Incidence of aflatoxin and ochratoxin in some poultry ration with trial for control in Beni-Suef Governorate.

: A total of 60 samples (30 poultry feed and 30 chicken liver samples) were collected randomly from some farms and localities in Beni-Suef Governorate in summer and winter seasons for monitoring my-cotoxin contamination condition in such farms. Samples were examined for aflatoxin and ochratoxin levels. All samples (poultry feed and chicken liver samples) were found contaminated with both mycotoxins. Concerning , poultry feed samples in summer, aflatoxin levels ranged from 1.10 to 65 ppb with mean of 8.79±4.11, one sample (6.66%) exceeded the permissible limit (20 ppb); While, ochratoxin levels ranged from 3.50 to 9.90 ppb with mean of 5.51±0.52, eight samples (53.33%) exceeded the permissible limit (5 ppb). In winter, aflatoxin levels ranged from 0.15 to 7.70 ppb with mean of 3.01±0.93, all samples were within the permissible limit (20 ppb); while, ochratoxin levels ranged from 2.50 to 11.90 ppb with mean of 4.55±0.70, four samples (26.66%) exceeded the permissible limit (5 ppb). Chicken liver samples were found contaminated with aflatoxin levels ranged from 0.51 to 6.52 ppb with mean of 2.15±0.72, all these levels were within FDA permissible limit (20 ppb); nine samples (30%) exceeded FAO permissible limits (4 ppb). While, ochratoxin levels ranged from 1.90 to 5.40 ppb with mean of 2.55±0.32, three samples
