Measles cases surge in South Carolina as FDA and CDC track Salmonella outbreak linked to greens supplement

U.S. health officials are confronting multiple outbreaks at once, with measles and Salmonella drawing particular attention in late January. In South Carolina, the state’s Department of Public Health reported a fast-growing measles outbreak that has reached 700 cases, including 54 new cases confirmed over just three days. A HealthLeaders summary citing CIDRAP noted that the CDC has confirmed 416 total U.S. measles cases so far in 2026, with infections rising sharply in recent weekly reporting.

Separately, federal agencies are investigating a multistate Salmonella Typhimurium outbreak linked to Live it Up-brand Super Greens dietary supplement powder. The FDA’s outbreak page said the product includes original and wild berry flavors, with expiration dates spanning 08/2026 to 01/2028, and is largely sold online through the company site and major marketplaces. The FDA advised consumers and retailers not to eat, sell, or serve the products and to discard or return them.

As of the FDA’s January 14, 2026 update, 45 illnesses were reported across 21 states, with 12 hospitalizations and no deaths. Illness onset dates ranged from August 22, 2025, through December 30, 2025, underscoring how long outbreak investigations can take as epidemiologists match lab results, purchase histories, and exposure patterns.

The CDC’s timeline page emphasized that recent Salmonella illnesses may not yet be reflected in official counts, because it can take three to four weeks to determine whether a sick person’s infection is part of an outbreak strain. The agency also noted that reported numbers typically undercount true cases, since many people recover without medical care and are never tested.

Together, the measles and Salmonella updates highlight the dual challenge for public health: preventing highly contagious, vaccine-preventable disease spread on one front, while rapidly identifying and removing contaminated consumer products on another. Officials continue to urge people to follow public guidance closely—especially around vaccination, safe handling, and recall notices—because the window between exposure and confirmed reporting can be long enough for outbreaks to accelerate.
