Tissues were collected to survey the actual conditions of tetracycline antibiotics (TCs) residues in slaughtered animals that did not pass inspection at slaughterhouses in Aichi Prefecture, Japan, because of the presence of disease symptoms. Tissues were analyzed by liquid chromatography. Among 271 samples, 49 (18.1%) were positive for oxytetracycline (OTC), 5 (1.8%) for chlortetracycline (CTC), and 5 (1.8%) for doxycycline (DC), respectively. One sample (cattle kidney) was positive for both OTC and DC. However, tetracycline was not detected in any samples. Percentage frequencies of TCs residues were 29.1% (37/127) and 15.2% (22/144) for cattle and hogs, respectively. Kidney samples showed higher incidence of TCs residues and 1.5-7 times higher residual concentrations than liver and miscellaneous samples.
采集组织样本，以调查日本爱知县屠宰场中因出现疾病症状而未通过检验的屠宰动物体内四环素类抗生素（TCs）残留的实际情况。采用液相色谱法对组织进行分析。在271份样本中，土霉素（OTC）阳性的有49份（18.1%），金霉素（CTC）阳性的有5份（1.8%），强力霉素（DC）阳性的有5份（1.8%）。有一份样本（牛肾）OTC和DC均呈阳性。然而，所有样本中均未检测到四环素。牛和猪的TCs残留百分比频率分别为29.1%（37/127）和15.2%（22/144）。肾脏样本中TCs残留的发生率较高，残留浓度比肝脏和其他样本高1.5至7倍。
