A total of 200 samples of feedstuffs and mixed feeds used for poultry and pig nutrition in Colombia were analysed for zearalenone using a LC technique with a limit of detection of 20 μg/kg. Samples of grain sorghum, maize, processed soybean, rice meal, cottonseed meal, and poultry and pig feeds, representative of the Colombian production for the 1995-1996 harvest, were taken at feed manufacturing plants located in different cities of the country. Zearalenone was detected in 25 of 45 samples of sorghum, 2 of 33 samples of maize, 7 of 22 samples of rice meal, 9 of 17 samples of cottonseed meal, 11 of 30 samples of poultry feed and 6 of 16 samples of pig feed. Zearalenone was not detected in soybean or other feedstuff s analysed (wheat by- products, cassava meal, palm). Overall levels of zearalenone ranged from 29 to 3956 μg/kg, with a mean value of 436 μg/kg. Only one of the 6 positive samples of pig feed had a zearalenone concentration above 500 μg/kg, which is normally considered as the safe level for pigs.
对哥伦比亚用于家禽和猪营养的 200 种饲料和混合饲料样品进行了分析，采用 LC 技术检测玉米赤霉烯酮，检测限为 20μg/kg。采集了该国不同城市饲料加工厂生产的谷物高粱、玉米、加工大豆、米糠、棉籽粕以及家禽和猪饲料的代表性样品，这些样品是 1995-1996 年收获的哥伦比亚的代表。在 45 份高粱样品中有 25 份、33 份玉米样品中有 2 份、22 份米糠样品中有 7 份、17 份棉籽粕样品中有 9 份、30 份家禽饲料样品中有 11 份、16 份猪饲料样品中有 6 份检测到玉米赤霉烯酮。大豆或其他分析的饲料（小麦副产品、木薯粉、棕榈）中未检测到玉米赤霉烯酮。玉米赤霉烯酮的总体水平在 29 至 3956μg/kg 之间，平均值为 436μg/kg。在 6 份猪饲料阳性样品中只有一份玉米赤霉烯酮浓度超过 500μg/kg，这通常被认为是猪的安全水平。
