The paper presents an analysis of a technological process in a selected feed manufacturing plant, regarding the probability of transmitting feed additives among the manufactured feed mixtures and the risk of crosscontamination. Threats resulting from the use of coccidiostatics were determined at particular manufacturing stages. A technological model of the plant was made, identifying potential routes of cross-contamination between individual production batches. The cross-contamination effect in manufacturing a feed mixture for poultry was examined, with the maximum acceptable narasin level amounting to 70 mg/kg. A mixture containing narasin was produced, and next three successive series of the feed without any coccidiostatics were mixed on the same technological line, the socalled “collecting mixtures”. No purifying procedures were performed between the successive batches added to the mixer. The contamination level obtained in the first “collecting mixture” amounted to an average of 12%. The coccidiostatic content in the second and third mixture was below the bottom level of the quantifying method, namely below 3%. The results of the study were evaluated in reference to professional opinions in that particular subject area and the latest legal regulations.
