Background and aims: Ochratoxin A (OTA) is mycotoxins that possess a risk to human health due to its nephrotoxic, immunotoxic, mutagenic, teratogenic and carcinogenic effects. This study was undertaken to determine the presence and levels of ochratoxin A in different types of bread consumed in Shahrekord. Methods: In this descriptive study, eighty six samples of different types of bread purchased from March to December 2011 from retail bakeshops in Shahrekord was surveyed for the presence of ochratoxin A (OTA) using ELISA method. Results: Ochratoxin A was detected in 45 out of the 86 bread samples (52.3%). Levels of OTA in positive samples ranged between 0.19 and 10.37 ng/g and the average contamination of all positive samples was 2.61± 1.47 ng/g. Fifteen of the positive samples exceed the maximum level of 5 ng/g set by European regulations for OTA in cereals and bread. Seasonal evaluation of the data did not indicate a significant difference in contamination levels. Conclusion: It is therefore important to monitor the level of OTA in cereals especially wheat and to devise mechanisms to improve their quality in such a way that reduce OTA contamination of bread.
