What is Climate Change Impact on Mycotoxin Occurrence?

Climate Change Impact on Mycotoxin Occurrence examines how rising temperatures, altered precipitation, and extreme weather influence the distribution, growth, and toxin production of mycotoxigenic fungi in crops.

Researchers model shifts in Aspergillus flavus and Fusarium species under IPCC climate projections, predicting increased aflatoxin B1 in European maize (Battilani et al., 2016, 611 citations). Studies show warmer conditions and drought favor pre- and post-harvest contamination (Magan et al., 2011, 376 citations; Paterson and Lima, 2009, 567 citations). Over 20 papers since 2007 quantify these effects across global staples like maize and wheat.

Key Challenges

Why It Matters

Predicted aflatoxin increases in Europe due to climate change threaten maize supply chains and exceed EU limits, requiring predictive modeling (Battilani et al., 2016). Drought and heat shift Fusarium toxins in cereals, impacting animal feed and human health regulations (Magan et al., 2011). Global aflatoxin hotspots expand in maize and nuts, driving $1B+ annual losses and adaptive breeding needs (Jallow et al., 2021; Medina et al., 2014).

Key Research Challenges

Predicting Regional Toxin Hotspots

Modeling interacts between local climate projections and fungal ecophysiology remains uncertain for non-maize crops. Battilani et al. (2016) predict aflatoxin rises in Europe but lack validation for Asia. Multi-model ensembles needed for robust forecasts (Paterson and Lima, 2009).

Quantifying Drought-Toxin Interactions

Drought favors Aspergillus flavus growth but suppresses aflatoxin at extremes, complicating predictions. Magan et al. (2011) review water stress effects pre-harvest. Field data scarce versus lab studies (Medina et al., 2014).

Integrating Post-Harvest Risks

Storage conditions amplify climate-driven field contamination under warming scenarios. Klich (2007) details A. flavus persistence in seeds. Projections ignore supply chain variability (Jallow et al., 2021).
