Protocol Monitoring Aflatoxin B1 in maize by-products

Change risk profile for Ukraine

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. 

Changed Risk Profiles:

  • Ukraine -  raised from low to medium

This means that maize originating from

  • Ukraine must be analyzed more

This new risk profile takes effect 17th of April 2023.

Maize originating from a country with High risk must be analyzed more frequently, because the risk of the presence of Aflatoxin B1 is to be considered high.
Consult for more details GMP+ Aflatoxine Protocol TS 1.7 Monitoring - Appendix

We do it together!

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

Be careful

Incorrect analysis results in the database can affect the results of the evaluation and risk classification of the countries.

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).

- Ask your laboratory to report in the correct unit

Ask your laboratory to report the analysis results in the same unit as included in GMP+ BA1/TS 1.5  Specific Feed Safety Limits. For Aflatoxin the correct unit is mg/kg. This helps you when you check the result with the applicable feed safety limits in GMP+ BA1/TS 1.5, but also helps you comply with the requirement of the GMP+ Monitoring database to report the result in this unit.

- If the analysis result is in ppb, you must first convert it to mg/kg.

Why is this important?

Analyzing monitoring results is an important source for GMP+ International in determining potential risks. Also, it helps us developing FSP products that make you and the feed industry as a whole more resilient.
