In the territory of Serbia, the occurrence of trichinellosis in domestic pigs has been present for a long number of years. In a ten-year period, a total of 1,224 pigs were registered in one populated area with the diagnosis of a larval form of the parasite Trichinella spiralis. In the middle of the period of examination, a systematic deratization of the complete settlement was carried out, the neighboring garbage dumps, and a pit grave. The systematic deratization was performed using the preparation Brodisan. The analysis of the trend in the number of infected pigs after the systematic deratization was performed in the examined area, it was established on the grounds of the negative parameter b of the straight line trend, that the average annual reduction in the number of infected pigs was 39.80. The tendency of a reduction of the number of infected pigs following the systematic deratization is best described by a second degree polynomial because its correlation coefficient is Rxy=0.98.
