摘要：A total of 60 samples of milk powder representative as 40 canned and20 un-canned were collected from groceries, pharmacy and supermarkets from different localities in Alexandria city for detection of toxic heavy metal residues including (Pb, Cd, Al and tin) and mycotoxins including (AFM1, AFM2 and Ochratoxin A); The obtained results could be summarized as: - Lead was detected in 6 (15%) and 7(35%) of examined (canned and un-canned milk powder) with a mean values of 0.25±0.06 and 0.12±0.04 ppm, the samples exceeded the permissible limit 3(50%) and 4(57.14%) respectively. Cadmium residues was detected in 5 (12.5%) and 6 (30 %) of examined (canned and un-canned milk powder) with a mean values of 0.08 ± 0.02 and 0.11 ± 0.02 ppm, the samples exceeded the permissible limit 2 (40%) and 3 (50%) respectively. Aluminium was detected in 3 (7.5%) and 5 (25 %) of examined (canned, and un-canned milk powder) with a mean values of 0.45 ± 0.12 and 0.37 ± 0.15 ppm, the samples exceeded the permissible limit 1(33.33%) and 4(80%) respectively. Tin was detected in 2 (5%) and 8 (40 %) of examined (canned, and un-canned milk powder) with a mean values of 26.8 ± 5.13 and 49.9 ± 5.50 ppm, respectively. All positive samples with in the permissible limit. AFM1 was detected in 2 (5%) and 3 (15%) in examined milk powder (canned and un-canned) samples with a mean values of 0.033 ± 0.02 and 0.507 ± 0.21 ppb, the samples exceeded the permissible limit 0 (0%) and 3 (100%) respectively. AFM2 was detected in 1 (2.50 %) in examined milk powder (canned) samples with a mean values of 0.013 (ppb).and the positive samples whit in permissible limit. Ochratoxin A OTA was not detected in all (canned, and un-canned) milk powder samples.
