Abstract

Zearalenone (ZEN) is a mycotoxin produced by Fusarium fungi that contaminates food and feed, affecting both human and animal health. Among farm animals, the pig is a great consumer of grains and has a native sensitivity to mycotoxins. As the main route of contamination is oral, the intestine is the first defense barrier that plays an important role in the immune response being able to secrete effector molecules (cytokines). At the European level, there are no regulations regarding the amount of ZEN that can be present in the feed of piglets, only recommendations for piglets 0.100 mg ZEN/kg feed (100 ppb). In this study, the effects of ZEN in concentrations below (75 ppb) and above (290 ppb) EU recommendation on the level of some key markers involved in the oxidative and inflammatory response, as well as the mechanisms and signaling pathways through which ZEN could produce its toxicity, were monitored in the colon of weaned piglets. The exposure of the piglets to the lower concentration of ZEN (75 ppb) did not lead to changes in stress and inflammation markers or in the signaling pathways associated with these processes.
