We have studied the changes of the structural-mechanical properties (elasticity, structural strenght and plastic strength) of pork from animals which have been exposed to combined treatment with 1 Gy radiation and acute poisoning with 250 mg of the phosphororganic pesticide AGRIA 1050 per 1 kg live weight. Comparisons are made with the structur-mechanical properties of meat from healthy animals, and from animals radiated only with 1 Gy. Two muscles were studied: m. Longissimus dorsi and m. Quadriceps femoris. The studies included a period of 120 hours of cold storage of the meat at +4 degree C post mortem. Higher structural and plastic strengthswere found in the meat from the animals radiated with 1 Gy within the 6-120 hour period compared to the meat from helthy animals. Lower values for these two characteristics were observed in the meat from the swines exposed to combined treatment with 1 Gy and phosphororganic pesticide "AGRIA 1050".
