Corn plays a central role in Germany’s agricultural economy, accounting for 21% of cultivated land and supporting livestock, food, and energy sectors. However, rising mycotoxin contamination—caused by fungal infections—poses significant risks to food and feed safety, animal health, and value chain productivity. These challenges are expected to intensify due to climate change.
The study analyzes contamination levels in recent years, evaluates the impact of mycotoxins on livestock performance and crop output, and models the broader economic repercussions across the corn value chain. It also explores the benefits and trade-offs of using fungicides to control mycotoxin-producing fungi.
In 2014, corn samples frequently exceeded EU mycotoxin thresholds, reflecting a growing but underrecognized problem.
Contaminated corn feed can lead to reduced milk yield, slower pig weight gain, and substantial losses in livestock productivity.
Economic losses affect not only corn producers but also livestock operations, biogas plants, and food processors.
Climate change is likely to increase the frequency and severity of contamination episodes.
Fungicide use can help reduce mycotoxin levels, but both benefits and risks of such interventions must be carefully evaluated.
The study calls for urgent research and policy action, including better data collection, risk monitoring, and targeted investment in plant protection and crop resilience.
