The contamination of wheat (Triticum aestivum) grain and flour samples by moulds, mesophilic aerobic bacteria and spores of aerobic bacteria was estimated in this work. The counts of amylolytic bacteria and their spores have been also assessed. The data were compared with microbiological standards of International Association for Cereal Science and Technology (ICC). It was stated that in wheat samples total number of bacteria and moulds met the requirements of ICC but in most flour samples the contamination by these groups of microorganisms was higher than ICC recommended level. In the samples of both wheat and flour the spores of aerobic bacteria occurred numerously. The considerable part of spores (in average 30% and 50% respectively in wheat and floor) characterized amylolytic activity. An average participation of amylolytic bacteria in total count of mesophilic aerobic bacteria in wheat and flour samples was similar and had the level about 8%. In the studied samples of wheat grain and flour there was marked the presence of mold fungi in most of the case of Penicillum and Aspergillus genus.
