燕麥真的含有殺蟲劑嗎?

"Unsafe levels of a weed killer chemical in oat products," cries a headline from CNN published earlier this week. The accompanying article cites a new report from the Environmental Working Group (EWG), a nonprofit advocacy organization, that revealed traces of glyphosate-the main ingredient in the pesticide Roundup-in several types of oat cereal, oatmeal, granola, and snack bars. Almost three-quarters of food samples tested "showed higher glyphosate levels than what the group's scientists believe to be 'protective of children's health,'" CNN reported.

"燕麥產品含有不安全量的除草劑化學物，"CNN本週初發布的一篇新聞如是哭訴。隨後，一篇文章引用了非營利性倡導組織環境工作組（EWG）發佈的一份新報告，該報告揭露多種燕麥穀物、燕麥片、格蘭諾拉麥片和零食棒中都含有草甘膦--農達有機磷除草劑的主要成分。所測食物樣品中，近四分之三的樣品"含有較高水平的草甘膦，超過了科學家所認爲的'對兒童健康無害'的水平，"CNN報道。

This sounds pretty scary, especially for anyone who eats oats regularly. (At Health, that's a lot of us-the whole grain lowers cholesterol, burns fat, and fills you up with fiber, folate, and potassium.) Plus, we've been hearing a lot about Roundup lately: Last week, a California jury awarded $289 million to a man who says he got cancer from repeated exposure to the chemical during his years as a pest-control manager for the San Francisco school district.

聽起來怪可怕的，經常吃燕麥的人聽到這一消息更爲憂心。（在《健康》雜誌內部，很多人都有吃燕麥--這一全穀物能降低膽固醇、燃燒脂肪、提供纖維、葉酸和鉀元素。）此外，近來我們聽說了很多有關農達的新聞：上週，加州陪審團獎勵了一名男子（2.89億美元），該男子稱他在舊金山學區擔任控蟲經理，多年來與農達的不斷接觸使他患了癌症。

What is glyphosate, and why is it in our food?

什麼是草甘膦？食物爲何含有草甘膦？

Glyphosate is the most widely used herbicide in the world, and is used in hundreds of weed-killing products. Many health and agricultural experts say that humans don't absorb glyphosate in the same way they do harmful chemicals like DDT, so it's safe in low quantities-like what's left on sprayed crops after they're harvested, cleaned, and prepared for food sales.

草甘膦是世界上使用最廣的除草劑，用於成百上千種除草產品。很多健康和農業專家表示，人類不會像吸收滴滴涕有害化學物那般吸收草甘膦，所以少量草甘膦不會帶來危害--比如收穫農作物，將其洗淨準備售賣時，殘留在農作物上的草甘膦量是安全的。

In 2015, however, the International Agency for Research on Cancer classified glyphosate as a "probable human carcinogen" after studies linked it to non-Hodgkin's lymphoma. In 2016, the FDA announced that it would begin testing for glyphosate in four widely used crops: soybeans, corn, milk, and eggs.

然而，在2015年，當各類研究將草甘膦與非霍奇金淋巴瘤聯繫在一起之後，國際癌症研究機構將其歸類爲"可能誘發人類癌症的物質"。2016年，食品與藥品監管局宣佈，將對四種廣泛使用草甘膦的農作物進行測試：大豆、玉米、牛奶和雞蛋。

So how much is really there?

所以燕麥中草甘膦的含量究竟有多少？

First, the bad news: It's true that glyphosate has been found in several types of oat products. Scientists from the U.S. Food and Drug Administration (FDA) have even spoken about this themselves: FDA researcher Narong Chamkasem highlighted the amounts found in samples of instant oatmeal. These quantities ranged from 0.3 to 1.67 parts per million.

首先，壞消息是：的確在幾種燕麥產品中發現了草甘膦。美國食品與藥品監管局的科學家也談及了這一點：食品與藥品監管局的研究員Narong Chamkasem強調了即食燕麥片樣品中的草甘膦含量。從百萬分之0.3至百萬分之1.67不等。
