Abstract:
Contamination by molds is a severe problem in fields
as well as storage conditions causing significant loss in yield and quality
of several commodities. Many of these molds produce mycotoxins, which
are toxic to animals and are responsible for many acute and chronic human
diseases. Rice, an important food commodity is susceptible to fungal infection
in field as well as storage, hence, rice samples grown under different
agro-climatic conditions were screened for molds and toxins produced by
Fusarium sp., an important toxigenic storage fungi. High incidence
of storage molds in all the samples was observed. Twenty two different
species belonging to 16 genera were recorded. Aspergillus flavus,
Fusarium moniliforme and Penicillium sp. were the predominant
ones. Among the 64 Fusarium isolates, 17 were found to be toxigenic.
High performance thin layer chromatography and HPLC analyses of commodities
revealed the presence of Fusarium toxins deoxynivalenol, nivalenol,
diacetoxyscirpenol, T-2, HT-2 and zearalenone. Among these toxins, deoxynivalenol
and zearalenone were found in high levels ranging from 20 to 500 μg
kg-1, with samples from Western Ghats showing the maximum level
of 500 μg kg-1.
