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.

If you're sick, first you have to associate your sickness with a food. Then you have to report it to your doctor. Then the doctor reports it to some state authority. The state authority reports it to the federal authority. By the time all that happens, two weeks have gone by.

We don't have a farm-to-table food safety system. I keep saying this. It came as a big surprise to the FDA that tomatoes were being grown in the United States, sent to Mexico for packing, and then sent back. I mean, they had no idea that our food chain worked like this.

The standard four food groups are based on American agricultural lobbies. Why do we have a milk group? Because we have a National Dairy Council. Why do we have a meat group? Because we have an extremely powerful meat lobby.

What we know about diets hasn't changed. It still makes sense to eat lots of fruits and vegetables, balance calories from other foods, and keep calories under control. That, however, does not make front-page news.

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.
