Aflatoxin contamination and health risk assessment in maize in Gansu Province in 2023.
Aflatoxins (AFs) are one of the most toxic mycotoxins that can easily contaminate agricultural products and have adverse effects on both humans and animals. To understand the AF contamination in maize in Gansu Province and the risk of dietary exposure, LC-MS was used to determine the AFs in maize in Gansu Province in accordance with national standards. The results showed that the concentration range of AFs detected in maize was ND ∼15.9 μg/kg, and the detection rates of AFB1, AFB2, AFG1 and AFG2 were 13.3%, 5%, 6.7% and 4.2%, respectively. The estimated daily intake and margin of exposure (MOE) for infants, children, adolescents, and adults were 0.00575-0.0197 µg/kg bw/d, and 69.56-20.34, respectively. The consumption of maize may have adverse health effects in all age groups studied as all calculated MOEs were less than 10,000.
期刊介绍：
Food Additives & Contaminants: Part A publishes original research papers and critical reviews covering analytical methodology, occurrence, persistence, safety evaluation, detoxification and regulatory control of natural and man-made additives and contaminants in the food and animal feed chain. Papers are published in the areas of food additives including flavourings, pesticide and veterinary drug residues, environmental contaminants, plant toxins, mycotoxins, marine biotoxins, trace elements, migration from food packaging, food process contaminants, adulteration, authenticity and allergenicity of foods. Papers are published on animal feed where residues and contaminants can give rise to food safety concerns. Contributions cover chemistry, biochemistry and bioavailability of these substances, factors affecting levels during production, processing, packaging and storage; the development of novel foods and processes; exposure and risk assessment.
