The aim of this study was to investigate the occurrence of the most common mycotoxins in commercial dry dog food using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Aflatoxin B1 (AFB1), aflatoxin G1 (AFG1), zearalenone (ZEN), deoxynivalenol (DON), T-2, beauvericin (BEA), citrinin (CIT), ochratoxin A (OTA), fumonisin B1 (FB1) were included in this study. The results showed that all these analytes could be found in the samples. Furthermore, only one sample was found free of mycotoxins contamination. All other samples (96.9%) were contaminated by at least three different types of mycotoxins. Among these mycotoxins, DON, ZEN, AFB1, FB1, CIT and BEA exhibited relatively high incidence, with occurrence rates of 78.1%, 62.5%, 87.5%, 93.8%, 68.8 and 96.9%, respectively. Furthermore, it is worth noting that AFB1 concentration in all AFB1 positive samples exceeded the maximum limits set by the European Union, with concentrations ranging from 30.3-242.7 µg/kg.
本研究的目的是使用液相色谱-串联质谱法（LC-MS/MS）调查市售干狗粮中最常见霉菌毒素的存在情况。本研究纳入了黄曲霉毒素B1（AFB1）、黄曲霉毒素G1（AFG1）、玉米赤霉烯酮（ZEN）、脱氧雪腐镰刀菌烯醇（DON）、T-2毒素、白僵菌素（BEA）、桔霉素（CIT）、赭曲霉毒素A（OTA）、伏马菌素B1（FB1）。结果表明，所有这些分析物均可在样品中检测到。此外，仅发现1个样品未受霉菌毒素污染。所有其他样品（96.9%）均受到至少三种不同类型霉菌毒素的污染。在这些霉菌毒素中，DON、ZEN、AFB1、FB1、CIT和BEA的检出率相对较高，发生率分别为78.1%、62.5%、87.5%、93.8%、68.8%和96.9%。此外，值得注意的是，所有AFB1阳性样品中的AFB1浓度均超过了欧盟设定的最大限量，浓度范围为30.3-242.7µg/kg。
