Protocol Monitoring Aflatoxin B1

Aflatoxin B1 in maize(-products): Change in Risk Profile for several countries.

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. Because of the forthcoming new maize harvest, the classification of countries also takes into account information about growing and harvesting conditions. In addition, consideration has been given to countries where a possible mix with old (2019) harvest from high-/medium risk countries could pose a risk to feed safety. Based on these criteria, it was decided at the beginning of the 2020 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
  • Hungary -  raised from low to medium
  • Spain -  raised from low to medium
  • Ukraine -  raised from low to medium

This means that maize originating from

  • Czech Republic must be analyzed more frequently
  • Hungary must be analyzed more frequently
  • Spain must be analyzed more frequently
  • Ukraine must be analyzed more frequently

This new risk profile takes effect 30th of September 2020.

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.

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 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, but also helps you comply with the requirement of the GMP+ Monitoring database to report the result in this unit.

Other changes in the protocol

  • The exemption for positive release for direct delivery by truck from countries with high and medium risk is deleted. The exemption is still possible only in case of direct delivery with truck from a Medium risk country under strict conditions (See article and 2.3.12)
  • New Sampling method in case of ship to ship transshipment is added. (see articles and
  • The requirement for laboratories has been updated

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.
