61. EWS Mycotoxins harvest cereals 2017


For many years, three OVOCOM members (Apfaca, ARMB and Synagra) are working together towards a targeted monitoring with respect to the presence of mycotoxins in wheat, barley, rye, oats, triticale and spelt. Such monitoring carried out as quickly as possible after harvest (early warning), allows us to estimate the “degree of contamination” of mycotoxins in cereals.

 

The final report has been published last week. No less than 353 samples were analyzed: 60% of wheat samples, 30% of barley samples. Most of the samples are of Belgian or French origin. The results of the 2017 harvest are generally better than in 2016. In 40% of the samples, 1 or more mycotoxins have been detected (2016: 64%; 2015: 34%).

The results included in the final report are presented here below:

 

DON

 

  • 90% of the results present a value that is below the detection limit of 300 ppb;
  • No result exceeds the value of 1.250 ppb for DON in unprocessed cereals (food);
  • No result exceeds the value of 8.000 ppb for DON in unprocessed cereals (cereal products – feed).

 

Zearalenone (ZEA)

 

  • The target value of cereals (and cereal products) is 2.000 ppb (food: 100 ppb);
  • 99% of the results have a value that is below the detection limit;
  • 1% of the samples in which ZEA was detected concerns wheat and barley;
  • The maximum value found is 98 ppb (wheat of Flemish origin destined for feed).

 

T-2 and HT-2

 

  • The indicative levels for cereals and cereal products intended for feed and compound feed is 500 ppb, for barley (food), this amounts to 200 ppb;
  • The maximum detected value is 1.193 ppb (barley of Belgian origin and destined for feed).

 

Aflatoxine B1, Fumonisines B1 et Fumonisines B2

 

  • All values are below the detection limit.

 

The following conclusion may be made:The results of the 2017 harvest are generally better than the results of the 2016 harvest and are in line with the results of the 2015 harvest”.

 

It is also very important to bear in mind the possible increase of the mycotoxin levels during storage. Indeed, the above mentioned levels are only an indication of the presence of mycotoxins in the field at the time of harvest. Therefore, one must remain vigilant!
