Perchlorate has been considered a potential threat to human health, especially to developing infants and children due to its ability to inhibit iodide uptake by the sodium iodide symporter (NIS) of the thyroid. Although the U.S. has been the prime focus of perchlorate contamination, at least some of the similar sources of perchlorate exist across the world, and it has been detected in many types of foods and beverages worldwide. We present here perchlorate data from cow's milk samples from Japan (mean 9.4 +/-2.7 microg/L, n = 54), which are higher on average than those found in U.S. dairy milk samples reported by a 2004 Food and Drug Administration (FDA) study (5.9+/-1.8 microg/L, n= 104).
高氯酸盐被认为对人类健康存在潜在威胁，尤其是对发育中的婴幼儿，因为它能够抑制甲状腺钠碘转运体（NIS）对碘的摄取。尽管美国一直是高氯酸盐污染的主要关注对象，但世界各地至少存在一些类似的高氯酸盐来源，并且在全球多种食品和饮料中都检测到了高氯酸盐。我们在此展示来自日本牛奶样本的高氯酸盐数据（均值为9.4±2.7微克/升，n = 54），该数据平均高于2004年美国食品药品监督管理局（FDA）研究报告的美国牛奶样本中的数据（5.9±1.8微克/升，n = 104）。
