对84条蓝鳍金枪鱼（Thunnus Thynnus）进行了分析，以了解地理上遥远的粮农组织（联合国粮食及农业组织）捕捞区生物胺发生率的概况：西印度洋（51），地中海（37），中西太平洋（71）和中东部大西洋（34）。尸胺和腐胺显着积累在一些样品中，而组胺和亚精胺是不太丰富，但更频繁地存在。所有组的组胺浓度都很低，FAO 51样本中的组胺浓度最高（第25 - 75百分位数的中位数= 9.3，4.4-13.4 mg kg（-1））。来自FAO 51、37和71号的金枪鱼中完全不存在尸胺，而大西洋样本显示其明显存在（第25 - 75百分位数的中位数= 34.7，17.6-66.9毫克/千克）。腐胺通常出现在尸胺之后，但其水平仍然很低：FAO 51和37没有显示任何腐胺的存在，而FAO 71的浓度略有升高（第25 - 75百分位数的中位数= 6.1，0-43.3 mg kg（-1））。FAO组间精胺水平无显著差异。结果表明，既定的捕获，捕获后和存储的做法用于蓝鳍金枪鱼确保良好的质量。在调查的样品中未检测到有害成分，不存在健康风险。报告的生物胺质量和数量的差异是由粮农组织地区之间的环境条件和个体差异引起的。
The total of 84 Bluefin tunas (Thunnus Thynnus) were analysed in order to obtain an overview of biogenic amines incidences in geographically distant capture fishing FAO (Food and Agriculture Organization of the United Nations) zones: Western Indian Ocean (51), Mediterranean Sea (37), Western Central Pacific Ocean (71) and Eastern Central Atlantic Ocean (34). Cadaverine and putrescine were remarkably accumulated in some samples, whereas histamine and spermidine were less abundant, but more frequently present. Histamine concentration was very low in all groups, having the highest value in samples from FAO 51 (median with 25th-75th percentile = 9.3, 4.4-13.4 mg kg(-1)). Cadaverine was completely absent from tunas deriving from FAOs 51, 37 and 71, while Atlantic Ocean samples demonstrated its noticeable presence (median with 25th-75th percentile = 34.7, 17.6-66.9 mg kg(-1)). Putrescine generally followed the cadaverine occurrence, but its levels remained very low: FAO 51 and 37 did not reveal any presence, while in FAO 71 slightly elevated concentrations appeared (median with 25th-75th percentile = 6.1, 0-43.3 mg kg(-1)). There were no significant differences in spermine levels between FAO groups. The results indicate that the established capture, post-capture and storage practices used for Bluefin tunas ensure good quality. A hazardous content could not be detected in the investigated samples and a health risk does not exist. Reported differences in biogenic amine quality and quantity are provoked by environmental conditions and individual variation between FAO areas.
