The aim of this work was to investigate the current situation of Trichinella infection from domestic pigs in the historical endemic areas of Henan province, central China. A total of 823 diaphragm samples from the indoor-raised pigs were collected in five cities of Henan during 2014-2015 and examined by artificial digestion method. The overall prevalence of Trichinella infection in pigs was 0.61 % (5/823). Trichinella larvae were detected in 0.91 % (5/550) of pigs from Nanyang city of Henan. The larval burden in infected animals was 0.03 larvae per gram (lpg) of muscles with a range from 0.02 to 0.05 lpg. The larvae were identified as Trichinella spiralis by multiple PCR. Our study confirms the existence of swine trichinellosis in Henan, but the infection level was under the minimum level for defining infectious sources for humans. However, the prevalence of swine Trichinella infection in Henan need to be further evaluated with a large scale of pork samples for ensuring meat food safety.
