中文摘要:为了评估乳品生产系统(DPS)中牛奶受霉菌毒素及有机磷和氨基甲酸酯农药残留污染的情况,对巴拉那州三个地区96个DPS进行了调研。收集了牛奶、水和食品样品,并评估了所有样品中的化学残留物及牛奶和食品样品中的黄曲霉毒素。结果发现黄曲霉毒素M1(AFM1)污染牛奶有季节性差异(p< 0,05)。氨基甲酸酯和有机磷的污染源不同(p < 0,01),前者源自控制寄生虫数量的杀虫剂,而后者源于农业生产使用的农药。由食物污染造成的AFM1污染中黄曲霉毒素B1(AFB1)是主要污染源。黄曲霉毒素G1(AFG1)与AFB1的含量显示出的强相关性(p < 0,01)表明真菌菌株同时产生两者是因果关系函数。研究还发现在70%受污染的样品中黄曲霉毒素污染很普遍,并成为各种所分析的食品中与其他霉菌菌毒素相关的优势存在。通过识别污染检查点,可以提议纳入实际的避免此类情况发生的管理方法。
 
外文摘要:Aiming to evaluate the milk contamination in the dairy production
systems (DPS) for mycotoxins and chemical residues of organophosphates and carbamates it was made a study encompassing 96 DPS in three regions of Parana state. There were collected samples of milk, water and food and they were evaluated for chemical residues in all samples and aflatoxin only for food and milk. Mycotoxins in food (aflatoxin B1, B2, G1, G2, zearalenone and ochratoxin) were detected by the method of thin layer chromatography - TLC and for the determination of aflatoxin M1 was used an immunoassay kit competitive ELISA Ridascreen (R). The residues of organophosphates and carbamates were performed by colorimetric method qualitatively. There were evaluated the differences between regions, periods and the sources of mycotoxin contamination. Carbamates and organophosphates were screened for their presence in milk and the sources of food and water. Then it was estimated the contributions of each mycotoxin for milk contamination, as well as their respective contaminated food. Differences were found between periods (p< 0,05) for milk contamination with aflatoxin M1 - AFM1. For carbamates and organophosphates were found different contamination sources (p < 0,01). For the carbamates the source were pesticides used to parasitic herd control and for the organophosphates pesticides used in agriculture. For food sources contamination resulting in the AFM1 contamination it was detected that aflatoxin B1 - AFB1 was the main
source. The aflatoxin G1 - AFG1 showed a strong correlation (p < 0,01) with AFB1 levels suggesting causal relationship is a function of fungal strains producing both at the same time. It was also found the prevalence of aflatoxin contamination in 70% of contaminated samples and its predominant presence in relation to other mycotoxins in all kinds of foods analyzed. By identifying the checkpoints of contamination can be proposed the inclusion of practical management methods to avoid this.
