Resumo: Defective coffee beans may contain toxins such as ochratoxin A (OTA) and other compoundswhich affect health. In the present work two coffee producing regions were studied: Cerrado in Minas Gerais and Sorocabana in São Paulo State, with the objective of verifying the presence of ochratoxigenic fungi and OTA in the main defective coffee beans. Coffee samples were surface disinfected and plated directly onto Dichloran Glycerol Agar. Fungal specieswere isolated and identified. The coffee sampleswere analyzed for OTA and quantified by High Performance Liquid Chromatography (HPLC) equipment. Aspergilluswesterdijkiae and Aspergillus section Nigri were found in both regions, while Aspergillus carbonarius only in Cerrado-MG, especially in defective coffee beans. The sour and black defective beans had the highest OTA concentration being 11.3 μg/kg and 25.7 μg/kg, respectively. In the defective green (immature) beans, although having the highest proportion (38%), the presence of ochratoxigenic fungi and OTA was low. © 2014 Elsevier Ltd. All rights reserved.
