Aflatoxin B1

Friday, November 17, 2017

As a result of the evaluation of the available analysis results of Aflatoxin B1 in maize GMP+ International, together with other accepted scheme holders, has adjusted the risk profile for Aflatoxin B1.

For Canada this means that the risk changes from ‘Medium’ to ‘Low’. This means that maize originating from this country has to be analyzed less frequently, because the risk of the presence of Aflatoxin B1 is to be considered low. 

The changed protocol takes effect on November 20th 2017.


What can you do?

To be able to reclassify countries, it is important for as much GMP+ participants as possible to upload their analysis results to the GMP+ Monitoring database and to share it with the GMP+ community. 

When uploading this information, please make sure that the origin of the maize is entered correctly and that the levels of Aflatoxin detected are entered with the correct unit (mg/kg).

Analyzing monitoring results is a source of inspiration for GMP+ International to emphasize potential risks in its communication and to develop FSP products that make the individual companies and the feed industry as a whole more resilient, to better face the daily challenges involved with supplying safe feed for safe food
