Special Issue Information
Dear Colleagues,
Climate change is likely to give origin to new or re-emerging hazards in marine ecosystems, consequently affecting the safety of seafood. Global warming as well as ocean acidification and increased deoxygenation damage both marine life and biodiversity. They can cause expanding species to move and change their distribution ranges, leading to shifts in food webs and ecosystem dynamics. They also have an impact on eutrophication by favoring the appearance and intensity of harmful algal blooms, which can produce marine biotoxins, some of which are unknown. Among these emerging marine biotoxins, cyclic imines, which include the lipophilic compounds spirolides, gymnodimines, and pinnatoxins, may imply harmful effects on human health. The development and validation of novel or confirmatory analytical methods, such as Orbitrap, mass spectrometry, chromatography, and nanotechnology, are particularly expected to detect unknown marine biotoxins instead of applying a mouse bioassay, which represents the reference method in such cases. Current predictions show that the warming of marine waters due to global climatic change may increase the transmission of microbial agents, such as non-cholera Vibrio spp., which are autochthonous to the aquatic environment. Some species, such as Vibrio parahaemolyticus and Vibrio vulnificus, are indicated among the biological hazards with a very high likelihood of emerging worldwide. Climate change-driven alterations to marine biogeochemistry may also impact the formation and trophic transfer of the bioaccumulated neurotoxin methylmercury. The connections between physical changes and the environmental fate of this compound are combined by examining the effects on transport and biogeochemical transformations. This Special Issue aims to publish original research and review articles related to the impact of climate change on biological and chemical hazards in marine ecosystems, monitoring and potential mitigation, and urgent solutions.

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.
