Nitrite is a common additive used during meat curing to prevent microbial contamination and retain an attractive red color in the product. However, the effects of nitrite on Fenton reactions catalyzed by free iron in meat products are not well understood, although such processes can induce protein oxidation and nitration, affecting the nutritional and aesthetic quality of meat products.

In recent years, the use of bacteriocin-producing Lactobacillus species has received much attention in different areas, including using as probiotics, food preservation, and as broad antimicrobial spectrum activity. In this study, a bacteriocin-producing Lactobacillus strain was isolated from traditional yogurt. The isolate was identified by morphological, biochemical, 16S rRNA analyses, and designated as Latilactobacillus curvatus LAB-3H.

To solve the heavy metal water contamination problem of mercury ions, salix psammophila (SPP) powder was functionalized by thiol to prepare a novel adsorbent (TSPP). The materials were characterized by scanning electron microscope (SEM), Fourier-transform infrared (FTIR), energy-dispersive spectroscopy (EDS), thermogravimetry (TG), and X-ray photoelectron spectroscopy (XPS).

Journal of Food Safety, EarlyView. An edible polysaccharide film with high tensile strength and biodegradability was prepared by freeze–thaw treatment with sodium alginate (SA) and hyaluronic acid (HA) and cross-linking with calcium lactate. The SA/HA ratio, the calcium concentration, the number of freeze–thaw cycles, and the calcification time all have significant effects on the tensile strength of SA/HA films.

Many bacterial pathogens employ a protein complex, termed the type III secretion system (T3SS), to inject bacterial effectors into host cells. These effectors manipulate various cellular processes to promote bacterial growth and survival. The T3SS complex adopts a nano-syringe shape that is assembled across the bacterial membranes, with an extracellular needle extending toward the host cell membrane.

The cfr and lsa(E) genes both cause multiple drug resistance and have been identified in numerous Staphylococcus species, respectively.

In vitro experimental evolution of pathogens to antibiotics is commonly used for the identification of clinical biomarkers associated with antibiotic resistance. Microdroplet emulsions allow exquisite control of spatial structure, species complexity, and selection microenvironments for such studies. We investigated the use of monodisperse microdroplets in experimental evolution.

Journal of Food Safety, EarlyView. Salmonella spp. and Escherichia coli are well tolerant of freezing.

Journal of Food Safety, EarlyView. Healthy colonized cattle are the major reservoir of Shiga toxin–producing Escherichia coli (STEC) and play a key role in the entry point of the pathogen into the beef chain. Excretion rates and the concentration of the pathogen in feces influence the epidemiology and transmission of the pathogen within herds and to humans. This study evaluated the prevalence and dynamics of fecal shedding of STEC by cattle in a commercial feedlot in Gauteng, South Africa.

Humans are exposed to a broad range of organic chemicals. Although targeted gas chromatography mass spectrometry techniques are used to quantify a limited number of persistent organic pollutants and trace organic contaminants in biological samples, nontargeted, high-resolution mass spectrometry (HRMS) methods assess the human exposome more extensively.

Occupational exposures to volatile organic compounds (VOCs) have been associated with numerous health complications including steatohepatitis and liver cancer. However, the potential impact of environmental/residential VOC exposures on liver health and function is largely unknown. To address this knowledge gap, the objective of this cross-sectional study is to investigate associations between VOCs and liver injury biomarkers in community residents.

Neurotoxicity is a principal concern in nonclinical drug development. However, standardized and universally accepted fluid biomarkers for evaluating neurotoxicity are lacking.
