Coprological based on egg detection in fecal samples and liver inspection to evaluate the presence of the parasite is currently the gold standard for diagnosing chronic fasciolosis in cattle. However, these techniques are labor-intensive and ineffective during the acute phase of the disease. Serodiagnosis using native and recombinant antigens has become an interesting alternative in efforts to identify cattle fasciolosis. We evaluated cattle from abattoir (\n              <jats:italic>n<\/jats:italic>\n              = 139) and farms (\n              <jats:italic>n<\/jats:italic>\n              = 500) through liver inspection and coprological examination, respectively. Our laboratory team optimized and validated enzyme-linked immunosorbent assay tests based on somatic antigen, excretory\/secretory proteins, and the recombinant antigen cathepsin L-1 to detect serum antibodies against fasciolosis in cattle. For animals from abattoir, 10 were positive for fasciolosis according to liver inspection. Both\n              <jats:italic>Fh<\/jats:italic>\n              ES and\n              <jats:italic>Fh<\/jats:italic>\n              rCL-1 presented an area under the receiver operating characteristic (AUROC) curve of 0.80, with a sensitivity of 0.80 (95% CI: 0.46\u20130.95) and 0.70 (95% CI: 0.38\u20130.90) and specificity of 0.81 (95% CI: 0.73\u20130.87) and 0.87 (95% CI: 0.80\u20130.92), respectively. For those cattle from farms, 28 were positive only for fasciolosis according to coprological examination. In this scenario,\n              <jats:italic>Fh<\/jats:italic>\n              ES gave the best performance, with an AUROC of 0.84, sensitivity of 0.79 (95% CI: 0.60\u20130.90), and specificity of 0.86 (95% CI: 0.82\u20130.89). In conclusion, our study highlights the potential of serodiagnosis for accurately screening cattle fasciolosis. The promising sensitivity and specificity values of\n              <jats:italic>Fh<\/jats:italic>\n              ES when compared to liver inspection or coprological examination enhance its importance for cattle fasciolosis diagnosis.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>The aim of this article was to identify antibodies against fasciolosis in cattle in Brazil.
