This study investigated the status of DDT and its metabolite levels in ninety\u2010six samples of two commercially available and widely consumed dried fish species,\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Harpadon nehereus<\/jats:italic>\n                    <\/jats:styled-content>\n                    and\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Trichiurus lepturus<\/jats:italic>\n                    <\/jats:styled-content>\n                    , collected across the country. The samples were extracted using the solid\u2010phase dispersion technique and analyzed by GC\u2010ECD. The analytical methodology showed excellent sensitivity and linearity with LOD ranging from 0.30 to 0.39\u2009\u03bcg\/kg, LOQ from 0.92 to 1.18\u2009\u03bcg\/kg, and regression coefficient (\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>\n                      <jats:italic>2<\/jats:italic>\n                    <\/jats:sup>\n                    )\u2009\u2265\u20090.9991. The parent pesticide, 4,4\u2032\u2010DDT, was found in 10 out of 96 samples, with concentrations spanning from 1.41 to 11.02\u2009\u03bcg\/kg. The two metabolites, 4,4\u2032\u2010DDE and 4,4\u2032\u2010DDD, were more frequently detected among the analyzed specimens, with total DDTs (\u03a3DDTs) reaching up to 29.40\u2009\u03bcg\/kg. The contamination pattern and the proportion of 4,4\u2032\u2010DDT to \u03a3DDTs suggested historical exposure to DDT in the food chain rather than recent application. The health risk assessment demonstrated no potential non\u2010carcinogenic risk, as the hazard quotient remained well below the threshold limit (&lt;\u20091). The incremental lifetime cancer risk (ILCR) predominantly fell in the negligible risk range (&lt;\u20091\u2009\u00d7\u200910\n                    <jats:sup>\u22126<\/jats:sup>\n                    ); however, a few samples (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20097) showed elevated cumulative exposure (\u03a3ILCR) but were still confined within the tolerable risk boundary (1\u2009\u00d7\u200910\n                    <jats:sup>\u22126<\/jats:sup>\n                    to 1\u2009\u00d7\u200910\n                    <jats:sup>\u22124<\/jats:sup>\n                    ) set by USEPA.
