Once the Government Accountability Office did a review of food safety systems in other countries and found many things about those food safety systems that were better than ours [American].

What it requires is that first of all you identify the hazards: Where in your production chain can contamination occur? This could be a simple matter of cooking a product to kill bacteria and making sure that the product is actually brought to that temperature.

There are loopholes big enough to drive trucks through. And Congress needs to take a look at those laws and make sure that they're much more rigorous.

Here we have the great irony of modern nutrition: at a time when hundreds of millions of people do not have enough to eat, hundreds of millions more are eating too much and are overweight or obese.

You need to identify the steps at which contamination can occur - those are the critical control points. You take steps to make sure that that doesn't happen. And you monitor and evaluate and test to make sure that your system is working properly. And if it's done diligently and done faithfully and monitored carefully, then they're producing safe food. And no astronaut of which I'm aware has ever gotten food poisoning in outer space.

If we have a food supply that we can't trust, that has enormous implications for the way we view government, for the way we trust business, and for our international trade relations.

Fat is mainstream, which is why everyone has become complacent. What used to be considered pudgy before isn't even worthy of a comment today.
