Federal health and regulatory agencies are investigating an outbreak of Salmonella Newport of unknown origin that involves 125 cases in 15 states.
The Centers for Disease Control and Prevention and Food and Drug Administration, along with health agencies in the states, are identifying cases through the PulseNet network, which links public health and food regulatory agency labs and is coordinated by the CDC. Whole genome sequencing has linked the cases in the outbreak, but as of July 20, no food source had been found as a possible source.
According to the CDC, illness onsets range from June 19 to July 7, and on July 10, PulseNet identified the outbreak with 13 cases in three states; in 10 days, the cases had risen to 125 in 15 states.
It takes an average of two to four weeks from when someone becomes ill and when it is reported, according to the CDC.
Although health officials are interviewing ill people about foods they’ve eaten in the week before they got sick, a specific food, grocery store or restaurant chain has not been identified, according to the CDC notice.
