| Popis: | This work examines the presence of pesticides residue levels in beef, chevon, and internal organs obtained from cows and goats slaughtered at Yola Abattoir in Adamawa State.Residues of organochlorines and organophosphorus pesticides were extracted from the meat, chevon and internal organs of the cows and goats using QuEChERS method, and analyzed by GC-MS technique.The residue analysis revealed that beef and chevon samples had no traces of organochlorines whileorganophosphorus (chlorpyrifos, dichlorvos, dichlorpyrifos, diazinon, dimethoate, primifos-methyl, and malathion) pesticide residues detected were below threshold level of 0.01 mg/kg. The result of the animals’ intestine showed the presence of chlorpyrifos (0.034 ± 0.001 vs. 0.031 ± 0.001) and (0.027 ± 0.001 vs.0.023 ± 0.0014) above the standard values, whereas, the dichlorvos level were (0.059 ± 0.0014 vs. 0.050 ± 0.0007), (0.061 ± 0.0007 vs. 0.043 ± 0.0014) and (0.072 ± 0.0014 vs. 0.031 ± 0.001) below the maximum residual value of 1 mg/kg.The kidney residue revealed that dichlorpyrifos, diazinon, dimethoate, primi-methyl and malathion were below the maximum residue limit (0.001 mg/kg) in the cow samples while chlorpyrifos: (0.013 ± 0.001 vs. 0.012 ± 0.001 vs. 0.018 ± 0.001 vs. 0.053 ± 0.001) were above the standard value (0.01 mg/kg). Dichlorvos was detected in the kidney of the goats; (0.069 ± 0.0007 vs. 0.035 ± 0.0014) and (0.052 ± 0.0014) below the maximum residual limit (MRL). Residue analysis in the livers of the cows also showed the presence of chlorpyrifos at (0.011 ± 0.001), (0.014 ± 0.001), (0.08 ± 0.001) above the recommended value, while dichlorvos (1.012 ± 0.001 vs. 0.027 ± 0.001) and (0.029 ± 0.001 vs. 0.037 ± 0.001) were below MRL established by the international health regulation agencies. Residue analysis of all the samples studied shows no trace of organochlorine pesticides. These findings are alarming and are potential threats to the public health. |
