Mycotoxins are toxic secondary metabolites generated from toxigenic fungi in the contaminated food and agro-food, which have been regarded as a serious threat to the food safety and human health. Therefore, the control of mycotoxins and toxigenic fungi contamination is of great significance and has attracted the increasing attention of researchers. As we know, nano-semiconductors have many unique properties such as large surface area, structural stability, good biocompatibility, excellent photoelectrical properties, and low cost, which have been developed and applied in many research fields. Recently, nano-semiconductors have also been promisingly applied in mitigating or controlling mycotoxins and toxigenic fungi contaminations in food and agro-food. In this review, the type, occurrence, and toxicity of main mycotoxins in food and agro-food were introduced. Then, a variety of strategies to mitigate the mycotoxin contamination based on nano-semiconductors involving mycotoxins detection, inhibition of toxigenic fungi, and mycotoxins degradation were summarized. Finally, the outlook, opportunities, and challenges have prospected in the future for the mitigation of mycotoxins and toxigenic fungi based on nano-semiconductors.

Enterohemorrhagic (EHEC), a pathotype within the Shiga toxin-producing (STEC) group, is a major etiological agent of severe gastrointestinal illness and life-threatening sequelae, including hemolytic uremic syndrome. Although insights into EHEC pathogenesis have been gained through traditional 2D cell culture systems and animal models, these platforms are limited in their ability to recapitulate human-specific physiological responses and tissue-level interactions. Recent progress in three-dimensional (3D) cell culture systems, such as spheroids, organoids, and organ-on-a-chip (OoC) technologies, has enabled more physiologically relevant models for investigating host-pathogen dynamics.

Cold stress during forward processing delays of lettuce can induce the formation of viable but nonculturable (VBNC) cells of Shiga toxin-producing Escherichia coli (STEC) O157:H7 and pose risks of foodborne disease outbreaks. This study investigated the effect of physiological changes during the forward processing cold chain on the risks of illness from consuming lettuce contaminated with STEC O157:H7. A probabilistic quantitative microbial risk assessment model was developed to quantify the risks associated with consuming field-bagged Romaine hearts and shredded and packaged lettuce contaminated with STEC O157:H7.

Background: is an emerging zoonotic pathogen capable of cau-sing diphtheria-like infections in humans.
Objectives: we report, for the first time in Brazil, the detection and phenotypic/genomic characterization of three atoxigenic ST-339 strains isolated from domestic animals, including one with a ciprofloxacin resistance profile linked to double GyrA mutations (S89L, D93G).
Methods: species identification was performed by MALDI-TOF MS, followed by in vitro antimicrobial susceptibility testing, whole-genome sequencing, and bioinformatic analyses to predict virulence determinants, antimicrobial resistance genes, CRISPR-Cas systems, mobile genetic elements, and in silico structural analysis as well as phylogenetic reconstruction.

Mycotoxins are secondary metabolites produced primarily by certain species of the genera , , , , and . Toxigenic fungi and mycotoxins are prevalent in staple foods, resulting in significant economic losses and detrimental impacts on public health and food safety. These fungi demonstrate remarkable adaptation to water and heat stress conditions associated with climate change, and the use of synthetic antifungals can lead to the selection of resistant strains.
