Aflatoxin B1 in corn silage and its probability passing in milk [Misir silajinda aflatoksin B1 varliǧinin ve süte geçme durumunun araştirilmasi]

The aim of this study was undertaken to determine the levels of aflatoxin b1 contamination in corn silage samples and aflatoxin m1 in milk samples collected from cow dairy farms in pasinler (erzurum,turkey) region. average amount of aflatoxin b1 in feed and aflatoxin m1 in milk were found 36i.i2±94.76 ppt and 3.85±3.71 ppt respectively. it was found that,1.07% aflatoxin b1 passed to milk as a aflatoxin m1. aflatoxin m1 was not found in 6 samples (8.33%) of the milk. aflatoxin m1 was found in 66 samples (9i.67%) of the examined milk samples. none of the samples had aflatoxin m1 greater than the maximum tolerance limit accepted by turkish food codex. aflatoxin b1 was not found in 3 samples (4.i6%) of the silage. aflatoxin b1 was found in 69 samples (95.84%) of the examined silage samples. none of the samples had aflatoxin b1 greater than the maximum tolerance limit accepted by turkish standard. in the statistical analysis,there was positive correlation (p<0.0i) between aflatoxin m1 in the silage samples and aflatoxin m1 in the examined milk samples. to achieve minimum levels of aflatoksin m1 in milk and milk products,modern production techniques should be employed,the animal feed storage conditions should be well- maintained and inspected,milk producers should be well-informed. food and feed items should be analyzed for the presence of aflatoxin at every level the consumption of the ones that contain aflatoxin in amounts higher than the tolerable limits valid in our country should not be permitted. in order to prevent mould growth,and consequently,forming of aflatoxin on animal feed and food,effective,economical and applicable chemical materials should be researched and field investigations should be conducted for confirmation of the applications.
