A total of 18 pesticides (12 organochlorines, and 6 pyrethroids) in 32 different imported animal liver samples
collected from local markets in Cairo governorate in Egypt in different seasons, were detect the contamination of
organochlorines and pyrethroids pesticides using Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method. The
presence of organochlorines and pyrethroids pesticides residues were determined by gas chromatography with electron
capture detector (GC-ECD). The results indicated that, the pesticides residues were found in all samples and 2 samples above
the maximum residue levels (MRLs). Organochlorine residues had the highest percentage of contamination and violation (i.e.
100 and 6.25%, respectively) in imported animal liver samples, whereas synthetic pyrethroid residues had the lowest
percentage of contamination (i.e. 6.25%) while their percentage of violation were 0%. However, the most frequently found
pesticides were P,P'-DDE and heptachlor-epoxide while the lowest frequently found pesticides were aldrin, cypermethrin
and deltamethrin. Furthermore, the health risk index for heptachlor-epoxide was the greatest which may be due to its
physiochemical properties. A potential regular pesticides residues monitoring program in imported animal liver should be
conducted to protect the consumers' health. |
