Monitoring- Report 2017 Futtermittel Monitoring- Report 2019 Feed On 1 July 2019, the mycotoxins aflatoxin B1, DON and ZEA were included in the QS control plan for tubers and roots, their pro- ducts and by-products. To that end, QS defined guidance val- ues for the parameters DON and ZEA (see table on Page 1). The monitoring is carried out as a harvest screening at the be- ginning of the sugar beet campaign: During the first two weeks of the campaign, on at least three days, a representative sample of the sugar beet pulp is taken and analysed for mycotoxins. This is carried out for every loca- tion. The analysis results for these samples must be uploaded in the QS database within three weeks after the start of the campaign. If the QS guidance values are exceeded: QS and the customers of the goods must be informed, and the analysed value must be communicated. For feed deliveries to livestock owners for direct feeding, a recommendation for use must be made (percentage use limit for the ration). If the harvest screening reveals a contamination of the sugar beet pulp, the monitoring is extended to the whole campaign. ■ Mycotoxin analysis for the 2019/2020 sugar beet campaign (continued from Page 1) Regular revaluation of contaminants Are there mycotoxins that are transmitted from feed to humans via animals? If agricultural products containing mycotoxins are fed to ani- mals, the mycotoxins may be passed into foodstuffs of ani- mal origin such as meat, milk or eggs. This transfer is described, for example, in the case of aflatoxins, where a carry-over from the feed to milk takes place. However, in meat and eggs, aflatoxins only pass in small amounts. What role do combined effects* play in mycotoxins? Efforts are currently being made to pay greater attention to the aspect of the combined effects in the health assessment of contaminants, including mycotoxins. The corresponding guidelines are currently being developed. The combined ef- fects of certain mycotoxins, such as aflatoxins (sum of the four aflatoxins B1, B2, G1, G2) and ergot alkaloids (sum of 12 different ergot alkaloids), are already being taken into account today. * Note from QS: The interaction of several substances increases their individual effect on an organism (synergistic combined effect). How often are contaminants re-evaluated? For contaminants, a periodic revaluation at a certain point in time is not required by law. However, the availability of new data can lead to a re-evaluation of the health assess- ment. For example, the mycotoxin ochratoxin A is being cur- rently re-evaluated by the European Food Safety Authority (EFSA) and the previous health-based guidance value is being reviewed in the light of new toxicological studies. The mycotoxin zearalenone (ZEA) was recently detected in sugar beet pulp. Is a revaluation planned here as well? The first detection of ZEA in sugar beet took place in the United States more than 20 years ago. In recent years, ZEA has also been repeatedly reported in sugar beets in Europe. This means that sugar beet is not a "new" host plant, but should be taken more into account than in the past in the self-monitoring and, if applicable, in official controls. ■ DON, ZEA, OTA, aflatoxin B1 and ergot are included in the control plans of the QS scheme. With the exception of ergot, the mycotoxins are analysed by QS approved laboratories. The results are entered into the QS data- base. Ergot is initially visually inspected by the company itself during the incoming goods inspection.

This is because the sclerotia show different levels of the individual ergot alkaloids. For instance, even in a sample with a low ergot content, there may be a relatively high content of ergot alkaloids and vice versa. The working group "Carry over unerwünschter Stoffe in Futtermitteln" (only available in German) at the German Federal Mi- nistry of Food and Agriculture (BMEL), recently published a statement with orientation values on ergot alkaloid contents. These have been defined for every individual animal species, as there are clear diffe- rences in the species-specific sensitivity to ergot. The working group is composed by experts from the German Federal Institute for Risk Assessment (BfR), the Friedrich-Loeffler-Institut, the Max Rubner-Institut, the Julius Kühn-Institut and other scientific institutions. A conversation with experts from BfR In order to protect the consumer's health, it is essential to limit the content of contaminants in feed and food to accept- able levels from a toxicological point of view, or to minimise them as much as technically possible. For this reason, the German Federal Institute for Risk Assessment (BfR) assesses the health risk posed by contaminants and develops recom- mendations. A closer look at current figures and data is the basis for an always reliable health assessment.
