SYSTEM OF THE RESIDUE INVESTIGATION OF FO ODSTUFFS OF ANIMAL ORIGIN, ITS RESULTS AND TRENDS OF THE DEVELOPMENT IN HUNGARY - SHORT ACCOUNT

Performance and evaluation of die monitoring investigation of chemical residues (xenobiotics), harmful for the health, according to Hungaria n and international regulations - complementing the food-hygienic meat inspection - are duties of the veterinary food safety service. Beside s the screening of the antibacterial effect with the so-called 4-6 dis hes microbiological method, instrumental analytical methods of high se nsitivity serve for their control (GC, HPLC, HPTLC, GC-MS, GC-FTIR, RI A, ELISA, AAS, AAS-ETA etc). In positive cases, the confirmation of be fore mentioned matters belonging to the drug residue group (microbiolo gically active substances) is carried out also instrumental analytical methods. The monitoring control also comprises the high performance, confirmatory demonstration of chlorinated hydrocarbons, poly-chlorinat ed biphenyls (PCB), organophosphorus compounds, synthetic pyrethroids and other agrochemicals, toxic and micro elements, thyroid antagonists , mycotoxins, anabolic hormones and drugs with hormonic activity, tran quillizers, beta-receptor blocking agents (agonizers), antiparasitics and nitrosamines. Results of the investigations - accepted also by the US and EEC food safety authorities - have documented that the mean re sidue contamination of Hungarian foodstuffs of animal origin is much l ower than the maximal tolerance level (MRL) determined for the individ ual drugs. By this investigation system, the possible negative tendenc ies can also be detected.
