The Drug Enforcement Administration is looking at stronger restrictions on the sales of kratom, which is currently traded freely on the internet and in some stores. Advocates say it works as a stimulant in small doses, but can help people overcome opiate dependency in larger doses. It’s sold under a variety of names, including Thang, Kakuam, Thom, Ketom, and Biak.
Salmonella is a very common bacteria that causes food poisoning. The CDC says it is not clear how it could have gotten into supplies of kratom. It's been linked to supplements before, and caused an outbreak in food powder in 2016.
