中文摘要：2010-2014年5年期间，本研究采用ELISA 法分析了919个饲料及其原料样品受黄曲霉毒素B1(AFB(1))污染的情况。结果显示，仅有0.76%的样品中AFB(1)含量不符合欧盟32/2002号法规规定的最高限量，这些样品主要来源于巴里（3个样品， AFB(1) 平均含量为7.03 mu g/kg），而AFB(1)含量最高的2个样品来自福贾和布林迪西，分别达到了 32.6 +/- 3.6 mu g/kg和31.0 +/- 4.0 mu g/kg。从平均水平来看，这些样品虽然受AFB(1)污染，但符合1.4到2.2 mu g/kg的限量范围。考虑到气候条件对产生霉菌毒素的重要性，，为更好地弄清在作物生产、物料储存和/或运输等关键阶段污染水平的变化情况，对分析结果对照取样区的温度和相对环境湿度进行了评估，发现饲料中AFB(1)的含量与气候相关，因此污染程度随季节和年度变化而不同。本研究结果为组织有针对性的监测计划、保护消费者、以及改进动物养殖和饲料生产的质量标准提供了有用的依据。
外文摘要：During a 5-year period from 2010 to 2014, n = 919 samples of feed and raw materials were analyzed for aflatoxin B1 (AFB1) contamination using accredited ELISA screening methods. Only 0.76 % of these samples were non-compliant with maximum levels set by the European Union Regulation 32/2002. Non-compliant samples were mainly from the province of Bari (n = 3 samples, mean AFB1 value 7.03 μg/kg), although the highest AFB1 levels were found in two samples from the provinces of Foggia and Brindisi, at 32.6 ± 3.6 μg/kg and 31.0 ± 4.0 μg/kg, respectively. Mean AFB1 levels in samples contaminated but compliant with the limits ranged from 1.4 to 2.2 μg/kg. Considering the great importance of climate conditions in mycotoxins production, during crops production and during the critical phases of materials storage and/or transport, to better understand the variability in contamination levels, the analytical results were reviewed in term of temperature and relative environmental humidity in the sampling areas. Correlations between aflatoxin B1 levels in feed and these climate factors might explain seasonal and annual variations in contamination levels. The data from the present study provide useful suggestions for the organization of targeted monitoring plans and the protection of consumers, as well as for improvement in the quality standards of zootechnological activities and feed industry.
