Meat is produced under HACCP plans. Meat and poultry are required to be produced under standard food safety plans and they have been since the mid-'90s, and there are now fewer problems with meat than there used to be. That's on the USDA's side.

We don't really have any that protect the food supply from farm to table. We have a food safety system that's piecemeal, largely divided between two agencies that don't talk to each other very much. Neither agency can enforce regulations from the farm to the table.

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.

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.

The pet food recall, which was after all just about pets, and treated as if it were an inconsequential matter, was an absolute forerunner of what's going on in China, where 50,000 infants have been sickened because of a contaminated infant formula. So these things are all closely related. You cannot separate the food supply for pets, farm animals, and people, and you cannot separate problems in one area of a country from problems in another area.

It's a tremendous way of getting people to buy more at lower cost to the producer. There's no question that that's an incentive to buy. Everybody loves a bargain.

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.
