Salmonella is an important risk to Kratom users.  As of May 24, 2018, an outbreak of 199 cases of salmonellosis in which Kratom was identified of the likely source caused a recall of the product in 41 states.  

Kratom is high risk for carrying Salmonella, possibly due handling practices of the countries where it is grown and processed. 

Although Salmonella requires a fairly high water activity to grow, the bacteria can survive quite well in dried products, including Kratom leaves, pills, capsules, and powders.  In some individuals, it only takes 1 cell of Salmonella to cause disease.  

MBL uses Polymerase Chain Reaction (PCR) to detect Salmonella in Kratom samples.  This technology can detect as little as 1 Salmonella cell in a sample.
