چکیده

Deoxynivalenol (DON) is a toxic fungal metabolite found on wheat, maize and barley. We previously reported a significant association between the amount of DON in a single 24 h urine sample and the average cereal intake over 7 d for 300 UK adults. In this more detailed analysis of the data, food diary information (n 255) for the day of urine collection (model I), the previous 24 h period (model II) and the day of urine collection plus the previous 24 h combined (model III) were further examined to assess whether the recent intake of cereal correlated more strongly with urinary DON, compared with the longer-term assessment of usual cereal intake from 7 d food diaries (model IV). DON was detected in 254/255 (99.6 %) urine samples (mean 12.0 microg/d; range not detected-66 microg/d). For all the models, total cereal intake was positively associated with urinary DON (P < 0.001) in each model. The goodness of fit (adjusted R2 value) was used to assess how well each model explained the variation in urinary DON. Model I provided a better goodness of fit (adjusted R2 0.22) than model IV (adjusted R2 0.19), whereas model III provided the best fit (adjusted R2 0.27). These data suggest that the inter-individual variation in urinary DON was somewhat better explained by recent cereal intake compared with usual cereal intake assessed over 7 d.

Urinary Deoxynivalenol Is Correlated with Cereal Intake in Individuals from the United Kingdom

BACKGROUND Deoxynivalenol (DON) is a toxic fungal metabolite that frequently contaminates cereal crops. DON is toxic to animals, but the effects on humans are poorly understood, in part because exposure estimates are of limited precision. OBJECTIVES In this study we used the U.K. adult National Diet and Nutrition Survey to compare 24-hr urinary DON excretion with cereal intake. METHODS One ...

Deoxynivalenol Biomarkers in the Urine of UK Vegetarians

Deoxynivalenol (DON) is produced by Fusarium graminearum and is one of the most commonly occurring trichothecenes. Vegetarians are alleged to be a high-risk group for DON exposure due to high intakes of cereals susceptible to the growth of the mycotoxin. This study provides the levels of DON and de-epoxi Deoxynivalenol (DOM-1) in urine analysed by liquid chromatography-mass spectrometry (LC-MS)...

Assessment of Urinary Deoxynivalenol Biomarkers in UK Children and Adolescents

Deoxynivalenol (DON), the mycotoxin produced mainly by Fusarium graminearum and found in contaminated cereal-based foodstuff, has been consistently detected in body fluids in adults. Available data in children and adolescents are scarce. This study assessed urinary DON concentrations in children aged 3-9 years (n = 40) and adolescents aged 10-17 years (n = 39) in the UK. Morning urine samples w...

Occurrence of Deoxynivalenol in Foods for Human Consumption from Tehran, Iran

AbstractThe occurrence of deoxynivalenol (DON) in retail foods in Tehran (Iran) was determined using high-performance liquid chromatography technique and immunoaffinity column as the clean-up step. A method was validated for analysis of DON in rice, bread, puffed corn snack and wheat flour. The average recoveries and precision (RSD) for DON in different foods ranged 84.2-93.1% and 2.9-12.0%, re...
