CDC, public health and regulatory officials in several states, and the U.S. Food and Drug Administration (FDA) are investigating a multistate outbreak of Salmonella I 4,,12:b:- infections.
Twenty-eight people infected with the outbreak strain of Salmonella I 4,,12:b:- have been reported from 20 states. Eleven hospitalizations have been reported. No deaths have been reported.
Epidemiologic evidence indicates that kratom is a likely source of this multistate outbreak. Kratom is a plant consumed for its stimulant effects and as an opioid substitute. Kratom is also known as Thang, Kakuam, Thom, Ketom, and Biak. Ill people in this outbreak report consuming kratom in pills, powder, or tea. No common brands or suppliers of kratom products have been identified at this time.
At this time, CDC recommends that people not consume kratom in any form. The investigation indicates that kratom products could be contaminated with Salmonella and could make people sick. CDC’s recommendation may change as more information becomes available. This investigation is ongoing and we will provide updates as needed.
