  1. EDI = MC × IR according to Chien et al. (2002)17. Where EDI is the estimated daily intake (mg/kg/day), IR is the daily ingestion rate of imported cattle tissues by a 70-kg person in Egypt: 7.1 g (0.0071 kg) of muscle and 2.39 g (0.00239) of liver, calculated by the USDA (2022)15 and USDA (2020)16, respectively. MC is the metal concentration in bovine samples (mg/kg wet weight) (aJECFA (2010a)44; bEFSA (2010)45; cJECFA (2010b)46.
