Investigation on the Occurrence of Ochratoxin A in Maize in Bangladesh

Abstract

Maize was collected from different markets of Bangladesh for the determination of ochratoxin A. Simultaneously controlled maize samples were analyzed to assess the ochratoxin A level of market samples and that of controlled samples. A total of 120 samples were analyzed to determine ochratoxin A including 70 market samples and 50 controlled samples. Market samples were found containing a high contamination level of ochratoxin A ranged from 1 to 117 μg/kg and incidence rate was 40% whereas in the controlled samples the contamination rate was found very low ranged from 3 to 9 μg/kg and the incidence rate was found 10% only.
