Histamine concentrations were determined in semi-moist and moist cat foods which listed fish or fish solubles as one of the ingredients using the AOAC fluorometic method and a TLC procedure. Percent recovery was 73% for the AOAC and 96% for the TLC procedure, although the coefficient of variation was lower for AOAC procedure. Moist cat foods contained an average of 11 ppm histamine while semi-moist cat foods had 23 ppm histamine. High histamine content of semi-moist cat food was probably due to condensed fish solubles even though it was not one of the major ingredients. The maximum amount of histamine observed was 88.8 ppm in a semi-moist cat food sample while the minimum was 3.8 ppm in a moist cat food sample. Results from both procedure compared well.
使用美国官方分析化学家协会（AOAC）荧光法和薄层色谱法（TLC），测定了将鱼或鱼溶浆列为成分之一的半湿和湿猫粮中的组胺浓度。AOAC法的回收率为73%，TLC法为96%，不过AOAC法的变异系数更低。湿猫粮中组胺的平均含量为11 ppm，而半湿猫粮中组胺含量为23 ppm。半湿猫粮中组胺含量高可能是由于浓缩鱼溶浆，尽管它并非主要成分之一。在一份半湿猫粮样品中观察到的组胺最大含量为88.8 ppm，而在一份湿猫粮样品中最低含量为3.8 ppm。两种方法的结果比较吻合。
