Mycotoxins, being a threat to animal and human health, contribute significantly towards economic losses in the poultry sector. A liquid chromatography-mass spectrometry-based study was conducted on poultry feed samples collected from Punjab, Pakistan to evaluate the prevalence, contamination levels, and co-occurrence of multi-mycotoxins across different processed forms of the feed, types of utilities and sampling regions. All samples were found to be contaminated with aflatoxin B1 (AFB1) and fumonisin B1 (FB1). The European Commission (EC) maximum level for AFB1 in complete feedingstuffs in poultry and guidance values for FB1 and zearalenone (ZEN) were exceeded in 73%, 2%, and 14% of the contaminated samples, respectively. The corresponding median values were 39.9 µg/kg, 205 µg/kg, and 34.5 µg/kg. In addition to exceeding contamination levels, a varying co-occurrence of three to fourteen mycotoxins was observed in each of the feed samples that calls for mitigation measures to safeguard the feed and its ingredients.
霉菌毒素对动物和人类健康构成威胁，给家禽业造成了重大经济损失。对从巴基斯坦旁遮普省采集的家禽饲料样本进行了一项基于液相色谱 - 质谱联用的研究，以评估不同加工形式的饲料、使用类型和采样区域中多种霉菌毒素的流行情况、污染水平和共存情况。所有样本均被发现受到黄曲霉毒素B1（AFB1）和伏马毒素B1（FB1）的污染。受污染样本中，分别有73%、2%和14%超过了欧盟委员会（EC）规定的家禽全价饲料中AFB1的最高限量以及FB1和玉米赤霉烯酮（ZEN）的指导值。相应的中位数分别为39.9微克/千克、205微克/千克和34.5微克/千克。除了超标污染水平外，在每个饲料样本中还观察到三至十四种霉菌毒素的不同共存情况，这就需要采取缓解措施来保护饲料及其成分。
