Abstract :The aim of this study was to investigate the occurrence and levels of ochratoxin A insert ignore into journalissuearticles values(OTA); in coffee insert ignore into journalissuearticles values(roasted and instant);, dried grapes and  grape pekmez samples consumed in Burdur city markets. During 2015, a total of 86 samples including 43 coffee insert ignore into journalissuearticles values(30 instant coffee and 13 roasted coffee);, 17 dried grapes and 26 grape pekmez were randomly collected from different markets of Burdur. The occurrence and contamination levels of OTA in the samples were investigated by the competitive enzyme-linked immunoabsorbent assay insert ignore into journalissuearticles values(ELISA); method. OTA was detected in 24 insert ignore into journalissuearticles values(55 %); coffee samples insert ignore into journalissuearticles values(13 roasted coffee and 11 instant coffee samples); and in 1 insert ignore into journalissuearticles values(3 %); grape pekmez samples. The range  OTA levels were 8.34 and 22.54 μg/kg in coffee samples and 20.48 μg/kg in one grape pekmez sample, respectively. The highest recorded OTA concentration was 22.54 μg/kg in instant coffee. Furthermore, 13 roasted coffee, 11 instant coffee and 1 grape pekmez samples were contaminated at levels above the Turkish legal limits of 5 μg/kg,10 μg/kg and 2 μg/kg, respectively. In contrast, OTA was not detected in all dried grape samples. It is concluded that the occurrence of OTA, coffee samples, in particular may be considered as a possible hazard for public health.
