CDC Warns of Dual Food Outbreaks: Deadly Listeria and Salmonella Spread Nationwide

WASHINGTON, D.C. — Federal health officials are sounding the alarm over two separate foodborne illness outbreaks sweeping across multiple states — one linked to ready-to-eat meals contaminated with Listeria monocytogenes, and another tied to powdered supplements containing moringa leaf powder that tested positive for Salmonella.

The Centers for Disease Control and Prevention (CDC) reported Friday that seven new Listeria cases — including six hospitalizations and two deaths — have been confirmed since the agency’s last update. The fatalities occurred in Hawaii and Oregon. Health investigators are working to determine whether the newly ill consumed previously recalled meals or if additional products may be contaminated.

Consumers are being urged to check their refrigerators and freezers for recalled prepared foods associated with the Listeria outbreak, which has been linked to chicken fettuccine alfredo and other ready-to-eat items. Officials warn that Listeria bacteria can survive refrigeration and spread easily to other foods and surfaces.

“Do not eat recalled foods — throw them away or return them,” the CDC advised. The agency also cautioned vulnerable populations — pregnant women, adults over 65, and people with weakened immune systems — to be especially vigilant, as Listeria infections can lead to miscarriages, premature births, or life-threatening complications.

In a separate investigation, the CDC announced a Salmonella outbreak tied to moringa leaf powder used in dietary supplements, including Member’s Mark Super Greens products sold at Sam’s Club stores nationwide and online. Eleven people across seven states have fallen ill, with three requiring hospitalization.

The Food and Drug Administration traced the contamination to a single lot imported from Vallon Farm Direct PVT LTD in India. Sam’s Club has halted distribution of the affected supplements, but officials warn that consumers may still have them at home.

The CDC urged consumers to discard any Member’s Mark Super Greens powders containing moringa leaf or return them to the store. Businesses have been instructed not to sell or serve the products and to sanitize all surfaces that may have been exposed.

Salmonella infections typically cause diarrhea, fever, and stomach cramps within a few hours to several days of exposure. While most people recover without medical treatment, severe cases can result in hospitalization or death, especially among children, the elderly, and the immunocompromised.

Health officials continue to investigate both outbreaks and advise anyone who experiences symptoms of foodborne illness to seek immediate medical attention.
