Abstract: The main objectives of the present research were to determination of Ochratoxin A in locally broiler meat sold in markets of Baghdad province by ELISA, effect of ozonated water treatment (0.5ppm/15 min.) on the level of Ochratoxin A in positive samples and finally determination of Ochratoxin A after ozonated water treatment. A total of 50 samples were collected randomly from various markets located in different locations of Baghdad province from each sector Al-Kirkh and Al-Rusafa during November 2017 to March 2018. All meat samples were positive for Ochratoxin A and the result showed that there were a significant differences (P ≤ 0.05) in the residual levels (ppm) of Ochratoxin A between Al-Kirkh and Al-Rusafa before and after ozonated water treatment. The highest Mean ± SE values were recorded in Al-Rusafa (0.648 ± 0.0020), followed by Al-Kirkh (0.636 ± 0.0025) before ozonated water treatment, while the highest Mean ± SE values after ozonated water treatment were recorded in Al-Rusafa (0.346 ± 0.0025), followed by Al-Kirkh (0.332 ± 0.0049). The lowest Mean ± SE values of Ochratoxin A before ozonated water treatment were recorded in Al-Rusafa (0.502 ± 0.0040), followed by Al-Kirkh (0.504 ± 0.0058), while the lowest Mean ± SE values of Ochratoxin A after ozonated water treatment were recorded in Al-Rusafa, followed by Al-Kirkh also at (0.264 ± 0.0040), and (0.266 ± 0.0025) respectively. This research indicated that the poultry meat treated with ozonated water has the advantages methods that it did not affect the colour and texture characteristics of the meat, can be used to eliminate or reduce Ochratoxin A residues at the same time, and can be used in any slaughter house without the need to modify the design of the buildings.
