A survey on 73 milk samples from different animal breeds and 24 dairy products samples from Sicily, Italy, was carried out for the presence of aflatoxin M₁ (AFM1) by LC-fluorescence detection after immunoaffinity cleanup. AFM1 was detected in 48% and 42% of the milk and dairy samples at concentration ranges between <5.0-16.0 and <5.0-18.0 ng L⁻¹, respectively. Within the raw milk samples, 92% had an AFM1 content below 5.0 ng L⁻¹, in 7% of the cases it was in the range 5.0-10.0 ng L⁻¹ and 1% was contaminated between 10.0 and 20.0 ng L⁻¹. For the dairy products, ultra-high-temperature treated (UHT) milk, milk cream and cheese, the incidence was 42%, of which 83% contained less than 5.0 ng L⁻¹ and 17% contained 10.0-20.0 ng L⁻¹ AFM1. The levels of contamination found justify continuous monitoring for public health and to reduce consumer exposure.
对来自意大利西西里岛的 73 个不同动物品种的牛奶样本和 24 个乳制品样本进行了调查，通过免疫亲和净化后的 LC-荧光检测法检测黄曲霉毒素 M₁（AFM1）的存在。在牛奶和乳制品样本中，分别有 48%和 42%的样本在 5.0-16.0 和 <5.0-18.0ng L⁻¹浓度范围内检测到 AFM1。在生牛乳样本中，92%的样本中 AFM1 的含量低于 5.0ng L⁻¹，7%的样本中含量在 5.0-10.0ng L⁻¹之间，1%的样本中含量在 10.0-20.0ng L⁻¹之间。对于超高温处理（UHT）牛奶、奶油和奶酪等乳制品，检出率为 42%，其中 83%的样本中 AFM1 含量低于 5.0ng L⁻¹，17%的样本中 AFM1 含量在 10.0-20.0ng L⁻¹之间。发现的污染水平证明需要持续监测以保障公众健康并降低消费者的暴露风险。
