Final Update

Posted May 24, 2018 4:00 PM ET

This outbreak investigation is over. People should be aware that kratom could be contaminated with Salmonella and could make people sick. Contaminated products may still be available for purchase because the investigation was not able to identify a single, common source of contaminated kratom. Illnesses could continue to occur if people consume contaminated kratom. Read more on the Recalls and Advice to Consumers webpage.
