MICROBIOLOGICAL QUALITY OF FEED MATERIALS USED IN POLAND

ELŻBIETA KUKIER AND KRZYSZTOF KWIATEK

Microbiological quality of feed materials used in Poland in 2007-2010 was assessed. The examinations were conducted at all veterinary diagnostic laboratories. Feed samples were examined on Salmonella prevalence and level of contamination by aerobic mesophilic bacteria, microorganisms, Enterobacteriaceae and fungi. Salmonella sp. was the most often detected in feed materials of animal origin. The number of Enterobacteriaceae in most of the examined feed samples did not exceed 10 cfu/g. The demonstrated contamination by aerobic bacteria ranged most often from 10 to 10 7 cfu/g. Analysis of mycological status of feed materials indicated that the highest contamination by fungi was 10 8 cfu/g in cereal grains.

Key words: feeds, microbiological quality, bacteria, fungi, Poland.
