在丹麦，对肉眼可见霉菌中毒性肾病病变的猪肾脏进行赭曲霉毒素A的分析，如果其浓度超过25μg/kg，则身体不合格。自1982年底以来，这些分析一直在中央进行。讨论了一维薄层层析法的可靠性，并给出了实验室间比较的结果。从1980年到1984年，赭毒症的发病率总体上有所下降，1983年，日德兰北部的地理位置出现了大幅上升。在那一年里，检查了7,639个肾脏；3%的肾脏含有超过150μg/kg，29%的肾脏含有超过25μg/kg的鸵鸟毒素A，相当于每10万头屠宰15只。发病率增加的早期特征是肾脏的毒素水平极高；后来大多数样本呈阴性或接近阴性，因为受影响的猪在屠宰前可能喂了无毒的饲料。根据1983年的数据，讨论了控制程序的有效性。
In Denmark, porcine kidneys displaying macroscopic lesions of mycotoxic nephropathy are analysed for Ochratoxin A and the carcass condemned if the concentration exceeds 25 μg/kg.Since late 1982 these analyses have been conducted centrally. The reliability of the one‐dimensional thin layer chromatographic method is discussed and results from an interlaboratory comparison are presented. From 1980 to 1984 there has been an overall decline in the rate of ochratoxicosis, interrupted in 1983 by a major increase geographically located in the northern half of Jutland. During that year 7639 kidneys were examined; 3% contained more than 150μg/kgand 29% more than 25μg/kg Ochratoxin A, corresponding to a condemnation rate of 15 per 100 000 slaughterings. The early stage of the increased incidence was characterized by kidneys with extremely high levels of the toxin; later most of the samples were negative or near‐negative, as affected pigs were presumably fed a toxin‐free diet before slaughtering. The efficacy of the control program is discussed in view of the 1983 data.
