Abstract:
Corn is one of the most produced cereals in the world for human and animal
consumption and the objective of this study was to analyze the conventional corn
cultivars P4285, P3898, AG1633 and B2828 in relation to contamination by
mycotoxins (aflatoxin, fumonisin, zearalenone and deoxynivalenol ) which are
harmful to humans and animals. These contaminations were observed through
mycotoxin analysis carried out in a laboratory. Among the mycotoxins, fumonisin (F.
culmorum, F. graminearum, F. crookwellense, and F. moniliformeo) had the highest
incidence in the four corn varieties, as the P4285 variety had a contamination of
2,850 pbb of fumonisin. Although zearalenone is produced from the same fungus as
fumonisin (Fusarium), it has not shown considerable data. Therefore, it is possible to observe that conventional corn cultivars are more susceptible to contamination by
fumonisin than by other mycotoxins in this study.
