BIOMIN Mycotoxin Survey Q3 2020 Results
Results on the occurrence of mycotoxins in 15,544 finished feed and raw commodities samples from 74 countries based on 68,683 analyses conducted between January and September 2020.05.11.2020
It is commonly observed that single mycotoxins are rarely found alone. Different mycotoxins tend to co-contaminate feed materials. This is also valid for the data analyzed during this year. A full 68% of all samples (analyzed for at least two mycotoxins) in the first three quarters of 2020 contained more than one mycotoxin.
Most regions in Asia are at extreme risk. Livestock in China is exposed to a cocktail of Fusarium mycotoxins. In corn (maize), 98% of samples showed occurrence of fumonisins (FUM), deoxynivalenol (DON) and zearalenone (ZEN). South Asia shows a severe risk with Aflatoxin particularly appearing in 81% of samples (average of positives at 50 ppb).
Risk in Central America remains extreme. FUM and DON are again the most frequently found mycotoxins (82% and 78%). Taking a look at corn, FUM is present in 97% of the samples with an average of 1,839 ppb. Be aware of Fusarium mycotoxins in DDGS: FUM, DON and ZEN are present in 98%, 100% and 98% of the samples at a high level.
Corn in South America is highly contaminated with FUM at 83% and an average of 2,257 ppb. In wheat bran, DON is the main threat with an average contamination of 2,283 ppb.
In North America the risk is still extreme. Again, DON shows a high prevalence (79%), followed by FUM and ZEN (50% and 46%). Corn is strongly affected with a similar high prevalence and averages of 2,166 ppb (FUM), 787 ppb (DON) and 350 ppb (ZEN).
Corn in Southern Europe shows a high prevalence of FUM with 98%. The average is also high: 1,654 ppb. In addition, in this region corn silage shows a high FUM contamination (91% with 3,462 ppb on average).
In Central Europe, risk stays severe: corn shows 87% occurence of DON and an average of 935 ppb.
In Northern Europe, straw shows a high DON contamination with an average of 485 ppb.
Middle East and North Africa
In this region, prevalence of DON was at 79%, an increased compared with the same quarter of 2019. A maximum of 5,170 ppb was observed.
Having a closer look at South Africa, we see that DON is the most prevalent mycotoxin here. Corn in particular is highly contaminated, with occurrence of DON at 94% (average: 713 ppb).
Spectrum 380® results
Spectrum 380® is the most comprehensive mycotoxin detection method available. BIOMIN analyzed 829 samples in 2020 using this advanced technique. The method shows us occurrence of not only the well-known mycotoxins, but also emerging mycotoxins and other fungal metabolites that are often not considered in regular analysis, but could still disrupt animal production.
Analysis results show that 20% of the samples contained between 40-49 metabolites (per sample). Results for emerging mycotoxins show that Beauvericin and Enniatin B and B1 were present in 97% and 93%, respectively, of finished feed samples. Culmorin was also present in 73% of the samples analyzed. An average of 640 ppb was found. Literature suggests that this mycotoxin could increase the toxic effects of DON.
