An Overview of Natural Toxins in Food

In the 1990s, Bruce Ames published several works in which he showed how almost all the insecticide molecules present in our diets were of natural origin. These are molecules that plants produce to defend themselves from parasites and that are, therefore, real insecticides, whose toxicological analysis is, however, incomplete.

The synthesis of these molecules is inversely proportional to the presence of pathogens and, therefore, it is reasonable to believe that in the absence of treatments with synthetic insecticides, as happens in organic farming, these natural insecticides are more present, but to date, there is a lack of data that allow us to know if organic foods contain a greater quantity of these molecules.

The comparison of the toxicological risk between natural and synthetic insecticide molecules is also worthy of further study.

Nowadays, the concept of One Health is more and more widespread, but it is essentially limited to zoonoses or toxic infections of foods of animal origin. Little attention is paid to the presence of toxic molecules of plant origin or to bacterial contamination of fresh or processed plant foods.

The aim of this Special Issue is, therefore, to create a state of the art for the presence of natural toxic molecules present in plant foods, fresh or subjected to technological treatments, and to evaluate their real danger for human health.

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 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 2700 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.
