Emerging mycotoxins induce hepatotoxicity in pigs' precision-cut liver slices and HepG2 cells.

Emerging mycotoxins are currently gaining more attention due to their high frequency of contamination in foods and grains. However, most data available in the literature are in vitro, with few in vivo results that prevent establishing their regulation. Beauvericin (BEA), enniatins (ENNs), emodin (EMO), apicidin (API) and aurofusarin (AFN) are emerging mycotoxins frequently found contaminating food and there is growing interest in studying their impact on the liver, a key organ in the metabolization of these components.

Deoxynivalenol induces apoptosis and inflammation in the liver: Analysis using precision-cut liver slices.

Deoxynivalenol (DON) is one of the most common mycotoxins in cereals and their by-products. Its adverse effects on animal and human health have been extensively studied in the intestine, but little attention has been paid to another target organ for mycotoxins, the liver that is potentially exposed after intestinal absorption and enterohepatic circulation. To assess DON's toxicity in an ex vivo model structurally and physiologically closer to the whole liver, we developed a pig precision-cut liver slices (PCLS) model.

Co-occurrence of DON and Emerging Mycotoxins in Worldwide Finished Pig Feed and Their Combined Toxicity in Intestinal Cells.

Food and feed can be naturally contaminated by several mycotoxins, and concern about the hazard of exposure to mycotoxin mixtures is increasing. In this study, more than 800 metabolites were analyzed in 524 finished pig feed samples collected worldwide. Eighty-eight percent of the samples were co-contaminated with deoxynivalenol (DON) and other regulated/emerging mycotoxins.
