Protocol Monitoring Aflatoxin B1 in maize and by-products of maize - Harvest 2024/2025

Based on these criteria, it was decided at the beginning of the 2024 harvest year that all countries should first be classified as Medium, with the exception of 17 low-risk countries.

Changed Risk Profiles:

• Czech Republic - raised from low to medium
• Romania - raised from medium to high

This means that maize originating from 

• Czech Republic must be analyzed more frequently.
• Romania must be analyzed more frequently.

This new risk profile takes effect as from 18 September 2024.

Note:

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 TS1.7 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 TS1.5 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 TS1.5, 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.
