Abstract

Co-occurrence of aflatoxins (AFs) and Ochratoxin A (OTA) in staple foods in Morocco was investigated, and the associated dietary exposure was assessed. A total of 135 samples of biscuits, chips, rice, black olives, and maize were collected from various markets and analysed using immunoaffinity column clean-up followed by HPLC-FLD. AFs and OTA were detected in 8.2% of the samples, maize being the most contaminated. AFB1 in 1 rice sample reached 8.5 µg/kg, exceeding the national limit and the OTA level in 1 maize sample was 24 µg/kg, above the regulatory limit of Morocco. Exposure assessment estimated daily intakes of 1.55 and 0.039 ng/kg bw/day for OTA from maize and olives, respectively. Mycotoxin levels above regulatory limits in staple foods indicate a public health risk and underscore the need for strict monitoring and control in the Moroccan food supply chain.

摩洛哥食品中的黄曲霉毒素和赭曲霉毒素A及其健康风险评估。

调查了摩洛哥主食中黄曲霉毒素（AFs）和赭曲霉毒素A （OTA）的共存情况，并评估了相关的饮食暴露。从不同市场共收集了135份饼干、薯片、大米、黑橄榄和玉米样品，并使用免疫亲和柱清理和HPLC-FLD进行分析。8.2%的样品中检出AFs和OTA，其中玉米污染最严重。1份水稻样品中AFB1含量达8.5µg/kg，超过国家标准；1份玉米样品中OTA含量为24µg/kg，超过摩洛哥标准。暴露评估估计，来自玉米和橄榄的OTA每日摄入量分别为1.55和0.039纳克/千克体重/天。主食中霉菌毒素水平超过监管限制表明存在公共健康风险，并强调需要对摩洛哥食品供应链进行严格监测和控制。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
