One of the main actions to counteract mycotoxin issues is to have a clear picture of their prevalence in feedstuffs. For this reason a continuous monitoring in various samples from different geographic areas is a must for helping the customer to identify the mycotoxin risk assessment.
In 2014, 297 samples were collected from our European customers, which included grain, feed, pellets, silage samples, meal and other feedstuff. One thousand five hundred twenty-six analyses were performed by Kemin Customer Lab Service via the immune affinity purification followed by ultra-high performance liquid chromatography separation and UV or fluorescence based quantification
Twenty percent of the samples tested positive for aflatoxins, 67% tested positive for deoxynivalenol, 14% were positive for fumonisins 15% tested positive for ochratoxin A and 30% tested positive for zearalenon.
In this survey, only 19% of the samples were negative for the main mycotoxins investigated and 33% showing only contamination by 1 mycotoxin. This results in a 48% of the samples that proved to be positive for more than one of the main mycotoxin classes. In 11% of the cases, at least 4 different main mycotoxins were identified.
Overall, the presence of deoxynivalenol in combination with zearalenon was most frequently observed (21%) followed by its combination with fumonisin (17%). In feed the most frequent observed combination was deoxynivalenol with aflatoxin followed by its prevalence with fumonisin. For grain, silage and other feedstuff, deoxynivalenol was present with zearalenone more than any other main mycotoxin
