Consumers get part of the credit, for handling food more safely at home, but experts say the biggest improvement came from better industry controls and inspections.

"The food is actually cleaner to begin with," said Dr. Robert Tauxe, top food scientist at the federal Centers for Disease Control and Prevention. Certain germs have dramatically declined, and "that to me is really solid progress."

However, the trend could reverse in coming years if fruit and vegetable growers do not address problems like those that led to the spinach scare, Tauxe and others said.

"The meat and poultry industry has made great strides. The produce industry has a long way to go to catch up," said Michael Doyle, a microbiologist who heads the University of Georgia's Center for Food Safety.
