WASHINGTON, D.C. — Federal health officials warned consumers to stop using certain “super greens” and moringa supplements after a growing Salmonella outbreak was tied to contaminated moringa leaf powder, while the Centers for Disease Control and Prevention said a separate border health initiative has surpassed one million voluntary participants.

In a food safety alert updated Thursday, the CDC said 65 people across 28 states have been reported in the outbreak and that an additional strain of Salmonella is now included in the investigation. The agency said epidemiologic, laboratory and traceback evidence shows moringa leaf powder is contaminated and is making people sick.

The outbreak has triggered multiple recalls, including a new one announced Wednesday by Why Not Natural for its Pure Organic Moringa Green Superfood capsules, lot No. A25G051, with an expiration date of 07/2028. The CDC said the product is sold nationwide in 120-capsule bottles.

Earlier this month, Superfoods Inc., doing business as Live it Up, recalled all Live it Up Super Greens supplement powders with expiration dates from August 2026 through January 2028, including Original and Wild Berry flavors, sold nationwide in both bags and stick packs. The company said the recall covers lots beginning with the letter “A” and all stick pack products, and that the products were sold through its direct-to-consumer website since September 2024 and on Amazon.com since July 30, 2025, with possible unauthorized third-party distribution through sites including ebay.com and Walmart.com. The company said product also reached consumers in the United Kingdom.

The company listed recalled products as Live it Up Super Greens (UPC 860013190804), Live it Up Super Greens 30 stick packs (UPC 850077468063), Live it Up Super Greens Wild Berry (UPC 860013190811) and Live it Up Super Greens Wild Berry 30 stick packs (UPC 850077468070), noting the products are packaged in green pouches and that lot codes are printed on the bottom back of the packaging.

Superfoods Inc. said there have been 45 illnesses and 12 hospitalizations linked to a single product, and that production has been suspended while the FDA and the company investigate. The company said consumers can request a refund by contacting recall@artofenso.com with their name, order number and a photo of the product showing the affected lot code.

The CDC urged consumers not to eat recalled dietary supplements and to throw them away or return them to where they were purchased. Officials also advised washing items and surfaces that may have touched the products using hot, soapy water or a dishwasher, and calling a healthcare provider for severe symptoms.

Salmonella infections typically cause diarrhea, fever and stomach cramps six hours to six days after exposure, the CDC said. Illness usually lasts four to seven days and most people recover without treatment, but severe cases can lead to hospitalization, particularly for children younger than 5, adults 65 and older, and people with weakened immune systems.

In a separate announcement Friday, the CDC said its Traveler-Based Genomic Surveillance program has surpassed one million voluntary participants, a milestone the agency described as strengthening the nation’s ability to detect emerging public health threats at U.S. borders.

The program collects voluntary, anonymous samples from arriving international travelers at select U.S. airports to provide early insight into emerging pathogens and variants before they spread widely in the United States. “The United States is the world’s leading authority in public health,” said HHS Deputy Secretary and Acting CDC Director Jim O’Neill. “The broad participation of travelers enhances our ability to safeguard the nation using tools that are developed, operated, and governed here at home without reliance on unaccountable global bureaucracies.”

Launched in 2021, the program operates through public-private partnerships that include Ginkgo Biosecurity and XWell, along with cooperation from select airports. The CDC said it has also analyzed more than 2,600 airplane wastewater samples as part of broader biosurveillance efforts and pointed to the program’s early detection of an influenza H3N2 subclade that was posted to public repositories days before the next publicly reported sequence.
