The Centers for Disease Control and Prevention announced today that the multistate outbreak of Salmonella infections linked to kratom is over.
A total of 199 people infected with the outbreak strains of Salmonella were reported from 41 states. Thirty-eight percent of ill people were hospitalized, and no deaths were reported.
This outbreak included infections from several types of Salmonella: Salmonella I 4,,12:b:-, Salmonella Heidelberg, Salmonella Javiana, Salmonella Okatie, Salmonella Weltevreden, and Salmonella Thompson.
Although the outbreak investigation is over, people should be aware that kratom could still be contaminated with Salmonella and make people sick. The investigation did not identify a single, common source of contaminated kratom.
People who are at risk of severe Salmonella infection, including those with weakened immune systems, pregnant women, children under 5 years, and older adults, should avoid consuming kratom to prevent infection.
Salmonella was identified in nearly half of the kratom products tested during this investigation. Eighty-five different DNA fingerprints of Salmonella were identified in samples of kratom products. This information indicates widespread Salmonella contamination in kratom from multiple retailers.
Some kratom products that were contaminated with Salmonella have not yet been recalled and may still be available for purchase. For a list of kratom products that have tested positive for Salmonella contamination, visit: https://www.fda.gov/Food/RecallsOutbreaksEmergencies/Outbreaks/ucm597265.htm
