The levels of zearalenone were investigated in total 99 various commerical feed mixtures and feed ingredients by using HPLC. The sensitivity of the method was found as 1 µg/kg. Samples were collected in the periods of January February and April May from Konya, Adana, Bursa regions. In the first period, total 65 samples which are 19 feeds and 46 feed- stuffs were analysed. Zearalenone was determined in 6 samples of the feeds and 15 samples of the feedstuffs. The avarage level of zearalenone was calculated as 3.66mu*g / k * g in whole samples. In the second period, total 34 samples which are 11 feeds and 23 feed- stuffs were analysed. Zearalenone was determined in 6 samples of the feeds and 8 samples of the feedstuffs. The average level of zearalenone was calculated as 5.46mu*g / k * g in whole samples. In both periods, the percentage of the samples included zearalenon was average 33 % and the mean zearalenone level was determined as 4.31 µg/kg feed. The samples contained about 10 mu*g / k * g zearalenone may cause hipercostrogenism in pigs. Same effects may be seen in the other animals when these feedstuffs fed for a long periods.
