BIOMIN Mycotoxin Survey Q2 January to June 2020 Results
Results on the occurrence of mycotoxins in 9,618 in finished feed and raw commodities samples from 68 countries based on 42,505 analyses conducted between January and June 2020.05.08.2020
Mycotoxins are rarely found alone; several mycotoxins tend to co-contaminate feed materials. This holds true in the data analyzed during this half year. A full 68% of all samples (analyzed for at least two mycotoxins) in the first semester of 2020 contained more than one mycotoxin.
In Asia, many regions are again at extreme risk. Risk is especially due to Fusarium mycotoxins in China. In corn (maize), 97% of samples showed occurrence of fumonisins (FUM), deoxynivalenol (DON) and zearalenone (ZEN). South Asia’s livestock is also at extreme risk, with Aflatoxin present in 81% of samples (average of positives at 70 ppb).
Risk in Central America remains extreme. The most prevalent mycotoxins found are FUM and DON (85% and 75%, respectively). In corn, FUM is present in 97% of the samples with an average of 1,913 ppb. As was the case in our Q1 report, we see high risk in DDGS: The Fusarium mycotoxins FUM, DON and ZEN are present in 100% of samples at a high level.
Corn in South America is highly contaminated with FUM at 84% and an average of 2,283 ppb. In wheat bran, DON is the main threat with an average contamination of 2,353 ppb.
In North America the risk remains extreme. Here DON is the most prevalent mycotoxin found (81%), followed by FUM and ZEN (48% and 47%). Taking a look at corn, we see a high prevalence of the same mycotoxins with increased averages of 2,172 ppb (FUM), 801 ppb (DON) and 375 ppb (ZEN). This shows that corn is severely affected.
Corn in Southern Europe shows a high prevalence of FUM with 98%. The average is also high at 1,636 ppb. In addition, corn silage in this region also shows a high FUM contamination (94% with 3,413 ppb of average).
In Central Europe, the risk stays severe: Corn shows an 85% prevalence of DON with an average of 958 ppb.
Interestingly, in Northern Europe, straw shows a high DON contamination with an average of 531 ppb.
Middle East and North Africa
In this region, prevalence of DON increased 77% compared with the same half of 2019. It recorded a maximum of 5,170 ppb.
In South Africa, we see that DON is the most prevalent mycotoxin. In particular, corn is highly contaminated with DON: 91% (average: 920 ppb).
Spectrum 380® results
Spectrum 380® is the most comprehensive mycotoxin detection method available. BIOMIN analyzed 440 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 30% of the samples contained between 40-49 metabolites (per sample). Results for emerging mycotoxins show that Beuvericin and Enniatin B and B1 were present in 100% of finished feed. Culmorin was also present in 80% of the samples analyzed. An average of 808 ppb was found. Literature suggests that this mycotoxin could increase the toxic effects of DON. Interestingly, analysis revealed the presence of DON in 80% of the samples as well.
