“…Based on the results of the in vitro GP experiment, it appears both experimental clays can inhibit the GP compared to the control, but MNM generally was more efficient to reduce GP values than the UM in a dosedependent manner. The UM is known to have an ability for capturing CO 2 (the major component of GP) through a reaction between CO 2 molecules and UM interlayer -OH functional groups to form -HCO 3 , which can in turn react with more interlayer cations thereafter [37]. The higher reduction in GP caused by MNM may indicate the higher absorbance efficiency to capture CO 2 than the UM.…”

“…With the increasingly GHG, the challenge of mycotoxins, especially that of aflatoxin B1 (AFB1) would be of higher importance. Changes in the geographic distribution of mycotoxigenic fungi would also be a result of global warming [ 1 – 3 ]. Thus it seems that mitigation strategies of both GHG and mycotoxins are likely more suitable for the near future.…”

Potential of montmorillonite modified by an organosulfur surfactant for reducing aflatoxin B1 toxicity and ruminal methanogenesis in vitro

Background Montmorillonite clay modified by organosulfur surfactants possesses high cation exchange capacity (CEC) and adsorption capacity than their unmodified form (UM), therefore they may elevate the adverse impact of aflatoxin B1 (AFB1) on ruminal fermentation and methanogenesis. Chemical and mechanical modifications were used to innovate the organically modified nano montmorillonite (MNM). The UM was modified using sodium dodecyl sulfate (SDS) and grounded to obtain the nanoscale particle size form. The dose-response effects of the MNM supplementation to a basal diet contaminated or not with AFB1 (20 ppb) were evaluated in vitro using the gas production (GP) system. The following treatments were tested: control (basal diet without supplementations), UM diet [UM supplemented at 5000 mg /kg dry matter (DM)], and MNM diets at low (500 mg/ kg DM) and high doses (1000 mg/ kg DM). Results Results of the Fourier Transform Infra-Red Spectroscopy analysis showed shifts of bands of the OH-group occurred from lower frequencies to higher frequencies in MNM, also an extra band at the lower frequency range only appeared in MNM compared to UM. Increasing the dose of the MNM resulted in linear and quadratic decreasing effects (P < 0.05) on GP and pH values. Diets supplemented with the low dose of MNM either with or without AFB1 supplementation resulted in lower (P = 0.015) methane (CH4) production, ruminal pH (P = 0.002), and ammonia concentration (P = 0.002) compared to the control with AFB1. Neither the treatments nor the AFB1 addition affected the organic matter or natural detergent fiber degradability. Contamination of AFB1 reduced (P = 0.032) CH4 production, while increased (P < 0.05) the ruminal pH and ammonia concentrations. Quadratic increases (P = 0.012) in total short-chain fatty acids and propionate by MNM supplementations were observed. Conclusion These results highlighted the positive effects of MNM on reducing the adverse effects of AFB1 contaminated diets with a recommended dose of 500 mg/ kg DM under the conditions of this study.

“…That said, the northern European climate is predicted to become milder and more humid toward the year 2050, such that the subsequent associated CC effects will benefit F. graminearum growth (Moretti et al, 2019;Paterson & Lima, 2011). Consistent with that view, recent work by Martínez et al (2022) conducted in Argentina revealed how warm nights can favor the growth of F. graminearum over F. poae in cereal crops, namely, barley and wheat, this decreasing the quality of grain and significantly its increasing mycotoxin contamination. The recent shift in dominance in favor of F. graminearum has also coincided with an increased occurrence of FHB on wheat in southern England (West et al, 2012) and central China (Zhang et al, 2014).…”

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.

“…Southern Europe is predicted to experience increased droughts, while Northern Europe may see greater precipitation; with all trends projected to grow more severe [ 81 ]. The future warmer springs and increased precipitation in Northern Europe are likely to favour Fusarium outbreaks and mycotoxin contaminations [ 80 ], while climate change-induced warmer nights (+3°C) are conditions shown to increase Fusarium disease severity and DON production [ 82 , 83 ]. In contrast, as hot and dry episodes become more prevalent in southern Europe, this will favour increased Aspergillus infections and aflatoxin contamination.…”

Toxigenic fungi, including Aspergillus and Fusarium species, contaminate our major cereal crops with an array of harmful mycotoxins, which threaten the health of humans and farmed animals. Despite our best efforts to prevent crop diseases, or postharvest spoilage, our cereals are consistently contaminated with aflatoxins and deoxynivalenol, and while established monitoring systems effectively prevent acute exposure, Aspergillus and Fusarium mycotoxins still threaten our food security. This is through the understudied impacts of: (i) our chronic exposure to these mycotoxins, (ii) the underestimated dietary intake of masked mycotoxins, and (iii) the synergistic threat of cocontaminations by multiple mycotoxins. Mycotoxins also have profound economic consequences for cereal and farmed-animal producers, plus their associated food and feed industries, which results in higher food prices for consumers. Climate change and altering agronomic practices are predicted to exacerbate the extent and intensity of mycotoxin contaminations of cereals. Collectively, this review of the diverse threats from Aspergillus and Fusarium mycotoxins highlights the need for renewed and concerted efforts to understand, and mitigate, the increased risks they pose to our food and feed cereals.
