Biomin released details on the distribution of mycotoxins according to region of origin and commodity type in its latest Mycotoxin Survey Program 2012. The survey confirmed that mycotoxins are a persistent problem around the world, with 82 percent of analyzed samples showing presence of at least one mycotoxin and more than one mycotoxin in 50 percent of the samples.
From January until December 2012, a total of 4,023 mycotoxin samples collected worldwide were analyzed. In total, 14,468 analyses were carried out for the most important mycotoxins in terms of agriculture and animal production â€“ aflatoxins (Afla), zearalenone (ZEN), deoxynivalenol (DON), fumonisins (FUM) and ochratoxin A (OTA). In addition to these mycotoxins, European samples were analyzed for T-2 toxin (T-2). Due to lab regulations in other parts of the world, the presence of this mycotoxin was not tested for in other regions.
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, and other fodder such as straw, silage and finished feed.
In the more than 4,000 samples analyzed, Afla were present in 25 percent, ZEN in 46 percent, DON in 64 percent, FUM in 56 percent and OTA in 31 percent. Average contamination levels of all samples were 34 ppb for Afla, 251 ppb for ZEN, 1,088 ppb for DON, 1,350 ppb for FUM and 5 ppb for OTA. Compared with data from the previous year, an increase in the occurrence of fusariotoxins (DON, FUM and ZEN) was observed together with a slight decrease in Afla.
