Abstract

This study presents the results of aflatoxin contamination of maize and groundnuts in major markets in Accra and assesses the population's exposure to aflatoxins. Raw maize and groundnuts from 6 major markets in Accra were sampled and analysed for their aflatoxin content. A total of 92 samples comprising 48 maize and 44 groundnuts were analysed using high-performance liquid chromatography, after extraction with methanol/water and cleanup on an immunoaffinity column. Total aflatoxins were quantified in 98% of the maize samples and 70% of the groundnut samples, with concentrations ranging from 0.60 to 1065 µg/kg and 0.20 to 627 µg/kg, respectively. Exposure assessment showed an estimated daily intake of 0.436 μg/kg bw/day and 0.0632 μg/kg bw/day for maize and groundnut consumption, respectively, suggesting significant health risks for consumers. The high prevalence and concentrations of aflatoxins call for an urgent need for measures to control exposure of the Ghanaian population.

阿克拉市场上玉米和花生中的黄曲霉毒素与消费者风险。

本研究介绍了阿克拉主要市场的玉米和落花生黄曲霉毒素污染情况，并评估了人们接触黄曲霉毒素的情况。研究人员对阿克拉 6 个主要市场的玉米和花生原料进行了采样，并对其黄曲霉毒素含量进行了分析。经甲醇/水提取和免疫亲和柱净化后，采用高效液相色谱法对包括 48 个玉米和 44 个花生在内的 92 个样本进行了分析。98%的玉米样本和70%的落花生样本中的黄曲霉毒素总量被定量，浓度范围分别为每公斤0.60至1065微克和每公斤0.20至627微克。暴露评估显示，玉米和落花生的估计日摄入量分别为 0.436 微克/千克体重/天和 0.0632 微克/千克体重/天，这表明消费者的健康面临重大风险。黄曲霉毒素的高流行率和高浓度要求采取紧急措施，控制加纳人口的黄曲霉毒素摄入量。

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.
