AFB and OTA are produced in food products due to climatic conditions like temperature and humidity. In Lebanon, few studies address AFB and OTA contamination in wheat and wheat products. In this study, a total of 312 samples of wheat and wheat products were collected from different sites, including port, silos, mills, and supermarkets were analysed. Wheat and wheat products consumption in Lebanon was quantified using a food frequency questionnaire. Exposure to AFB and OTA was calculated and liver and kidney cancer risk were evaluated. Results showed that AFB and OTA were, respectively, found in 65.7% and 100% of the samples, with 0.6% and 17.6% exceeding the maximum limit set by the European Commission. AFB was shown to be associated with 0.076 additional cancer cases per 100,000 persons per year and OTA weekly exposure was shown to be 53.2 ng/kg bw, which is less than the Provisional Tolerable Weekly Intake of 100 ng/kg bw.
AFB 和 OTA 会因温度和湿度等气候条件而在食品中产生。在黎巴嫩，很少有研究涉及小麦和小麦制品中的 AFB 和 OTA 污染。在这项研究中，共采集了来自不同地点（包括港口、筒仓、磨坊和超市）的 312 份小麦和小麦制品样本进行分析。使用食物频率问卷来量化黎巴嫩的小麦和小麦制品的消费情况。计算了接触 AFB 和 OTA 的情况，并评估了肝癌和肾癌的风险。结果表明，在 65.7%的样本中发现了 AFB，在 100%的样本中发现了 OTA，分别有 0.6%和 17.6%的样本超过了欧盟委员会设定的最大限量。研究表明，AFB 每年每 10 万人会导致额外增加 0.076 例癌症病例，而 OTA 的每周暴露量为 53.2ng/kg bw，低于暂定每周耐受摄入量 100ng/kg bw。
