Mycotoxins, such as Ochratoxins, are widely distributed in nature and are common contaminants of human foodstuffs. Ochratoxins are a group of mycotoxins produced by a wide range of molds. Ochratoxin A (OTA), the most prominent member of this toxin family, is produced by various Aspergillus and Penicillium species. OTA is frequently found in foods such as cereals, oleaginous seeds, coffee, and meat products. This mycotoxin has been described as teratogenic, genotoxic, carcinogenic, and immunotoxic, and has been proven to be a potent neurotoxin. In the present study, the neurotoxicological perspective of OTA was reviewed and discussed. The main possible mechanisms of neurotoxicity are oxidative DNA, protein and lipid damage, and apoptosis. However, further studies are needed to conclude the exact neurotoxicity mechanism of OTA and find the approaches that reduce the neurotoxicity induced by OTA.
期刊介绍：
''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered.
''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
