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.

One way in which we can encourage the Chinese government to take more vigorous action to control food safety in their country is by just saying we're not going to buy Chinese foods until they get their system cleaned up. Admittedly it's a difficult system to get under control because an astonishing percentage - maybe 80 percent - of the foods in China are produced in small backyard operations.

They (food companies) are putting $36 billion into directing those choices. And their methods are very effective.

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.

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.

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.

Nutrition science, however, suggests that golden rice alone will not greatly diminish vitamin A defi-ciency and associated blindness. [”¦] People whose diets lack [fats and proteins] or who have intestinal diarrheal diseases -- common in develop-ing countries -- cannot obtain vitamin A from golden rice.
