Special Issue Information

Dear Colleagues,

Beverages satisfy basic needs for humans, but if they become contaminated, microorganisms can proliferate and cause spoilage or food poisoning. Recently, repeated detection of microbes, including enterobacteriaceae, in classic beverages such as carbonated soft drinks dispensed from fountain machines in developed countries, are now a major concern. For traditional fermented and non-fermented beverages, the beneficial or detrimental roles of microorganisms that are present are still not well explored. Therefore, it is important that more studies be carried out on the microbial safety of beverages, especially during manufacturing, handling, and storage. This Special Issue welcomes articles on microorganisms present in all types of beverages, with a clear connection to food safety. It covers new applications, microbial surveys, risk assessment, detection and quantification of microbial metabolites or toxins present in beverages. Reports dealing only with prevalence, characterization or identification (16S or 26S sequencing) of microorganisms will only be considered if new scientific information is included.

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 papers will be 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. Beverages is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) is waived for well-prepared manuscripts submitted to this issue. 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.

Listeria monocytogenes is a gram-positive food-borne pathogen that causes listeriosis in humans. Currently, there is little information on the prevalence of Listeria monocytogenes in raw milk and traditional yoghurt-like milk beverage, nunu, in Ghana. The purpose of this study was to investigate the prevalence of L. monocytogenes isolates in raw cow milk, boiled milk and nunu in Ghana, and to characterize these L. monocytogenes isolates according to their serogroups, virulence potentials and antibiotic susceptibility profiles. A total of 254 samples comprising 114 raw cow milk, 56 boiled milk and 84 nunu were collected from dairy farms and market vendors for detection of L. monocytogenes. The overall prevalence of L. monocytogenes in raw milk, boiled milk and nunu was 5.5% (14/254). Listeria monocytogenes was prevalent in raw cow milk (8.8%; 10/114) and nunu (13.1%; 11/84), while no Listeria spp. was not detected in boiled milk. A total of 62 L. monocytogenes isolates were analysed to belong to molecular serogroups 1/2a-3a (32/62, 51.6%), 1/2b-3b-7 (14/62, 22.6%), 4b-4d-4e (9/62, 14.5%) and 1/2c-3c (7/62, 11.3%). All 62 L. monocytogenes isolates harbored the virulence-associated genes inlA, inlB, inlC, inlJ, plcA, actA, hlyA, iap and prfA. All Listeria monocytogenes in the present study were generally susceptible to the tested antibiotics, except neomycin and tetracycline, for which phenotypic resistance was observed among isolates.
