“…Ainsi, le choix du cultivar, le type de travail du sol, le pre´ce´dent cultural sont autant de facteurs qui peuvent influencer le contenu en DON des re´coltes (Dill-Macky et Jones 2000; Schaafsma et al 2001;Choo et al 2004;Edwards 2004;Fernandez et al 2007;Pageau et al 2008). Afin de pre´venir la croissance des champignons et le de´veloppement des toxines, le grain devrait eˆtre re´colte´lorsque son taux d'humidite´est le moins e´leveṕ ossible (Schro¨der 2004). D'apre`s nos re´sultats, le total des pre´cipitations semble avoir peu d'effet sur le contenu en DON.…”

“…At harvest and storage of cereals, spore containing material and humidity combined with temperature are the key factors affecting trichothecene formation. Minimising or avoiding spore containing materials, grain cleaning at harvest and drying at low temperatures will allow storage of cereals for more than 12 months without increasing trichothecene levels (Schrödter, 2004). Storage conditions play an important role in mycotoxin control, since they will influence overall fungal development.…”

A study was conducted at Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry to explore the quantitative changes in type B trichothecenes: deoxynivalenol (DON), 3-acelyt-deoxynivalenl (3-ADON) and 15-acetyl-deoxynivalenol (15-ADON), in spring wheat whole-grain flour as influenced by storage period and temperature. Samples with different concentrations of DON and its metabolites were selected and stored in two controlled climate chambers at different temperatures (18°C and 28°C) at the same ambient air humidity (~80%). The initial concentration ranged from 1246 to 4581 µg kg-1 for DON, from 440 to 820 µg kg-1 for 3-ADON and from 88 to 141 µg kg-1 for 15-ADON. The samples were analysed before the storage experiment and then after 4 and 8 weeks of storage. The findings of the DON retention showed no significant differences between the storage periods and temperatures; however, it was found that over time the concentrations of DON in the samples decreased. There were found significant differences (P < 0.05) in 3-ADON concentrations between storage periods and temperatures. Over time, 3-ADON concentrations decreased in the samples. Statistically significant increases in 15-ADON concentrations were identified over this period. Within 60 days of storage, the concentrations of DON decreased by 16% and 33%, 3-ADON-by 60% and 100%, and those of 15-ADON increased by 63% and 96% compared to the initial levels, depending on the combination of the experimental factors. The results of this study led to the conclusion that storage of spring wheat flour for several months at 80% relative humidity, at 18°C and 28°C temperatures did not have significant influence on the retention level of DON. However, the levels of DON derivative 3-ADON significantly decreased and the concentrations of 15-ADON significantly (almost twice) increased during flour storage and aging.

“…The present results indicated that these cranes were potentially exposed to mycotoxins during the entire wintering period. Seasonal weather patterns, preharvest, harvest, and storage conditions can place agricultural crops at risk for mycotoxin contamination (Schrödter, 2004;Georgiadou et al, 2012;Torres et al, 2014). Some studies have shown that rice not only contains considerable amounts of fungi but is also contaminated with mycotoxins (Park et al, 2005;Nguyen et al, 2007;Bansal et al, 2011;Qiu and Shi, 2014).…”

Abstract:A survey was conducted to determine whether mycotoxins were present in the foods consumed by red-crowned cranes (Grus japonensis) in the Yancheng Biosphere Reserve, China. Collected in the reserve's core, buffer, and experimental zones during overwintering periods of 2013 to 2015, a total of 113 food samples were analyzed for aflatoxin B 1 , deoxynivalenol, zearalenone, T-2 toxin, and ochratoxin A using high performance liquid chromatography (HPLC). The contamination incidences vary among different zones and the mycotoxins levels of different food samples also presented disparity. Average mycotoxin concentration from rice grain was greater than that from other food types. Among mycotoxin-positive samples, 59.3% were simultaneously contaminated with more than one toxin. This study demonstrated for the first time that red-crowned cranes were exposed to mycotoxins in the Yancheng Biosphere Reserve and suggested that artificial wetlands could not be considered good habitats for the birds in this reserve, especially rice fields.
