"Labeling is much better than it used to be."
Marian Burros, retired New York Times food columnist.
"And when you read the labels you should really read them very, very carefully. Because they'll give you all kinds of clues that you didn't expect to see."
Burros spoke April 24th at a symposium honoring N.Y.U. food researcher Marion Nestle called Marion Nestle and the State of Food: Policy, Media, Education and More.
"A lot of people are now labeling with GMOs. I don't worry about GMOs as much as I worry about the pesticides that are put on GMOs. I think that they're very, very questionable. There are a lot of signs. There's big, big disagreement in the scientific community."
"So, there's nothing in food today that isn't political, but what is changing to a certain extent...is what consumers expect from their food. And it's a whole lot more than they used to expect. They want fresh food. They want clean food. I'm not sure they know what clean food means, and I'm not sure I know what clean food means either. I don't think it has anything to do with whether it's been washed or not, though. How many people know about romaine lettuce in this audience right now?"
A recent E. coli outbreak traced to romaine from Yuma, Arizona, has so far hospitalized almost 50 people around the country. The CDC has recommended avoiding romaine unless it's definitely not from the Yuma area.
"The federal government says that they're not going to do any more than tell everybody that this is a problem, and not to eat it. They're not going to look any further into it. Because the romaine will be coming from somewhere else than the place where it's coming from right now, so everything will be settled. Well, everything won't be settled. But that's the kind of government you have to deal with. So, you have to be your own scientist, your own investigator, maybe you have to spend more time in the supermarket than you really want to spend in the supermarket."
"But the other kinds of things people are anxious to have are things that are very easy and quick to do, but are very healthful. So, they want purity—a lot of people want organics...I can go into Walmart and get lots and lots of organics. Well, that's the last place in the world I would ever have expected to find organics. But you can find them."
"So, what you have today is a combination of some things getting better. But you can't ever let down your guard...and even though it's really a pain in the neck you have to look very carefully at everything you buy and don't pay attention to any of the advertising. None of it. Because that's not really what you need to know."

“在看标签时，你应该非常仔细 。因为标签会提供各种你不曾预料到的线索 。”
“许多人现在都在商品上标注‘转基因食品' 。我不太担心转基因食品，我更担心的是转基因食品上喷的杀虫剂 。我认为这非常非常可疑 。有很多迹象表明这一点 。目前这在科学界存在巨大争议 。”
“因此，现在没有哪种食物不存在政治性，但是在一定程度上正在改变的是消费者对食物的期望 。人们期待的比以前多了很多 。现在他们想要新鲜的食物 。他们还想要洁净的食物 。我不确定他们是否清楚洁净的食物意味着什么，不过我也不清楚这意味着什么 。但是我认为这与食物是否清洗没有任何关系 。在座的人中有多少人了解长叶生菜？”
最近亚利桑那州尤马市种植的长叶生菜爆发大肠杆菌，目前已造成全美近50人入院治疗 。美国疾病控制中心（简称CDC）建议民众避免食用长叶生菜，除非他们确定生菜不是来自尤马地区 。
“联邦政府表示，除了告知所有人这是一个问题、不要食用这种生菜以外，他们不会采取其他措施 。他们不会深入调查 。因为现在市面上的长叶生菜都来自其他地区，而不是来自有问题的地区，那一切都解决了 。但是，并不是一切都得到了解决 。可你不得不和这样的政府打交道 。因此，你一定要成为自己的科学家，成为自己的调查员，也许你在超市里花的时间不得不比你期望的要多 。”
“但人们渴望的其他东西简单又快捷，同时又很健康 。他们想要的是纯净，许多人想要有机食品，我可以在沃尔玛买到很多有机食品 。而我曾认为那是世界上最不可能找到有机食品的地方 。但是现在大家能在沃尔玛买到了 。”
“因此，大家现在收获的是一些逐渐改善的事情 。但是你们永远不能放松警惕，尽管极为仔细地查看你购买的每一件商品是件烦人的事，而且不要关注任何广告 。所有广告都不行 。因为你没必要知道那些信息 。”
