Biomin's Mycotoxin Survey – Q3

Biomin, specialist in Mycotoxin Risk Management, in the period between April and June 2011, globally collected a total of 1,360 samples which were analyzed and 4,774 analyses were carried out for the most important mycotoxins in terms of agriculture and animal production – aflatoxins (Afla), zearalenone (ZON), deoxynivalenol (DON), fumonisins (FUM) and ochratoxin A (OTA).

Samples tested were diverse, ranging from cereals such as corn, wheat, barley and rice to processing by-products, namely soybean meal, corn gluten meal, dried distillers grains with soluble (DDGS) and other fodders such as straw, silage and finished feed.
 
Figure 1 gives an overview on the distribution of mycotoxins in different world regions.
 
 
 
Figure 2: Global occurrence of mycotoxins between July and September 2011 in the analyzed samples
 
As can be observed in Figure 2, from the 804 survey samples analyzed 24 %, 31 %, 48 %, 50 % and 18 % tested positive for contamination with Afla, ZON, DON, FUM and OTA, respectively.
 
Figure 3: Global co-occurrence of mycotoxins
 
From Figure 3, it is obvious that mycotoxins are an ubiquitous problem as 89 % of the analyzed samples show the presence of, at least, one mycotoxin.
 
The presence of more than one mycotoxin in 35 % of the samples raises the attention to the problem of synergistic effects caused by multiple mycotoxins in animal feeds.
 
Tables 1 to 5 present an overview of the survey with details on analyzed samples. Number of samples tested, percentage of positive samples, average of positive, 75th percentile and maximum levels found are shown. 25 % of the tested samples fall at levels equal to or above those represented by the 75th percentile figure.
