Special Issue "Mycotoxins in Feed: Harm to Animals"
Deadline for manuscript submissions: closed (1 August 2020).
Mycotoxins in feed constitute a great health risk to farmed animals, and may also involve human health concerns via the consumption of animal products. The mycotoxins in feed originate from moulds that infest and develop in the feed plants under field growth, or in the feed or feed materials after improper storage. Fusarium species are considered the most important mycotoxin-producing field fungi, whereas species within the genera Penicillium and Aspergillus are mycotoxin producers during storage. Data on the occurrence of mycotoxins in animal feed are important regarding the evaluation of risks, but are restricted.
Health disorders in animals are only known for a rather low number of mycotoxins. Fusarium mycotoxins in animal feed, such as DON and some other trichothecenes, are known to elicit gastrointestinal disorders and immune suppression, whereas zearalenone creates oestrogenic disturbances, and fumonisins manifest different disorders in animal species. The intake of ochratoxin, which is produced by Penicillium and Aspergillus moulds, may damage the kidneys particularly of pigs, and aflatoxins, produced by Aspergilli, are carcinogenic and toxic to the liver. Furthermore, ergot alkaloids, produced by Claviceps purpurea in the field, are neurotoxic and inhibit blood circulation. The dose–effect relations of these toxins in various animal species are of great value in risk assessments, but are scarcely known.
Beyond the most studied ones, the number of other mycotoxins and metabolites of potential, but largely unknown risk in animals, is formidable, and also, knowledge of combined exposure to mycotoxins in highly needed.
We look forward to receiving your contributions for this Special Issue, in the form of original research, case studies, or review papers, shedding light on perspectives on occurrence of various mycotoxins in feed, and their implications for disease developments in animals under realistic conditions.

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 double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins 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 2000 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.
