Enzymatic Synthesis of Modified Alternaria Mycotoxins Using a Whole-Cell Biotransformation System [PDF]

Toxins, 2020
Reference standards for Alternaria mycotoxins are rarely available, especially the modified mycotoxins alternariol-3-glucoside (AOH-3-G), alternariol-9-glucoside (AOH-9-G), and alternariol monomethylether-3-glucoside (AME-3-G).

Scientific Opinion on the risks for human and animal health related to the presence of modified forms of certain mycotoxins in food and feed

EFSA Journal, 2014
Following a request from the European Commission, the risks to human and animal health related to modified forms of the Fusarium toxins zearalenone, nivalenol, T‐2 and HT‐2 toxins and fumonisins were evaluated. Modified (often called “masked”) mycotoxins

Current challenges in the diagnosis of zearalenone toxicosis as illustrated by a field case of hyperestrogenism in suckling piglets

Porcine Health Management, 2018
Background The mycotoxin zearalenone (ZEN) causes functional and morphological alterations in reproductive organs of pigs. In the field, diagnosis of ZEN-induced disorders is often challenging, as relevant feed lots are no longer available, or feed ...

Prevalent Human Gut Bacteria Hydrolyse and Metabolise Important Food-Derived Mycotoxins and Masked Mycotoxins

Toxins, 2020
Mycotoxins are important food contaminants that commonly co-occur with modified mycotoxins such as mycotoxin-glucosides in contaminated cereal grains. These masked mycotoxins are less toxic, but their breakdown and release of unconjugated mycotoxins has ...

Occurrence and co-occurrence of mycotoxins and their modified forms in children food and risk assessment

Food Science and Human Wellness
Mycotoxins are the toxic metabolites produced by the fungi that grow in food crops; however, the modified mycotoxins are the undetectable metabolites during testing for the parent mycotoxin.
