Abstract
Aflatoxin (AF) contamination of crops during the pre-harvest period is a significant global concern for food and feed safety (FFS). In Europe, climate change presents a growing threat to agricultural products by increasing the risk of AF contamination. This umbrella review evaluates the scope and quality of pre-harvest data on climate-related AF contamination in Europe, addressing key questions: What insights do researchers provide on the relationship between climate change and pre-harvest AF contamination, and what data are lacking? Which crops are the focus of current research, and where in Europe are these studies concentrated? How is the data presented, and is it standardized? We conducted an umbrella literature review, extracting relevant studies from PubMed and Scopus up to 14 October 2024. Our findings indicate that rising temperatures, droughts, and shifting rainfall patterns increasingly favor the growth of aflatoxigenic fungi and pre-harvest AF contamination in European crops, posing risks to FFS and agricultural stability. However, inconsistencies in data collection and reporting limit cross-regional comparisons and hinder the development of effective mitigation strategies. Standardizing methodologies and improving data accessibility will enhance predictive modeling, strengthen risk assessments, and support targeted adaptation efforts, providing actionable insights for policymakers and agricultural stakeholders.
