Sažetak
Toxoplasmosis is a zoonosis caused by the protozoan Toxoplasma gondii and is one of the most common meat-borne parasitic diseases. Since pork is one of the major sources of T. gondii infection in humans, seropositivity may be a good indicator of the presence of parasitic cysts in meat. Although most serological tests are mainly performed with blood serum, antibody screening of meat juice has been proposed as an alternative method. The aim of this study was to determine the prevalence of T. gondii antibodies in wild boar and domestic pig populations in relation to their origin in order to estimate the risk of toxoplasmosis in humans. In 2020, frozen diaphragms of 92 domestic pigs and 92 wild boars were collected from Trichinella- negative samples at the Karlovac Veterinary Station. Pigs were grouped based on the origin data, farm size and biosecurity level obtained from an competent authority. Samples were thawed and obtained meat juice samples were tested for the presence of T. gondii antibodies using a commercially available ELISA test. T. gondii antibodies were detected in 35 meat juice samples (38.04%, n=92) from domestic pigs and in 51 meat juice samples (55.43%, n=92) from wild boars. As expected, the largest proportion of positive samples in the domestic pig population (71.43%, n=25) were from small farms with up to five owned pigs. Moreover, 88.57% of them (n=31) belonged to farms with low biosecurity level (category "1" or "2"). The results suggest a high prevalence of T. gondii antibodies in pigs raised at family farms and especially in wild boars from Karlovac County. Meat juice serology can be proposed for continuous risk categorization of pig farms and hunting areas in the framework of the new Meat Safety Assurance System. The safety of meat from high-risk farms/hunting areas should be improved by interventions such as biosecurity measures and thermal treatment of meat during processing.
