CDC is collaborating with public health officials in several states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Salmonella Reading and Salmonella Abony infections.
Public health investigators are using the PulseNet system to identify illnesses that may be part of this outbreak. PulseNet, coordinated by CDC, is the national subtyping network of public health and food regulatory agency laboratories. PulseNet performs DNA fingerprinting on Salmonella bacteria isolated from ill people by using techniques called pulsed-field gel electrophoresis (PFGE) and whole genome sequencing (WGS). CDC PulseNet manages a national database of these DNA fingerprints to identify possible outbreaks.
Thirty people infected with the outbreak strains have been reported from nine states. Of those ill people, 24 were infected with Salmonella Reading, 1 was infected with Salmonella Abony, and 5 were infected with both. A list of the states and the number of cases in each can be found on the Case Count Map page.
