Climate change (CC) scenarios are predicted to have significant effects on the security of staple commodities. A key component of this impact is the infection of such crops by mycotoxigenic moulds and contamination with mycotoxins. The impacts of CC on mycotoxigenic fungi requires examination of the impacts of the three-way interactions between elevated CO₂ (350–400 vs 650–1200 ppm), temperature increases (+2–5 °C) and drought stress on growth/mycotoxin production by key spoilage fungi in cereals and nuts. This review examines the available evidence on the impacts of interacting CC factors on growth and mycotoxin production by key mycotoxigenic fungi including Alternaria, Aspergillus, Fusarium and Penicillium species. Aspergillus flavus responsible for producing aflatoxin B₁ (AFB₁) is a class 1A carcinogen and its growth appears to be unaffected by CC factors. However, there is a significant stimulation of AFB₁ production both in vitro and in vivo in maize. In contrast, studies on Aspergillus section Circumdati and Nigri species responsible for ochratoxin A contamination of a range of commodities and F. verticillioides and fumonisins suggest that some species are more resilient than others, especially in terms of mycotoxin production. Acclimatisation of mycotoxigenic fungal pathogens to CC factors may result in increased disease and perhaps mycotoxin contamination of staple cereals. Predictive modelling approaches to help identify regions where maximum impact may occur in terms of infection by mycotoxigenic fungi and toxin contamination of staple crops is hindered by the lack of reliable inputs on effects of the interacting CC factors. The present available knowledge is discussed in the context of the resilience of staple food chains and the impact that interacting CC factors may have on the availability of food in the future.

预计气候变化（CC）情景将对大宗商品的安全产生重大影响。这种影响的关键因素是霉菌毒素对这类农作物的感染以及霉菌毒素的污染。CC对霉菌毒素真菌的影响需要检查升高的CO ₂（350–400与650–1200 ppm），温度升高（+ 2–5°C）和干旱胁迫对生长/霉菌毒素之间的三向相互作用的影响。谷物和坚果中主要的腐败菌生产。这项审查审查了关键的致毒素真菌，包括链格孢菌，曲霉，镰刀菌和青霉菌，相互作用的CC因子对生长和真菌毒素产生影响的现有证据。物种。黄曲霉负责产生黄曲霉毒素₁（AFB ₁）是一类1A致癌物，其增长似乎是由CC的因素的影响。然而，在玉米中体外和体内都显着刺激了AFB _1的产生。与此相反，在研究曲霉部Circumdati和Nigri物种负责一系列商品和的赭曲霉毒素A污染F.轮枝伏马菌素和伏马菌素表明某些物种比其他物种更具韧性，尤其是在霉菌毒素的产生方面。霉菌毒素真菌病原体适应CC因子可能导致疾病增加，主粮谷物可能受到霉菌毒素的污染。预测建模方法可帮助确定可能在产毒毒素真菌感染和主粮作物毒素污染方面可能产生最大影响的区域，因为缺乏可靠的输入对相互作用的CC因子的影响而受到阻碍。在主食链的弹性以及相互作用的CC因子可能对将来的食物供应产生影响的背景下讨论了现有知识。
