Toxicological effects of fumonisin B 1 in combination with other Fusarium toxins.

Fusarium is a fungal genus spread worldwide commonly associated to the production of several mycotoxins, where fumonisins (FBs) are of major importance due to its prevalence. Since mycotoxins have been reported to cause deleterious effects on mammalians, including carcinogenic, neurotoxic, estrogenic, and immune-suppressive, many countries had established regulations on the tolerated concentrations of such substances in foods and animal feed. Even though many mycotoxins - especially fusariotoxins - are concomitantly found in a single matrix, there is no regulation on co-occurrence levels. This is possibly a result of the lack of data in the literature on the toxicological interactions between different mycotoxins. Considering this, it is of utmost importance to gather what is currently known about the combination of FBs, considered to be the most ubiquitous mycotoxins, with other frequently reported fusariotoxins, such as zearalenone (ZEA), deoxynivalenol (DON), nivalenol (NIV), T-2 toxin (T-2), and other emerging mycotoxins. This paper gives an overview about the toxic effects of fusariotoxins individually and combined to FB ₁ , also gathering the mechanisms and probable interactions between them. This important information may help to develop regulations covering multi-mycotoxins contamination, a growing concern of current days.
