Abstract

Feedstuffs and mixed feeds used for poultry and pig nutrition in Colombia were analyzed for aflatoxins by using a liquid chromatographic technique with a limit of detection of 1 microgram/kg for each aflatoxin (B1, B2, G1, and G2). Samples of grain sorghum, maize, processed soybean, rice meal, cottonseed meal, and poultry and pig feeds, representative of Colombian production for the 1995-1996 harvest, were taken from feed-manufacturing plants in various cities. Aflatoxins were detected in 11 of 45 samples of sorghum, 4 of 33 samples of maize, 8 of 22 samples of rice meal, 15 of 17 samples of cottonseed meal, 1 of 12 samples of other feedstuffs, 12 of 30 samples of poultry feed, and 7 of 16 samples of pig feed. Aflatoxins were not detected in soybean. Only 9 of 58 positive samples contained total aflatoxin levels exceeding maximum tolerable limits in Colombia.

摘要

采用液相色谱技术对哥伦比亚用于家禽和猪营养的饲料及混合饲料进行黄曲霉毒素分析，每种黄曲霉毒素（B1、B2、G1和G2）的检测限为1微克/千克。从各城市的饲料生产厂采集了代表1995 - 1996年收获季哥伦比亚产量的高粱、玉米、加工大豆、米粉、棉籽粕以及家禽和猪饲料样本。在45份高粱样本中的11份、33份玉米样本中的4份、22份米粉样本中的8份、17份棉籽粕样本中的15份、12份其他饲料样本中的1份、30份家禽饲料样本中的12份以及16份猪饲料样本中的7份检测到了黄曲霉毒素。大豆样本中未检测到黄曲霉毒素。在58份阳性样本中，只有9份的总黄曲霉毒素含量超过了哥伦比亚的最大耐受限量。
