The contamination of feed with the Fusarium toxin deoxynivalenol (DON) decreases feed intake and daily gain of pigs but also affects their immune response (Étienne and Waché, 2008). Consequently, they could be predisposed to infectious disease. An experiment was conducted to evaluate the effects of a brief contamination of post-weaning feed with DON on performance and health condition during po...

The trichothecene mycotoxin deoxynivalenol (DON) is a well known and common contaminant in food and feed. Acetylated derivatives and other biosynthetic precursors can occur together with the main toxin. A key biosynthetic step towards DON involves an oxidation of the 8-OH group of 7,8-dihydroxycalonectrin. Since analytical standards for the intermediates are not available and these intermediate...

In 1998, a typhoon struck before rice harvesting in Japan, and the unpolished rice was found to be stained brown. Samples were collected and analyzed for the presence of trichothecenes using GC/MS. The mycotoxins deoxynivalenol (DON), fusarenon-X (Fus.-X) and nivalenol (NIV) were detected and confirmed with GC/MS. The quantity of trichothecenes was determined using GC-ECD. To our knowledge, thi...

Each year, mycotoxins cause economic losses of several billion US dollars worldwide. Consequently, methods must be developed, for producers and cereal manufacturers, to detect these toxins and to comply with regulations. Chromatographic reference methods are time consuming and costly. Thus, alternative methods such as infrared spectroscopy are being increasingly developed to provide simple, rap...

BACKGROUND AND AIMS Deoxynivalenol (DON) is a Fusarium derived mycotoxin, often occurring on cereals used for human and animal nutrition. The intestine, as prominent barrier for nutritional toxins, has to handle the mycotoxin from the mucosa protected luminal side (apical exposure), as well as already absorbed toxin, reaching the cells from basolateral side via the blood stream. In the present ...
