Mycotoxins are difficult to monitor continuously, and a tool to assess the risk would help to judge if there is a particular risk due to the inclusion of certain feed ingredients. For this, the toxin contents of 97 commercial fish feeds have been estimated, and the most prominent toxins in fish feed are calculated to be deoxynivalenol, zearalenone, fumonisins and enniatins. These pose a risk to fish well-being, as can be calculated by the Bayesian models for determining the critical concentrations 5% (CC5) for the different toxins. Besides fishmeal, wheat, soybean products and corn are regularly used as fish feed ingredients. The calculated scenarios show that fish are at high risk of toxin contamination if feed ingredients of low quality are chosen for feed production. Due to this, specific maximum allowable levels for several mycotoxins in fish feeds should be established.

欧洲鱼饲料中霉菌毒素污染的风险评估。

霉菌毒素很难连续监测，评估风险的工具将有助于判断是否因添加某些饲料成分而存在特定风险。为此，对 97 种商业鱼饲料的毒素含量进行了估算，计算出鱼饲料中最突出的毒素是脱氧雪腐镰刀菌烯醇、玉米赤霉烯酮、伏马菌素和恩尼亚菌素。这些对鱼类健康构成风险，可以通过贝叶斯模型计算确定不同毒素的临界浓度 5% (CC5)。除鱼粉外，小麦、豆制品和玉米也经常用作鱼饲料成分。计算的情景表明，如果选择低质量的饲料原料进行饲料生产，鱼类受到毒素污染的风险很高。因此，应制定鱼饲料中几种霉菌毒素的具体最大允许含量。
