Crambe (Crambe Hispanica Subsp. Abyssinica) Grains Mycobiota and Natural Occurrence of Aflatoxins, Ochratoxin A, Fumonisin B1 and Zearalenone.

Fungal overgrowth may lead to mycotoxins production and nutritional properties decrease of the grains. The aim of this study was to analyze the occurrence of fungi and mycotoxins according to pre-harvesting management. Fungal concentration was higher than that recommended by international regulations, suggesting that management in pre-harvesting stages of crambe grains production may expose the animals that will feed on these grains to the risk of contamination by fungal toxins.

Monitoring of grains during pre-harvest and postharvest stages is important to avoid undesirable fungal overgrowth and mycotoxins productions. During post-harvest stage, the inspection of storage conditions is crucial at this stage, as the same important, may be impossible disregards geographic localization of cultures and production systems. Contamination of seeds by mycotoxins producing fungi is mainly associated to the relation between the plant and its endophytic mycobiota and to other biological interactions.

The importance of climatic and meteorological assessment during cultivation to assess contamination risks and create predictive models to control the incidence of toxigenic fungi and mycotoxins12 and the delay of harvesting of oleaginous species, such as peanut may cause
increase of A. flavus contamination of pods, production of aflatoxin G1 (AFG1), aflatoxins G2 (AFG2) and drying environment may cause higher incidence of A. flavus in the seeds.

The relevance of weather forecast and climate knowledge during harvest and point out the importance of drawing sampling plans and predictive models to assess the risk of contamination by fungi in cultivated areas
