| Sumario: | <i>Trichinella</i> nematodes continue to circulate in various hosts both in the domestic and sylvatic cycles. In the majority of countries in Europe, wild boars have been noticed as a primary source of <i>Trichinella</i> spp. infections in humans. However, in some regions, the meat of pigs containing <i>Trichinella</i> spp. larvae can still be a cause of trichinellosis. Therefore, in the present study, we aimed to determine and present actual data on the occurrence of <i>Trichinella</i> spp. on pig farms (<i>Sus scrofa f. domestica</i>) in Poland. In this study, over 194 million pigs, slaughtered for commercial and personal purposes between 2012 and 2020, were tested with a digestion method according to the official rules for <i>Trichinella</i> control. Positive results were noticed in 172 pigs which gives an overall prevalence of 0.000088%. On seven farms, rats (<i>Rattus norvegicus</i>) infected with <i>Trichinella</i> spp. were also discovered. The species identification showed pigs were infected with <i>Trichinella spiralis</i> on 26 farms, and on four farms pigs with <i>Trichinella britovi</i> infections were found. Therefore, it is important to constantly monitor pigs for the presence of these parasites, especially in view of the growing interest in organic meat originated from ecological farms. |
