Abstract：
Mycotoxins, such as aflatoxin B1 (AFB1), deoxynivalenol (DON), fumonisins (FBs), ochratoxin A (OTA), T-2 toxin (T-2), and zearalenone (ZEN), can contaminate animal feeds and pose risks to animal health and production performance. These mycotoxins are commonly found in cereals and grains, with the increased use of cereals in pet food, there is a rising concern about mycotoxin contamination among pet owners. To address this, we analyzed imported brands of feline and canine food from the Chinese market produced in 2021-2022. Ninety-three samples were analyzed, comprising 45 feline food and 48 canine food samples. Among them, 14 were canned food and 79 were dry food. The results indicate that AFB1, DON, FBs, OTA, T-2, and ZEN occurred in 32.26%, 98.92%, 22.58%, 73.12%, 55.91%, and 7.53% of the samples, respectively. The most prevalent mycotoxin was DON, followed by OTA, T-2, AFB1, and FBs, whereas ZEN was less frequently detected. The mean concentrations of the six mycotoxins in pet feed samples were 3.17 μg/kg for AFB1, 0.65 mg/kg for DON, 2.15 mg/kg for FBs, 6.27 μg/kg for OTA, 20.00 μg/kg for T-2, and 30.00 μg/kg for ZEN. The levels of mycotoxins were generally below the limits of the Pet Feed Hygiene Regulations of China and the EU. Notably, a substantial majority of the pet food samples (88 out of 93) were contaminated by two or more mycotoxins. AFB1, FBs, OTA, and ZEN occurred slightly more often in feline food than in canine food. Except for OTA, the contamination rates for the other five mycotoxins in canned food were lower than those in dry food. Moreover, except for AFB1, the levels of the other five mycotoxins in canned foods were lower than those in dry foods. This study highlights the widespread contamination of pet foods with mycotoxins, which poses a significant risk to pets from continuous exposure to multiple mycotoxins.
摘要：
霉菌毒素,如黄曲霉毒素B1（AFB1），脱氧雪腐镰刀菌烯醇（DON），伏马菌素（FBs），曲霉毒素A(OTA),T-2毒素(T-2),和玉米赤霉烯酮（ZEN），会污染动物饲料，对动物健康和生产性能构成风险。这些霉菌毒素常见于谷物和谷物中，随着宠物食品中谷物使用的增加，宠物主人对霉菌毒素污染的担忧日益增加。为了解决这个问题，我们分析了2021-2022年生产的来自中国市场的猫和犬食品的进口品牌。分析了93个样本，包括45个猫科动物食物和48个犬科动物食物样本。其中,14是罐头食品，79是干粮。结果表明，AFB1、DON、FBs,OTA,T-2和ZEN的发生率为32.26%，98.92%,22.58%,73.12%,55.91%,和7.53%的样品，分别。最普遍的霉菌毒素是DON,其次是OTA，T-2、AFB1和FB，而ZEN检测频率较低。宠物饲料样品中六种真菌毒素的平均浓度为AFB1为3.17μg/kg，DON为0.65mg/kg，FBs为2.15mg/kg，OTA为6.27μg/kg，T-2为20.00μg/kg,ZEN为30.00μg/kg。真菌毒素的水平通常低于中国和欧盟的宠物饲料卫生法规的限值。值得注意的是,绝大多数宠物食品样本(93个样本中的88个)被两种或更多种真菌毒素污染。AFB1,FBs,OTA,和ZEN在猫科动物食物中比在犬类食物中发生的频率略高。除了OTA,罐头食品中其他五种霉菌毒素的污染率低于干粮。此外，除AFB1外，罐头食品中其他5种真菌毒素的含量均低于干性食品。这项研究强调了真菌毒素对宠物食品的广泛污染，这对宠物连续接触多种霉菌毒素构成了重大风险。
