Federal and state health officials announced the investigation into a multistate outbreak of Salmonella I 4,,12:b:- infections linked to the consumption of kratom. To date, 28 cases, including eleven hospitalizations, have been reported in 20 states.
In interviews, ill people answered questions about the foods they ate and other exposures in the months before they became ill. Eight (73%) of 11 people interviewed reported consuming kratom in pills, powder, or tea.
No common brands or suppliers of kratom products have been identified.
Kratom is a plant native to southeast Asia that is consumed for its stimulant effects and as an opioid substitute. It is typically brewed in a tea, chewed, smoked, or ingested in capsules. Kratom may also be known as Thang, Kakuam, Thom, Ketom, and Biak.
The investigation indicates that kratom products could be contaminated with Salmonella and could make people sick.
The most common symptoms of salmonellosis are diarrhea, abdominal cramps, and fever within 12 to 72 hours after eating the contaminated product. The illness usually lasts 4 to 7 days. Most people recover without treatment. In some persons, however, the diarrhea may be so severe that the patient needs to be hospitalized. Older adults, infants, and persons with weakened immune systems are more likely to develop a severe illness. Individuals concerned about an illness should contact their health care provider.
