Special Issue Information

Dear Colleagues,

Foodborne pathogens are a major cause of illness and death worldwide. Diseases caused by these pathogens can range from mild gastroenteritis to severe, life-threatening conditions. Reducing pathogens in the food supply directly decreases the incidence of foodborne illnesses, improving public health outcomes. Ensuring that food products are free from harmful pathogens enhances their safety and quality. This leads to greater consumer confidence and trust in the food supply, promoting better dietary choices and overall health. Thus, proper strategies are critical to effectively reduce foodborne pathogens, ensuring the safety and quality of food supply from farm to table. In this Special Issue, we invite you to submit comprehensive reviews, research articles and short communications on the positive effects of identifying and implementing strategies to minimize the presence and impact of harmful microorganisms in the food industry, including improved detection methods, pre-harvest interventions, food packaging innovations and new antimicrobial natural agents.

Dr. Kai Zhong
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Foods is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Bacillus cereus sensu lato (B. cereus s.l.) are significant spoilage and pathogenic microorganisms found in various foodstuffs. They are responsible for defects like sweet curdling in milk, which impacts dairy product storage and distribution. Nevertheless, the genetic mechanisms underlying B. cereus-induced sweet curdling remain poorly characterized. In this study, we investigated the genetic and functional basis underlying this phenomenon through whole genome sequencing of the newly isolated B. cereus strain BC46 and transcriptome sequencing at two phases of its growth in milk. Hybrid assembly of Illumina and Nanopore reads resulted in a 5.6 Mb genome with 35.1% GC content, classifying BC46 as B. cereus sensu stricto (B. cereus s.s.) within the panC group IV. Several virulence factors, antimicrobial resistance genes, and cold shock proteins were identified in the genome. A distinct functional profile of BC46 was observed before and after the development of sweet curdling in milk. Genes associated with sporulation, toxin production, hydrolysis, and proteolysis were upregulated in sweet-curdled samples. Our findings highlight potential gene targets that may play an important role in the BC46-induced sweet curdling in milk, enhancing our understanding of its molecular basis and supporting the development of new genetic approaches for early spoilage detection.
