CDC investigates multistate Salmonella outbreak linked to greens supplement powder

Federal health officials are investigating a multistate outbreak of Salmonella infections that the Centers for Disease Control and Prevention (CDC) has linked to a powdered greens supplement. In an investigation update dated January 14, 2026, the CDC reported that epidemiologic data suggest Live it Up Super Greens supplement powders may be contaminated with Salmonella Typhimurium and could be making people sick.

The CDC’s update states that, as of January 14, 2026, 45 people infected with the outbreak strain were reported across 21 states. Of those with available information, 12 people were hospitalized, and no deaths were reported. Illness onset dates ranged from August 22, 2025 to December 30, 2025, indicating the outbreak may have unfolded over months before being detected and consolidated into a single national investigation.

The agency emphasized a familiar caution in outbreak investigations: the reported case count likely understates the true number of illnesses. Many infected people recover without seeing a doctor or without being tested, and there is often a reporting lag of several weeks as public-health labs confirm strains and connect cases to an outbreak cluster.

To identify the source, investigators compile detailed exposure histories, asking sick people what they consumed in the week before symptoms began. The CDC said public-health and regulatory officials are collecting different types of data, including epidemiologic and laboratory evidence, to confirm the suspected product link and to understand how contamination may have occurred.

For consumers, the guidance is practical and immediate. The CDC advises that anyone who has recalled products at home should throw them away or return them to the store. People who consumed the product and develop symptoms consistent with Salmonella infection—such as diarrhea, fever, and stomach cramps—should consider seeking medical advice, particularly if they are at higher risk for severe illness.

The outbreak also underscores a broader health trend: supplements and powdered products are not sterile, and they can carry microbial risks if contamination occurs during manufacturing, packaging, or storage. The CDC’s investigation will likely continue with additional case updates, refined exposure data, and potential further actions in coordination with regulators as officials work to limit additional illnesses.
