On the basis of the performed analyses of the factors that contributed the infected meat reach food chain, we have found out that the infection occurred after consuming the meat inspected by the method of collective samples artificial digestion by using a magnetic stirrer (MM). In this work there are presented assay results which show how modifications of the method, on the level of final sedimentation, influence the reliability of Trichinella larvas detection in the infected meat samples. It has been shown that use of inadequate laboratory containers for larva collecting in final sedimentation and change of volume of digestive liquid that outflow during colouring preparations, can significantly influence inspection results. Larva detection errors ranged from 4 to 80% in presented the experimental groups in regard to the control group of samples inspected by using MM method, which had been carried out completely according to Europe Commission procedure No 2075/2005, where no errors in larva number per sample was found. We consider that the results of this work will contribute to the improvement of control of the method performance and especially of the critical point during inspection of meat samples to Trichinella larvas in Serbia.

The aim and task of this study was to determine the presence of ochratoxin A (OTA) residue in blood of swine, slaughtered regularly. The fact that ochratoxin A is heterogeneously distributed in a contaminated lot of feed material, makes the sampling problematic. It has been shown that an alternative method to monitor the presence of ochratoxin A in the feed is to analyze blood samples from swine, which reflect the toxin content of the ingested feed. With the aim of determining the presence of ochratoxin A residue in blood of swine slaughtered regularly, and originating from different areas of Vojvodina and Serbia, the samples were collected from the corresponding slaughter. During a three month investigation period, a total of 60 blood samples were analyzed. Spectrofluorimetric method was applied for sample analysis. The presence of the OTA residue was found in 56,6% of the examined plasma samples. The average OTA concentration in plasma was 2.91 ± 4.91 ng/mL (0,0-33,3 ng/mL). The experiment showed that the average OTA concentration in plasma samples originating from different areas of Vojvodina and Serbia, was not significantly low (p > 0,05).
