FDA Links Kratom to Salmonella Outbreak

Officials with the CDC and the FDA are investigating a multistate outbreak of salmonellosis from a rare strain of Salmonella I 4,[5],12:b, and have recommended that individuals do not consume kratom in any form because it could be contaminated.

On February 6, the FDA classified kratom, a botanical substance widely used as a painkiller, despite agency approval, as an opioid.

As of February 16, there have been 20 states to report that 28 people are infected with the outbreak Salmonella strain, 11 people have been hospitalized and no deaths have been reported. Those ill range in age from 6—67 years.

CDC officials report that the epidemiologic evidence collected indicates that products reported to be kratom or contain kratom are a likely cause of the outbreak. Whole genome sequencing performed on ill isolates are closely related genetically, meaning that people in the outbreak are more likely to share a common source of infection.

FDA officials note there are no FDA-approved uses for kratom, and it's not safe for any medical use, including for the treatment of opioid withdrawal symptoms. The agency has received reports concerning the safety of kratom, including deaths that are potentially associated with it.
