Abstract:
Climate change (CC) is a complex phenomenon that has the potential to significantly alter marine, terrestrial, and freshwater ecosystems worldwide. Global warming of 2°C is expected to be exceeded during the 21st century, and the frequency of extreme weather events, including floods, storms, droughts, extreme temperatures, and wildfires, has intensified globally over recent decades, differently affecting areas of the world. How CC may impact multiple food safety hazards is increasingly evident, with mycotoxin contamination in particular gaining in prominence. Research focusing on CC effects on mycotoxin contamination in edible crops has developed considerably throughout the years. Therefore, we conducted a comprehensive literature search to collect available studies in the scientific literature published between 2000 and 2023. The selected papers highlighted how warmer temperatures are enabling the migration, introduction, and mounting abundance of thermophilic and thermotolerant fungal species, including those producing mycotoxins. Certain mycotoxigenic fungal species, such as Aspergillus flavus and Fusarium graminearum, are expected to readily acclimatize to new conditions and could become more aggressive pathogens. Furthermore, abiotic stress factors resulting from CC are expected to weaken the resistance of host crops, rendering them more vulnerable to fungal disease outbreaks. Changed interactions of mycotoxigenic fungi are likewise expected, with the effect of influencing the prevalence and co-occurrence of mycotoxins in the future. Looking ahead, future research should focus on improving predictive modeling, expanding research into different pathosystems, and facilitating the application of effective strategies to mitigate the impact of CC.
摘要:
气候变化(CC)是一种复杂的现象,有可能显着改变海洋,陆地,全球淡水生态系统。预计21世纪全球变暖将超过2°C,以及极端天气事件的频率,包括洪水,风暴,干旱,极端温度,和野火,近几十年来在全球范围内愈演愈烈,以不同的方式影响世界各地。CC如何影响多种食品安全危害越来越明显,特别是霉菌毒素污染日益突出。多年来,有关CC对食用作物中霉菌毒素污染的影响的研究取得了长足的发展。因此,我们进行了全面的文献检索,以收集2000年至2023年发表的科学文献中的可用研究.选定的论文强调了温暖的温度如何使迁移成为可能,介绍,越来越多的嗜热和耐热真菌物种,包括那些产生霉菌毒素的.某些霉菌毒性真菌,如黄曲霉和镰刀菌,预计将容易适应新的条件,并可能成为更具侵略性的病原体。此外,CC引起的非生物胁迫因素有望削弱寄主作物的抗性,使他们更容易受到真菌病爆发的影响。同样,预期会改变霉菌毒性真菌的相互作用,具有影响未来霉菌毒素的流行和共现的作用。展望未来,未来的研究应该集中在改进预测建模上,将研究扩展到不同的病理系统,并促进应用有效的策略来减轻CC的影响。
