What is the name of the national laboratory network of local, state, and federal public health labs that analyzes DNA of bacteria to quickly detect an outbreak and connect foodborne illness cases together?

• A. PulseNet
• B. FoodNet
• C. GenomeNet
• D. BioNet

Answer: (A)

PulseNet is the national public health laboratory network that links local, state, and federal labs by comparing DNA fingerprints of bacterial pathogens to detect outbreaks quickly and connect related foodborne illness cases across different areas. By standardizing laboratory methods and sharing DNA-pattern data in a centralized system, PulseNet lets clinicians and investigators see when separate illnesses are caused by the same strain, signaling a single outbreak even if cases are far apart. This rapid linkage is what enables faster recalls and interventions to protect the public.

FoodNet, by contrast, collects data on the incidence and burden of foodborne illnesses rather than serving as the lab network for DNA analysis. GenomeNet and BioNet are not the established public health laboratory networks used for this purpose.
