这项工作检查了阿达马瓦州约拉屠宰场屠宰的牛和山羊的牛肉、牛肉和内脏中农药残留的水平。采用QuEChERS法从牛、山羊的肉、羊肉和内脏中提取有机氯和有机磷农药残留，并采用气相色谱-质谱联用技术进行分析。残留分析结果显示，牛肉和牛肉样品中未检出有机氯，而有机磷(毒死蜱、敌敌畏、敌敌畏、二嗪农、乐果、甲基咪唑磷和马拉硫磷)农药残留量均低于0.01 mg/kg的阈值。动物运动的结果;肠道中含有毒死蜱(0.034 ±0.001 vs. 0.031;0.001)和(0.027 ±0.001 vs 0.023 ±0.0014)高于标准值，敌敌畏含量为(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.
