Zearalenone is a mycotoxin produced by various species of Fusarium fungi, with occurrence in corn, barley, wheat, and oat. Several countries, including Brazil, have specific regulations referring cereal concentrations, because doses above 1ppm on the diet may cause hyperestrogenism. The present study was carried out to evaluate the main raw materials used in swine feed, between 2017 and 2020. It were considered corn, sorghum, soy and rice samples, and the results were correlated with the appearance of clinical signs. Zearalenone may cause decrease in feed consumption, estrogenic syndrome, where it occurs vulva enlargement, heat repetition, anestrus and even so abortion, but also may not cause any apparent sign, depending on the amount present in the diet. 2943 samples were evaluated, belonging to a commercial laboratory Mercolab, and the results shows us a low prevalence regarding the minimum level of 1ppm, considered by literature as minimum value to the appearance of signs. During winter, we could see a contamination increase, and during the summer, we had the lowest minimum average in relation to the other seasons. Among the samples that were used, rice presented the biggest contamination increase.
