Aflatoxin M1 (AFM1) results primarily from the conversion of Aflatoxin B1 (AFB1) that is metabolized by enzymes found primarily in the liver. (AFB1, M1) that may lead to severe problems in human health were analyzed in sixty samples of each chicken organs (liver, gizzard and heart) that were collected randomly during March to June 2014 from different retail markets. The results revealed that 45% of chicken liver, 32% gizzard and 25% heart samples were found contaminated with AFB1. Furthermore, 33% chicken liver, 25% gizzard and 22% heart samples were found contaminated with AFM1 and the maximum mean level 2.24 ng/g was found in the chicken liver. Ozonated water was used for detoxification of mentioned toxins in positive samples. The positive sample with maximum concentration was treated with ozonated water dose 20ppm at different time 0.5, 1.0, 1.5, 2.0, 2.5 min. The results show the effectiveness of ozonated water for removal or elimination of mentioned toxins from studying chicken organs since our treatment full succeeded in the removal of mentioned toxins in gizzard and heart samples at 2.5 min. On the other hand AFM1 was decreased from 3.73 to 0.69 ng/g at 2.5 min. It is worthy to report that effective of ozonated water for removal or elimination of AFM1 from liver, gizzard and heart samples to avoid the hazard of AFM1.
