Determination of working accuracy of feed plant provides useful information about critical points in production process. This enables implementation of corrective measures towards minimizing of contamination risk which is especially important for single-line plants in order to prevent contamination of non-targeted feed with medications from previous batches. In this investigation, working accuracy of two feed plants was tested. By observing the results it was concluded that in the first plant corrections must be made in mixing process, because even the longest mixing time (10 min) didn’t provide homogeneous mixture. On the other hand, carry over level for the longest mixing time was very small. In the second plant, results for mixing homogeneity were good for all three mixing times, but level of carry over was extremely high in the first rinsing batch. It can be concluded that first plant is not capable of producing and maintaining homogeneous mixture with existing equipment and the first step would be reconstruction of the mixer. In the second plant reconstruction of conveying system and implementation of rinsing batches is absolutely necessary.
