[Investigations of basic feed quality: Mycotoxins on maize for silage 1997-2003]

Area of Science:

• Agricultural Science
• Food Safety
• Mycotoxicology

Context:

• Long-term monitoring of maize silage quality in Saxony since 1997.
• Annual analysis of approximately 45 samples across diverse regions.
• Focus on the prevalence of Zearalenone (ZEA) and Deoxynivalenol (DON) contamination.

Purpose:

• To assess the occurrence and levels of ZEA and DON in maize for silage.
• To identify potential regional differences in mycotoxin contamination.
• To investigate correlations between toxin levels and agricultural parameters.

Summary:

• Mycotoxins ZEA and DON were detected in 20-90% of analyzed maize silage samples.
• Co-occurrence of both toxins was common, but quantities were generally low.
• Regional hotspots for DON (Erzgebirge) and ZEA (Sächsisches Heideland) were identified.
• No significant correlation found between toxin content and cultivation or pre-fruit factors, likely due to variety and location effects.

Impact:

• Provides crucial data on mycotoxin contamination in German maize silage.
• Informs risk assessment for cattle feed safety and dietary exposure.
• Highlights the need for continued surveillance and regional monitoring strategies.
