Global occurrence of mycotoxins in the food and feed chain: facts and figures

Mycotoxins are ubiquitously present in agricultural commodities, such as cereals and oil seeds. If ingested in sufficiently high concentrations, they exert severe toxic effects in humans and animals. In 2004, a survey programme was launched to assess the extent of mycotoxin contamination in feed and feed raw materials. Since then, over 19,000 samples have been analysed and more than 70,000 individual analyses have been conducted. While it is difficult to infer any long-term trends on a global level, the data confirm that high mycotoxin contamination is often linked to unusual weather. Overall, 72% of the samples contained detectable amounts of aflatoxins, fumonisins, deoxynivalenol, zearalenone or ochratoxin A. Co-contamination with two or more mycotoxins was detected in 38% of the samples. In most cases the concentrations were low enough to ensure compliance with EU guidance values or maximum levels. However, co-contaminated samples with concentrations below guidance and maximum values might still exert ...
