Ganga freshwater-fish study: qualified evidence
For two freshwater catfish species, Maurya et al. report muscle lead of 2.22 ± 0.22 µg/g in Clupisoma garua and 1.45 ± 0.06 µg/g in Mystus tengara, with cadmium of 0.52 ± 0.02 and 0.39 ± 0.08 µg/g respectively (2019, Table 4; mean ± SD). These Indian market/fisherman samples were collected during 2016–2017. Table 4’s wet-weight label conflicts with the dry-tissue methods, and species-level sample counts are unclear. They cannot be pooled as verified wet-weight concentrations or generalized to all catfish markets.

FDA TDS FY2018–FY2020 source observations
FDA measured the prepared foods named below. Each row describes that food and preparation, not every form of this ingredient. Values are µg/kg (ppb) on the FDA sample basis. ND means not detected; it is not a measured zero. Reporting limits can vary between composites. FY2018-FY2020 TDS Elements Analytical Results
