192Proceeding of the 4 rd International Symposium“NEW RESEARCH IN BIOTECHNOLOGY” USAMV Bucharest, Romania, 20113. RESULTS AND DISCUSSIONSThe microbiological analysis: total number of germ (NTG), yeasts and molds(YM), mycotoxin content (DON, ZEA) and percentage of impurities and foreign bodies andmoldy grains are presented in Table 1 for the wheat samples analyzed in all the 8 counties.For 33.3% of the samples analyzed, impurities and foreign bodies content exceedsthe maximum accepted percentage of 15% due to the percentage of kernels affected bypests (bug especially) and sprouted or fungal contamination.In the same county, Dropia variety had different mycotoxin values, varying frombelow the limit of detection to higher values. For example, in Teleorman county DONcontent varied from not detected values to 279.94 g/kg. Also, same situation in Dolj, Buzăuand Brăila. This can be due to the local environmental condition (soil conditions,meteorological conditions, harvesting agricultural technologies).Table 1.
