury, and arsenic content present in them were monitored and evaluated. A total of 610 edible mushroom samples, including fresh and dried, were collected from nine cities in the Jilin Province.

Journal of Food Science, EarlyView. The environment in poultry abattoirs is the primary potential source of bacterial contamination and cross-contamination of broiler carcasses. In this context, we explored the influence of chilling water and contact surfaces on the microbial diversity of broiler carcasses in warm and cold seasons. High-throughput sequencing was used to target the V3-V4 region of the 16S rRNA gene.

Journal of Food Science, EarlyView. Since microplastics (MPs) bring the potential risks to human health when plastics are ingested, more needs to be known about the presence and abundance of human ingestion of MPs. To address these issues, we reviewed 108 publications in Web of Science concerning abundances, sources, and analytical methods of MPs in human daily intake including fish, salt, drinking water, beverages, package food, and other food.

Journal of Food Science, EarlyView. This study was designed to investigate the prevalence and associated risk factors of Shigella flexneri isolated from drinking water and retail raw food samples in Peshawar, Pakistan. A total of 1,020 different samples were collected from various areas of Peshawar between January 2016 and May 2017, followed by identification of S. flexneri through biochemical, serological, and 16S rRNA gene sequencing.

Journal of Food Science, EarlyView. Heat-resistant foodborne pathogens have been a concern in low-moisture foods and ingredients (LMFs). Due to low thermal conductivity of low moisture materials, thermal treatment is not efficient and may cause nutritional loss. This study investigated the enhancement of thermal treatment of meat and bone meal (MBM) at low water activity (aw) by inclusion of butylparaben (BP) as a model antimicrobial compound.

Journal of Food Science, EarlyView. Salmonella, being one of the most widespread foodborne pathogens, is a compulsory test item required by national food safety standard of China and many other countries. More sensitive and specific Salmonella detection method is still needed since traditional methods are time consuming and highly dependent on enormous manpower and material resources.

Journal of Food Science, EarlyView. In this work, the occurrence of 34 common antibiotic (15 sulfonamides and 19 quinolones) residues were evaluated in 236 ready‐to‐eat duck eggs (salted and preserved duck eggs) marketed through e‐commerce stores by ultra‐performance liquid chromatography coupled to tandem mass spectrometry, and subsequent dietary risk assessments for Chinese consumers were conducted.

Journal of Food Science, EarlyView. The aim of the present study was to design a delivery system of curcumin (CU) loaded solid lipid nanoparticles (CU‐CSLNs) for evaluating the antimicrobial properties in hamburger patty. Solid lipid nanoparticle (SLN) was prepared through a homogenizing technique.

Journal of Food Science, EarlyView. Acrylamide (AA), which is a carcinogen in humans, has been a research focus in terms of food risk assessment. However, few published studies have explored protein strategies to reduce the health risks of AA. The objective of this study was to investigate the binding of AA with soy protein isolate (SPI) and elucidate the binding mechanism.

Journal of Food Science, EarlyView. Wheat (Triticum aestivum) is susceptible to mycotoxin contamination, which can result in significant health risks and economic losses. This research examined the ability of air atmospheric cold plasma (air‐ACP) treatment to reduce pure and spiked T‐2 and HT‐2 mycotoxins’ concentration on wheat grains. This study also evaluated the effect of ACP treatment using different gases on wheat grain germination parameters.

Seafood is capable of bioaccumulating heavy metals (HM), making it a potentially major dietary source of HM for humans. Presently, little data exists on seafood from the eastern‐most boundary of the Mediterranean Sea. This study aims to provide exposure insight of the Israeli population to HM through the consumption of locally caught seafood by assessing the levels of arsenic, mercury, cadmium, and lead in raw tissues of seafood.

Consumption of nutrient‐rich seaweeds and fermented nondairy foods represent fast growing trends among health‐minded consumers. Assessment of lacto‐fermented seaweed was performed to address these trends, and to offer shelf‐life extension and product diversification for fresh kelps.

This review considers how research in China has progressed our understanding and subsequent improved control of Cronobacter. This emergent bacterial pathogen is associated with neonatal infections through the ingestion of contaminated prepared feed. The review includes large‐scale surveys of various sources of the organism, including infant formula production facilities. The analysis of over 20,000 samples is presented.

The objective of this survey was to estimate the prevalence, contamination level, and genetic diversity of Salmonella in selected raw, shelled tree nuts (Brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pine nuts, pistachios, and walnuts) at retail markets in the United States. A total of 3,374 samples of eight tree nuts were collected from different types of retail stores and markets nationwide between September 2015 and March 2017.
