研究指出,，吃錯魚會使人暴露于高濃度汞的風(fēng)險加大,。研究還介紹了不同魚種對應(yīng)的汞含量，以及建議的攝入量,。
消費(fèi)者報告建議,，孕婦應(yīng)避免食用任何金槍魚，包含金槍魚罐頭,；不再建議育齡婦女每周吃6 盎司白金槍魚罐頭,；將每天食用多余 24 盎司魚的人劃為易受傷害的群體，為他們提供建議避免汞過量,。
部分原文報道如下：
When you grill a piece of salmon or have a fish taco for lunch, you're getting a good source of high-protein food that provides important nutrients. And if you're a woman who is pregnant or nursing, that fish contains important fuel for your baby's brain development.
In fact, fish is seen as such a beneficial food that the Food and Drug Administration and Environmental Protection Agency recently came out with proposed new guidelines recommending that women of childbearing age and young children eat more of it. But if Americans follow those guidelines without careful attention to which species they are consuming, they could end up taking in too much mercury.
