Sažetak
Microbiological safety of poultry feed is an essential prerequisite for poultry health and production. Presence of bacteria such as Salmonella, Clostridium, Staphylococcus and E. coli, as well as moulds in feed can indirectly become a problem in public health. This is due to ability of bacteria and moulds to survive in different environmental conditions using various possibilities of spread, their pathogeny and toxicity. In poultry production, microbiologically contaminated feed can in addition to its effects on animal health cause significant production losses. In our research, we microbiologically examined the samples of corn, feed, meat and bone meal. We detected 4,5% of samples microbiologically unsafe due to the presence of Salmonella and Clostridium species. The total bacteria counts exceeded the limits permitted by legislation in 2.5% of examined samples, while 5.5% of samples were unsafe due to the exceeded limit of yeasts and moulds (most frequently: Fusarium and Mucor species). In spite of a relatively small number of samples, our results indicated the incidence of microbiologically contaminated feed and the need for continuous control of feed samples.
