A total of 172 different salamis were purchased from farms and small salami factories located in four Italian regions (Piedmont, Veneto, Calabria, and Sicily) and analyzed for the presence of ochratoxin A (OTA). Analysis was performed by high-performance liquid chromatography coupled to a fluorimetric detector (HPLC-FLD). The detection limit (LOD) for the method used was 0.05 μg/kg, while the quantitation limit (LOQ) was 0.20 μg/kg; the average recovery rate was 89.1%. OTA was detected in 22 salamis, and 3 samples exceeded the Italian guidance value for OTA in pork meat (1 μg/kg). In particular, what emerges from this research is the high percentage of spicy salamis among positive samples (68.2%, 15 out of 22), although spicy salamis are only 27.3% of the total number of samples collected and analyzed. Red chili pepper contaminated by OTA could be responsible for the presence of the mycotoxin in these spicy salamis. It follow that, also the control of some ingredients used in the manufacture of these meat products, like spices, should not be neglected.
从位于意大利四个地区（皮埃蒙特、威尼托、卡拉布里亚和西西里岛）的农场和小型香肠工厂购买了总共 172 种不同的香肠，并对其是否存在赭曲霉毒素 A（OTA）进行了分析。分析是通过高效液相色谱法与荧光检测器（HPLC-FLD）进行的。所用方法的检测限（LOD）为 0.05μg/kg，定量限（LOQ）为 0.20μg/kg；平均回收率为 89.1%。在 22 种香肠中检测到 OTA，有 3 个样品超过了意大利规定的猪肉中 OTA 的指导值（1μg/kg）。特别是，这项研究的结果显示，阳性样本中辣味香肠的比例很高（68.2%，22 个样本中有 15 个），尽管辣味香肠仅占采集和分析的总样本数的 27.3%。受 OTA 污染的红辣椒可能是这些辣味香肠中存在霉菌毒素的原因。因此，对这些肉类产品制造中使用的一些成分（如香料）的控制也不容忽视。
