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.

BASICS OF DIET AND HEALTH The basic principles of good diets are so simple that I can summarize them in just ten words: eat less, move more, eat lots of fruits and vegetables. For additional clarification, a five-word modifier helps: go easy on junk foods.

When you have a food safety system that's voluntary and not mandatory, you're in a situation in which everybody wants everybody else to go first. So as a normal course of doing business, food companies cut corners and don't want to take the kind of trouble and the kind of testing and the kind of careful procedures that are required to produce the safe food because they don't have to.

The Centers for Disease Control says that there are 76 million cases of food poisoning in the United States every year, 350,000 hospitalizations, and 5,000 deaths. Is that a lot or a little? Well, it depends on how you look at it.

I live in the United States, and I'm not moving. But from the standpoint of food safety, the countries in Scandinavia do it better than we do. It's not that they don't have food-poisoning incidents; it's that there are many fewer in proportion to the population.

I would require every producer of food to follow and have enforced a standard safety plan. We know how to produce safe food. It has a horrible name; it's called HACCP - Hazard Analysis and Critical Control Point - and this was a food safety system that was developed for NASA so that astronauts wouldn't get sick in outer space. If you just think about what it might be like to have food poison under conditions of zero gravity, you don't even want to think about it.
