The objective of this study was to investigate if milk from dairy sheep and goats, fed mainly with supplementary feed during the winter months, was contaminated with pesticides residues. Tauwo hundred milk samples from sheep and goats were collected from 10 farms of each animals. The sheep and goats farms were selected from those which represent common conventional production and feeding systems in Greece. Milk and feed samples (alfalfa hay, wheat straw, shrubs, pasture and concentrates) were taken from each farm to analyze for pesticides residues. The results showed that the summation operatorendosulfan was the main pesticide residue which was detected in all the concentrates samples at a mean concentration of 5.36 mgkg(-1), which is much higher from the maximum residue level (MRL). In addition, the summation operatorendosulfan was also detected in all the alfalfa hay samples but at a mean concentration of 0.10 mgkg(-1) which is lower than the MRL. The mean concentrations of endosulfan alpha and beta were 2.82 and 2.39 mgkg(-1) in the concentrates samples and 0.08 and 0.02 mgkg(-1) respectively in alfalfa hay samples. In the wheat straw, shrubs and pasture samples no pesticides residues were detected. No pesticide residues were also detected in milk samples of sheep and goats. Thus, this milk from the farms sampled presents no human health risks as far as the contaminants analyzed concerned.
本研究旨在调查冬季主要以补充饲料喂养的绵羊和山羊奶是否受到农药残留的污染。从 10 个绵羊和山羊养殖场采集了 200 份奶样。这些养殖场是从希腊常见的常规生产和饲养系统中选择的。从每个养殖场采集奶样和饲料样（紫花苜蓿干草、小麦秸秆、灌木、牧场和浓缩饲料）进行农药残留分析。结果表明，硫丹总和是所有浓缩饲料样品中检测到的主要农药残留，平均浓度为 5.36mg/kg，远高于最大残留限量（MRL）。此外，硫丹总和也在所有紫花苜蓿干草样品中检出，但平均浓度为 0.10mg/kg，低于 MRL。浓缩饲料中硫丹 α 和 β 的平均浓度分别为 2.82mg/kg 和 2.39mg/kg，紫花苜蓿干草中的平均浓度分别为 0.08mg/kg 和 0.02mg/kg。在小麦秸秆、灌木和牧场样品中未检测到农药残留。绵羊和山羊奶样中也未检测到农药残留。因此，就所分析的污染物而言，这些来自采样农场的牛奶不会对人类健康造成风险。
