CDC investigates multistate Salmonella outbreak linked to “super greens” supplement powder; voluntary recall announced

The U.S. Centers for Disease Control and Prevention (CDC) said it is investigating a multistate outbreak of Salmonella infections linked to a greens supplement powder, urging consumers to stop using the recalled products and to discard or return them. The investigation update, posted January 14, 2026, described a pattern of illnesses across multiple states and said public health and regulatory officials are coordinating to identify how contamination occurred and to prevent additional cases.

CDC reported that 45 people infected with the outbreak strain had been identified across 21 states as of the update, with illness onset dates spanning late August 2025 through late December 2025. Among people with available information, a portion required hospitalization, and the agency said no deaths had been reported in the data summarized at that time.

Investigators said interviews with sick people indicated a strong link to the supplement powder, with a large share of interviewed patients reporting consumption before becoming ill. CDC emphasized that outbreaks often look smaller in official counts than they truly are because many people recover without seeking medical care or testing, and because there is a lag between illness onset and reporting in surveillance systems.

In addition to interview data, CDC described laboratory work that compares bacterial samples from patients. The agency said genetic analysis showed samples were closely related, supporting the conclusion that people became sick from the same contaminated source. Officials also said they were working with the U.S. Food and Drug Administration (FDA) on traceback and product sampling as part of the ongoing investigation.

The company behind the product informed FDA it would initiate a voluntary recall, CDC said. Health officials advised consumers not to eat, sell or serve the recalled powders, and to take practical steps such as cleaning containers or surfaces that may have been exposed. Because Salmonella can spread through cross-contamination in kitchens and food-prep areas, public health guidance often includes careful handwashing and thorough cleaning of items that contacted the product.

Consumers experiencing symptoms such as diarrhea, fever or stomach cramps after using the recalled supplement were advised in CDC materials to seek medical guidance, particularly for higher-risk groups. Officials stressed that the investigation may evolve as new illnesses are reported and as additional testing is completed, and they encouraged the public to watch for updated recall and outbreak notices.
