Monitoring of fusarium toxins in cereals and feed-stuffs from thuringia (1998 - 2001)

From 1998 to 2001 a total of about 1172 conventionally and organically produced samples of wheat, rye, barley and triticale were examined for the presence of deoxynivalenol (DON) and zearalenone (ZON). Furthermore, feedstuffs for pigs were included in the monitoring of Fusarium toxins. DON and ZON analyses were performed using ELISA or HPLC. The incidences and levels of toxins varied from year to year. Overall contamination levels were highest in wheat and triticale, followed by rye and barley. The highest DON contaminations were found in 1998. The probes of the years 1999-2001 showed lower incidences of Fusarium toxins. The second examined mycotoxin ZON was detected at lower levels in cereals. Similar results were observed in the monitoring of feedstuffs.
