In an effort to provide further evidence for the hypothesis that a mycotoxin is involved in the aetiology of Balkan endemic nephropathy and that the latter is associated with the occurrence of urinary system tumours, a survey was made of ochratoxin A contamination of cereal samples from an area of Bulgaria where both endemic nephropathy and urinary system tumours are prevalent and from non-endemic areas. In all, 130 samples of beans, maize and wheat flour were analysed. Ochratoxin A levels were 16.7% (25-27 micrograms/kg) in bean samples from the endemic area and 7.1% (25-50 micrograms/kg) in those from the control areas: in maize samples, the levels were 27.3% (25-35 micrograms/kg) and 9.0% (10-25 micrograms/kg), respectively.
为进一步证明霉菌毒素与巴尔干地方性肾病的病因有关，且后者与泌尿系统肿瘤的发生有关这一假说，对来自保加利亚一个地方性肾病和泌尿系统肿瘤都很普遍的地区以及非流行地区的谷物样本中的赭曲霉毒素A污染情况进行了调查。总共分析了130份豆类、玉米和小麦粉样本。流行地区豆类样本中赭曲霉毒素A含量为16.7%（25 - 27微克/千克），对照地区为7.1%（25 - 50微克/千克）；玉米样本中，含量分别为27.3%（25 - 35微克/千克）和9.0%（10 - 25微克/千克）。
