The presence of antibodies against Trichinella spiralis was investigated in a semi-rural county of Mexico using ELISA and electroimmunotransfer blot assay with crude larvae and ES antigens. The association of antibodies to several social, hygienic and dietary factors was also investigated. Antibody prevalences between 1.0 and 1.9 degrees were found. Risk factors associated were gender female and ingestion of moronga, a pork meat sausage-like product. Our results suggest the presence of an endemic unnoticed form of human trichinellosis. These observations may be relevant for other countries, especially in rural and semi-rural areas, where sylvatic and domestic life-cycles of Trichinella coexist.
