Abstract

Rice samples including paddy, husk, brown rice, blue-tinged rice, broken rice, discolored rice and polished rice were collected from rice processing complexes(RPC) nationwide to determine the contamination of fungi and mycotoxins on rice during 2010-2013. Among the samples, paddy rice had the highest frequencies of fungal and Fusarium occurrence, and the frequencies decreased along with milling as husk was the next. Blue-tinged rice or discolored rice was similar with brown rice for fungal occurrence, and polished rice showed the lowest frequency. Among Fusarium species, F. graminearum species complex occupied 87% in 2012 but did 35-39% in 2011 and 2013. Aspergillus and Penicillium species appeared at low frequency in most samples but occurred at higher frequency in certain RPC samples. Alternaria, Nigrospora, and Epicoccum species occurred similarly to the pattern of total fungi. The rice samples from 2010-2012 were analyzed for the occurrence of Fusarium mycotoxins including deoxynivalenol, nivalenol, zearalenone, and other trichothecenes. The most highly contaminated sample was discolored rice in terms of frequency, level, ratio of simultaneous contamination with multiple toxins, followed by blue-tinged rice.

Key Words: Fungi, Fusarium, Mycotoxin, Rice, Rice processing complex
