Special Issue Information

Dear Colleagues,

Foodborne pathogens (e.g., viruses, bacteria, parasites) are responsible for millions of illnesses and thousands of deaths worldwide, with significant effects on human health and economy. Foodborne illness occurs when a pathogen is ingested with food, or when a toxigenic pathogen produces a toxin, ingested by the human host. A high level of protection of public health is one of the fundamental objectives of food law, according to which food must not be placed on the market if unsafe. Several technologies and antimicrobials are applied to control the presence of pathogens in food. Food safety can be ensured by a preventive approach, such as the implementation of good hygiene practices and or the use of innovative packaging. Both natural and chemical antimicrobial agents can be used as food preservatives. Natural antimicrobials are currently growing for their ability to inhibit pathogens without negative safety concerns. Further, bacteria, fungi, parasites, and viruses have developed numerous resistance mechanisms against current antibiotics. Hence, there is an imperative demand for innovative molecules and applications to address multidrug resistance. This Special Issue is dedicated to all the applications that target to control of the presence of pathogens in Food Production, to all the studies that evaluate food production chains that require particular attention for microbial contamination control, or that analyze compounds, nanoparticles, technologies used to obtain microbiological fight in the agri-food chain, in order to guarantee the safety of final products and consumers protection.

Manuscript Submission Information

Manuscripts should be submitted online at mdpi.longhoe.net 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. Antibiotics is an international peer-reviewed open access monthly 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.

In ready-to-eat products, such as cooked ham, fresh cheese, and fuet in which Listeria monocytogenes is a concern, the use of biopreservation techniques represents an additional hurdle to inhibit pathogen growth during storage. The objective of this study was to apply several biopreservation techniques in three different food matrices to reduce the growth of Listeria innocua, used as a surrogate of L. monocytogenes. Several lactic acid bacteria, the bacteriocin nisin, the bacteriophage PhageGuard ListexTM P100, and the enzyme lysozyme were evaluated. Cooked ham treated with the bacteriophage PhageGuard ListexTM at 0.5% or with the lactic acid bacteria SafePro® B-SF-43 (25 g/100 kg) reduced L. innocua population to below the detection limit after 7 days of storage (4 °C plus modified atmosphere packaging). In fresh cheese, the application of PhageGuard ListexTM at 0.2 and 0.5% reduced L. innocua counts by more than 3.4 logarithmic units after 6 days at 4 °C. In fuet, the 1.0% of PhageGuard ListexTM reduced L. innocua population by 0.7 ± 0.2 logarithmic units in front of control with no significant differences to other evaluated biopreservative agents. The present results confirm that the application of biopreservation techniques was able to inhibit L. innocua in fuet, cooked ham, and fresh cheese, and suggest that the type of food matrix and its physicochemical characteristics influence the biopreservative efficacy.
