Mycotoxins are the biggest challenge for animal feed producers and therefore, regular monitoring of mycotoxins is necessary.

The aim of the present study was to screen corn samples for mycotoxins, received from different countries and regions of the world, between September 2019 and February 2020.

The corn samples were collected from North and South America (Mexico, Chile, Peru, Colombia, Argentina, Brazil) Asia (India, Iraq, Thailand, Vietnam, Taiwan) and Europe (Serbia, Spain, France, Italy, Bosnia & Herzegovina, Russia, Belarus, and Croatia).

These corn samples were analyzed by LC-MS/MS triple quad (Agilent 6460 series) based multi-mycotoxin method for quantification of all mycotoxins present (Aflatoxin B1 (AFB1), B2, G1 and G2, Ochratoxin A (OTA), Zearalenone (ZON), Deoxynivalenol (DON), Fumonisin B1 and B2 (FB1 & FB2), T-2 & HT-2 toxins) that are regulated in the EU in feed by EU Directive 2002/32/EC, 2006/576/EC and 2013/165/EU.

RESULTS

  • Mycotoxins detected in the corn samples in each country in 2019 and the overall conclusions based on the integrated global data sets for this year.
  • Comparisons of the mycotoxins detected in 2018 v 2019.
  • Effects of detected mycotoxins on animals.
  • Overall Conclusions.

MYCOTOXINS DETECTED in corn per country in 2019

CHILE

In 2019, 93% of the corn samples received from Chile were contaminated with one or more mycotoxins (Fig 1).

Higher and co-occurrence of Fumonisins (93% of the samples) followed by DON in 20% and ZON in 7% samples was recorded (Table 1).
