World Mycotoxin Report: Impact in 2020
The prevalence of FUM and DON mycotoxins remained high last year, according to the results of the 2019 World Mycotoxin Survey, which was published by Biomin.

Masked mycotoxins are often over- looked in regu- lar mycotoxin tests.
ast year, over 20,000 samples were tested in 86 coun- tries, resluting in a global overview of current myco- toxin prevalence. Overall the survey shows that the occurrence of Fumonisins and Deoxynivalenol re-
mains high in every continent. However, the prevalence of mycotoxins is shifting, explains Annelies Mueller product manager of Biomin in a live webinar: “Due to climate change mycotoxins which were usually found in the southern hemi- sphere are now moving to the north. Mycotoxins are in effect moving with the changing climate.” The World Mycotoxin Sur- vey provides detailed results on the prevalence of mycotoxins for each continent.
Europe In Europe the prevalence of DON and FUM is highest, al- though the prevalence of FUM in 2019 decreased slightly compared with 2018. ZEN is also present in considerable numbers. However the main risk in the EU is the prevalence of
DON. Anneliese Mueller: “This harvest we saw a high preva- lence of DON in cereals and corn. A total of 83% of the corn samples tested positive for DON, followed by FUM (73%). In ce- reals a maximum DON contamination of 21980 ppb was found. The mycotoxin prevalence varies between regions in Europe due to differences in climate and the type of grains harvested. In eastern Europe, DON is the most present mycotoxin and in southern Europe FUM is predominant at 58%.”
North America The prevalence of mycotoxins has increased over the last five- years. Last year’s survey shows a 90% prevalence of DON in finished feed samples which were analysed with a maximum concentration of 8936 ppb. The prevalence of DON in corn samples was 85%, followed by FUM at 78% and ZEN at 55%. In addition, co-contamination was found in 75% of corn samples. ‘Surprisingly, novel plant species that are selected to be resist- ant to the fungi that produce mycotoxin often accumulate a higher percentage of mask mycotoxins compared to non- resistant species,” according to Martina Bellasio, a senior mycotoxin expert at Romer Labs.
Central and South America In Central America the risk level is high, with a prevalence of 69% DON in cereals and 90% FUM in corn, followed by a prev- alence of DON at 56%. The risk level in South America is stated as mid-high with the highest prevalence of FUM and DON being 73% and 63%, respectively.
Asia Asia remains at the same extreme risk level as last year. The prevalence of ZEN and FUM increased in 2019 compared to 2018 and the prevalence of DON remains high. Afla toxins are also a problem. In Asia there was an Afla prevalence of 31% in the corn samples, with a maximum contamination of 773 ppb. In finished feed 99% of the samples were contaminated with FUM.
Africa The risk increased to extreme level this year, mainly due to in- creased contamination with Aflatoxins, which are highly prev- alent in finished feed. The prevalence of DON remained at a high level, as 83% of the samples tested postive, followed by FUM at 78%.
