Health officials have recently linked nearly a dozen salmonella cases across seven states to powdered supplements available at Sam’s Club, as announced this past Friday.

The Food and Drug Administration (FDA) alongside the U.S. Centers for Disease Control and Prevention (CDC) is actively investigating the Member’s Mark Super Greens Powder Supplements. These supplements, which have been distributed both in-store nationwide and online, are at the center of this salmonella outbreak.

Due to potential contamination with salmonella bacteria, the CDC has confirmed that these products have been pulled from Sam’s Club shelves. The specific contaminant has been identified as moringa leaf powder found in the supplements.
