Trichinellosis in farmed wild boar: Meat inspection findings and seroprevalence

A reflection of highly prevalent endemic wildlife trichinellosis is seen in wild boar farming in Finland. During the lost five years, 0.7 % (15/2265) of wild boars undergoing official meat inspection have been determined to b e Trichinella-positive. These findings originate from six different farms. In Finland, T. spiralis and T. pseudospiralis have been discovered in meat inspection of wild boars. ELISA showed 11 out of 99 serum samples (11%) as having specific antibodies for T. spiralis crude antigen. Positive samples were from three out of the thirteen farms from which the sera were availabl e. Most of the positive serum samples (8/11) originated from a farm where t richinellosis was also revealed in meat inspection, the other two seroposit ive forms were without previous Trichinella records. Over the last few deco des, ro reports have been made of human trichinellosis acquired in Finland. This indicates both efficient meat inspection as well as public awareness of high-risk foodstuff.
