A study of apple juice products sold in Italy and South Africa was initially carried out on 20 samples bought in Cesena, Italy, and Tygerberg in Cape Town, South Africa. The samples were bought at random and analysed for patulin contamination. All 12 of the Italian samples had no detectable levels of patulin, except one, which was just slightly above the lowest regulatory limit of 10 ng ml(-1). On the other hand, five of the eight South African samples were all contaminated with patulin levels above 10 ng ml(-1), with one showing a concentration of 75 ng ml(-1), well above the highest regulated limit of 50 ng ml(-1). This latter result led to a more targeted investigation with 14 samples being purchased in the low-income areas of Tygerberg where the initial samples were sourced. These samples confirmed that there might be a problem of mycotoxin contamination in apple juices products sold to low-income consumers because half of the samples showed patulin contamination of which four had levels well above the acceptable limits. This is the first study in South Africa to look at apple juice products in low-income areas and it points to a need to intervene and introduce quality systems in the supply chain of the manufacture and packaging of apple juice products by independent small business.
一项针对在意大利和南非销售的苹果汁产品的研究最初对从意大利切塞纳和南非开普敦泰格伯格购买的20个样本进行了检测。这些样本是随机购买的，并分析了棒曲霉素污染情况。除了一个样本略高于10 ng/ml的最低监管限值外，所有12个意大利样本均未检测出棒曲霉素。另一方面，8个南非样本中有5个都被棒曲霉素污染，污染水平高于10 ng/ml，其中一个样本的浓度为75 ng/ml，远高于50 ng/ml的最高监管限值。后一结果引发了更有针对性的调查，在最初样本采集地泰格伯格的低收入地区购买了14个样本。这些样本证实，销售给低收入消费者的苹果汁产品可能存在霉菌毒素污染问题，因为一半的样本显示有棒曲霉素污染，其中4个样本的污染水平远高于可接受限度。这是南非首次针对低收入地区的苹果汁产品开展的研究，该研究表明有必要进行干预，并由独立的小企业在苹果汁产品制造和包装的供应链中引入质量体系。
