Abstract

Crambe grains are a new feed with high concentrations of proteins and fibers. As there is no control during the pre-harvesting or post-harvesting stages of production other grains, crambe may be contaminated by fungi. 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 (3.4×106 to 1.3×104 CFU.g-1), 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. More studies are required about quality of crambe grains, because may be strongly affected by the exposition to variable environmental conditions. But, considering low mycotoxin incidence and levels founded, the crambe proves to be a safe food to be exploited for animal nutrition.
