Intake of ochratoxin A and deoxynivalenol through beer consumption in Belgium.
Food Addit Contam
August 2007
Estimations of ochratoxin A (OTA) and 4-deoxynivalenol (DON) exposure of the Belgian population through beer consumption were made using the results of the recent Belgian food survey and the compiled data set of OTA and DON levels in conventionally and organically produced beers in 2003-05. For the consumers of organic beers, the daily intake of OTA was 0.86 (in 2003), 1.

Assuming no further change in contaminant levels during cereal processing and during the preparation of foodstuffs, conservative intakes are estimated for the consumers of cereal-based products such as flour, bread, breakfast cereals, dough and pastry. The results show that for the consumer of organic foodstuffs, estimated daily intakes are 0.

- - In 2002, Puccinia xanthii Schwein was identified on hunter burr plants in Debrecen, Hungary, showing that the disease impacts leaves, stems, and petioles, particularly influenced by population density of the weed.
- - Higher densities of hunter burr (20 plants/m) resulted in a significant infection rate of 70% by September, with early symptoms starting in late July for this group, compared to early August for lower densities (6 plants/m).
- - Pathogenicity tests indicated that the pathogen rapidly infects healthy plants, with symptoms appearing within four days of inoculation, confirming that the teliospores from both field and greenhouse were morphologically identical.
