Regarding the occurrence of Ochratoxin A, during winter season, out of 40 local and imported corn grains, 2 positive samples for Ochratoxin A (5%). In summer, 3 positive samples for Ochratoxin A, (7.5%) in local and imported corn. The occurrence of Zearalenone, in winter season, 2 positive samples out of 40 local and imported corns with (5%).
