The presence of carcinogenic substances in beef poses a significant risk to public health, with far-reaching implications for consumer safety and the meat production industry. Despite advancements in food safety measures, traditional breeding methods have proven inadequate in addressing these risks, revealing a substantial gap in knowledge. This review aims to fill this gap by evaluating the potential of healthy breeding techniques to significantly reduce the levels of carcinogenic compounds in beef. We focus on elucidating the molecular pathways that contribute to the formation of key carcinogens, such as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), while exploring the transformative capabilities of advanced genomic technologies. These technologies include genomic selection, CRISPR/Cas9, base editing, prime editing, and artificial intelligence-driven predictive models. Additionally, we examine multi-omics approaches to gain new insights into the genetic and environmental factors influencing carcinogen formation. Our findings suggest that healthy breeding strategies could markedly enhance meat quality, thereby offering a unique opportunity to improve public health outcomes. The integration of these innovative technologies into breeding programs not only provides a pathway to safer beef production but also fosters sustainable livestock management practices. The improvement of these strategies, along with careful consideration of ethical and regulatory challenges, will be crucial for their effective implementation and broader impact.
牛肉中致癌物质的存在对公众健康构成重大风险,对消费者安全和肉类生产行业产生深远影响。尽管食品安全措施有所进步,但传统育种方法已被证明不足以应对这些风险,这揭示了知识上的巨大差距。本综述旨在通过评估健康育种技术显著降低牛肉中致癌化合物水平的潜力来填补这一差距。我们专注于阐明导致关键致癌物形成的分子途径,如杂环胺(HCAs)和多环芳烃(PAHs),同时探索先进基因组技术的变革能力。这些技术包括基因组选择、CRISPR/Cas9、碱基编辑、引导编辑以及人工智能驱动的预测模型。此外,我们研究多组学方法,以深入了解影响致癌物形成的遗传和环境因素。我们的研究结果表明,健康育种策略可以显著提高肉质,从而为改善公众健康状况提供独特机会。将这些创新技术整合到育种计划中,不仅为更安全的牛肉生产提供了途径,还促进了可持续的畜牧管理实践。改进这些策略,并仔细考虑伦理和监管挑战,对于其有效实施和更广泛的影响至关重要。
