摘要：
The incidence of fungal contamination in 91 samples of feed and raw materials used for animal feeding in Spain has been studied. Sample analysis was accomplished in a new culture medium to which a beta-cyclodextrin had been added, and a comparison with other more usual culture media was performed. Ochratoxin A (OTA) and zearalenone (ZEA) contamination of all the samples was evaluated by RP-HPLC with fluorescence detection. The fungal genera found, such as Penicillium and Fusarium, included mycotoxigenic strains as OTA and ZEA (33.3 and 26.4% incidence respectively). One sample of corn and another of cotton seed were contaminated with levels of OTA above the 5 and/or 10 mug kg(-1) recommended by the legislation of several European countries, whereas none of the samples contaminated with ZEA surpassed the legislation limits suggested by the official agencies.
