National surveillance of foodborne diseases at a group of sentinel public laboratories around the nation, sophisticated technologies such as DNA fingerprinting to pinpoint specific bacterial subtypes responsible for an outbreak, and computer networks that link and analyze the findings of far-flung laboratories may soon provide public health experts with an early warning system far beyond what is possible today.
