"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.
"燕麦产品含有不安全量的除草剂化学物，"CNN本周初发布的一篇新闻如是哭诉。随后，一篇文章引用了非营利性倡导组织环境工作组（EWG）发布的一份新报告，该报告揭露多种燕麦谷物、燕麦片、格兰诺拉麦片和零食棒中都含有草甘膦--农达有机磷除草剂的主要成分。所测食物样品中，近四分之三的样品"含有较高水平的草甘膦，超过了科学家所认为的'对儿童健康无害'的水平，"CNN报道。
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.
听起来怪可怕的，经常吃燕麦的人听到这一消息更为忧心。（在《健康》杂志内部，很多人都有吃燕麦--这一全谷物能降低胆固醇、燃烧脂肪、提供纤维、叶酸和钾元素。）此外，近来我们听说了很多有关农达的新闻：上周，加州陪审团奖励了一名男子（2.89亿美元），该男子称他在旧金山学区担任控虫经理，多年来与农达的不断接触使他患了癌症。
What is glyphosate, and why is it in our food?
什么是草甘膦？食物为何含有草甘膦？
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广的除草剂，用于成百上千种除草产品。很多健康和农业专家表示，人类不会像吸收滴滴涕有害化学物那般吸收草甘膦，所以少量草甘膦不会带来危害--比如收获农作物，将其洗净准备售卖时，残留在农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，当各类研究将草甘膦与非霍奇金淋巴瘤联系在一起之后，国际癌症研究机构将其归类为"可能诱发人类癌症的物质"。2016年，食品与药品监管局宣布，将对四种广泛使用草甘膦的农作物进行测试：大豆、玉米、牛奶和鸡蛋。
So how much is really there?
所以燕麦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，坏消息是：的确在几种燕麦产品中发现了草甘膦。美国食品与药品监管局的科学家也谈及了这一点：食品与药品监管局的研究员Narong Chamkasem强调了即食燕麦片样品中的草甘膦含量。从百万分之0.3至百万分之1.67不等。
