In order to ensure food safety, it is necessary to consider all aspects of the agri-food chain, from the primary agricultural production, including animal feed production to consumer supply, since each of these links in the chain may affect the safety of final products. In the feed production, each unit operation can contribute to the quality and safety risk of feed products. This paper isfocused on the identification and monitoring of critical points in the technological process of feed production, which are usually not covered by the HACCP quality assurance systems. Results of homogeneity and carry over in the critical control points showed that about 25 % of tested feed mills have a problem with residues in the process, which could be potential risk for cross contamination. In the three feed mills level of carry-over was slightly above limits, which may result in the creation of conditions for contamination of the subsequent batch. Additionally, results of the monitoring of Salmonella spp., Escherichia coli, and Staphylococcus aureus presence on the surfaces in feed millsshowed that feed factory environment might also represent one of the potential sources of final product contamination. Results showed that 7% of samples were positive to Salmonella sp. and even 50% of samples were positive on other bacterial contaminants. Introducing adequate control system will contribute to the identification of microbiological contaminants at all stages of production chain (feed-animal-foodhuman chain), as well on their prevention, which will have a direct impact on food safety and animal and human health.
