Salmonella Outbreak Statistics in US 2026 | Key Facts

What Is a Salmonella Outbreak?

Salmonella refers to a genus of rod-shaped bacteria that live in the intestinal tracts of animals and humans, causing an illness called salmonellosis — characterized by diarrhea, fever, stomach cramps, nausea, and vomiting. Symptoms typically begin 6 hours to 6 days after exposure and last between 4 and 7 days in otherwise healthy individuals. A Salmonella outbreak is officially declared when two or more people contract the same illness from the same contaminated food, drink, or animal source.

In the United States, outbreaks are tracked through CDC’s national surveillance platforms — including PulseNet, FoodNet, and the System for Enteric Disease Response, Investigation, and Coordination (SEDRIC) — which use whole genome sequencing (WGS) to genetically link cases across state lines and rapidly identify clusters. The diversity of outbreak sources now encompasses raw oysters, cage-free eggs, green supplement powders, pet reptiles, home delivery meal kits, and more — making Salmonella in 2025–2026 one of the most unpredictable foodborne threats Americans face.

What makes recent statistics so alarming is not just the frequency of outbreaks but troubling trends emerging around them. The number of Salmonella-related food recalls jumped from 27 in 2023 to 41 in 2024 — a 52% increase in a single year. Hospitalizations tied to contaminated food outbreaks more than doubled in 2024. A 2025 CDC study estimates Salmonella alone costs the US economy approximately $17 billion annually — the highest economic burden of any single foodborne pathogen — and approximately 1 in 30 Salmonella infections is ever diagnosed through laboratory testing.

Key Facts: Salmonella Outbreak in the US (2025–2026)

Sources: CDC Salmonella Infection Overview (2025); CDC FoodNet 2023 Preliminary Data (MMWR, July 2024); USDA ERS Cost Estimates of Foodborne Illnesses (Hoffmann et al., 2025); US PIRG Food for Thought 2025 Report; GAO Food Safety Report GAO-25-107606, January 2025; USDA FSIS Salmonella By the Numbers (2025); CDC Multistate Outbreak Investigation Reports, 2025–2026.

The updated CDC/USDA FSIS estimate of 1.35 million annual Salmonella illnesses — revised upward from the prior 1.2 million figure — reflects improved methodology capturing a broader scope of infection. The simultaneously updated hospitalization estimate of 26,500 (vs. the prior 23,000) underscores the continued severity of these illnesses. CDC has also revised the underreporting ratio: approximately 1 in every 30 Salmonella infections is ever lab-confirmed, meaning the true annual burden is dramatically higher than official case counts reflect.

The 52% surge in Salmonella food recalls in a single year (2023 to 2024), combined with USDA FSIS data showing a 22% increase in the proportion of poultry samples testing positive for Salmonella — against a stated goal of a 4% reduction — confirms that the federal food safety apparatus is falling short of its own benchmarks. For a pathogen that costs the American economy $17 billion a year (roughly 23% of the entire $74.7 billion US foodborne illness economic burden), the gap between the scale of the problem and the adequacy of the response remains stark.

Recent Salmonella Outbreaks in the US – Active & Closed (2025–2026)

An important correction from earlier reporting: the raw oyster outbreak linked to Salmonella Telekebir recorded a final hospitalization count of 34 of 68 patients (50%) — significantly higher than the preliminary count of 20 hospitalizations cited in December 2025 interim updates. The 50% rate is well above the typical rate for oyster-linked Salmonella outbreaks and reflects the particular severity of this strain.

The supplement powder outbreak — confirmed at 65 people across 28 states as of January 29, 2026 — remains an active public concern. CDC and FDA traced contamination to moringa leaf powder, a shared ingredient in both Live it Up Super Greens and Why Not Natural Pure Organic Moringa Green Superfood capsules, with a recall expansion covering both brands issued January 28, 2026. Recalled products bear expiration dates through January 2028, meaning contaminated product may still be in consumers’ pantries.

The gecko outbreak, closed January 9, 2026, involved 113 confirmed cases across 36 states from three simultaneous strains. The Salmonella Muenchen strain matches a 2015 US outbreak, and Salmonella Oranienburg showed fosfomycin resistance in 29 samples — a resistance pattern documented in the CDC’s WGS analysis. This outbreak illustrates how animal-contact transmission routes can sustain large, multi-year outbreaks that evade public attention because they do not originate from a recalled supermarket product.

Salmonella Outbreak by Food Source (2025–2026)

Sources: CDC Salmonella Multistate Outbreak Investigation Reports, 2025–2026; USDA FSIS Outbreak Investigations; FDA Outbreak Investigation Notices; CDC MMWR Vol. 74 No. 31 (August 2025) — bearded dragon S. Cotham outbreak.

The antibiotic resistance dimension of 2025 outbreak data is a growing concern. In the Country Eggs, LLC outbreak, WGS analysis found that bacteria from 94 of 105 patient samples showed predicted resistance to nalidixic acid and reduced susceptibility to ciprofloxacin — a fluoroquinolone antibiotic among the most commonly recommended treatments for severe Salmonella infections. This strain was found genetically related to S. Enteritidis isolated from chicken, eggs, and backyard poultry, directly connecting poultry industry antibiotic use to human health outcomes. All 21 samples from the Metabolic Meals outbreak also showed ciprofloxacin non-susceptibility, indicating this resistance pattern is appearing across multiple concurrent outbreaks — not isolated incidents.

The bearded dragon outbreak, documented in MMWR Vol. 74 No. 31 (August 2025), confirmed that infants under 1 year were disproportionately represented in the 2024 S. Cotham outbreak, comprising 65% of cases — and that most had only indirect contact with the reptile (the animal was allowed to roam freely in the home). The same rare strain reemerged in 2025, raising serious questions about biosecurity in the commercial pet reptile supply chain.

Salmonella Annual Illness Burden – Core National Statistics (2025)

Sources: USDA FSIS Salmonella By the Numbers (2025); CDC About Salmonella Infection (2025); CDC Burden Estimates, April 2025; CDC FoodNet 2023 Preliminary Data, MMWR July 2024; USDA ERS Cost Estimates of Foodborne Illnesses (Hoffmann et al., 2025); GAO-25-107606, January 2025.

The updated annual illness burden statistics — 1.35 million illnesses, 26,500 hospitalizations, and 420 deaths — reflect a 2025 revision by USDA FSIS and CDC, superseding prior estimates. These should be used in place of any earlier statistics for current reporting. The revised underreporting ratio of approximately 1 in 30 means roughly 40.5 million exposure events annually when projected against confirmed case counts, making Salmonella’s true US burden far larger than official surveillance captures.

CDC’s FoodNet, covering 16% of the US population, reported in its 2023 preliminary data (the most recent published, released July 2024) that Salmonella incidence remains above the Healthy People 2030 target rate. The GAO’s January 2025 audit found FSIS saw poultry contamination rates worsen by 22% against a 4% reduction target. With Salmonella generating approximately $17 billion in annual economic costs — against a total all-pathogen US burden of $74.7 billion in 2023 dollars — Salmonella alone accounts for roughly 23% of the entire national foodborne illness economic burden.

Salmonella High-Risk Populations in the US – 2025–2026 Data

Sources: CDC Salmonella Infection — People at Higher Risk (2025); CDC Multistate Outbreak Investigation Reports, 2025–2026; CDC MMWR Vol. 74 No. 31 (August 2025) — bearded dragon S. Cotham outbreak.

The antibiotic resistance picture emerging from 2025 outbreak data is a particular concern for high-risk patients who develop invasive disease. Ciprofloxacin non-susceptibility was documented in 94 of 105 samples from the Country Eggs LLC outbreak and all 21 samples from the Metabolic Meals outbreak — two independent outbreak events in 2025. For high-risk patients who require antibiotic treatment and encounter a resistant strain, the consequences can be life-threatening. This is not a theoretical future risk; it is already appearing in confirmed US outbreak data.

The bearded dragon outbreak data (MMWR Vol. 74 No. 31, August 2025) showed that most infant cases had only indirect contact with the reptile — the bearded dragon roamed freely in the home. This fundamentally broadens the risk model: household exposure to an infected pet reptile is sufficient for transmission to the most vulnerable, regardless of direct handling.

Salmonella Recalls & Food Safety Response – Regulatory Statistics (2025–2026)

Sources: US PIRG Education Fund, Food for Thought 2025 Report (February 2025); US Government Accountability Office, GAO-25-107606 (January 2025); USDA FSIS Recall and Outbreak Data; FDA Outbreak Investigation Notices, 2025–2026.

The regulatory landscape entering 2026 reflects a sharp tension between sophisticated detection capability and significant structural gaps in prevention and coordination. CDC’s PulseNet WGS network continues to demonstrate its value — identifying the supplement powder cluster within weeks and linking gecko-associated cases across 36 states — but detection technology is only as effective as the prevention infrastructure alongside it.

The January 2025 GAO audit (GAO-25-107606) found critical shortfalls: FSIS had not updated its Campylobacter pathogen standards since 2018 or earlier; poultry contamination rates worsened by 22% against a 4% reduction target; and the Office of Management and Budget confirmed no plans exist for a national food safety strategy — despite the GAO flagging fragmented multi-agency oversight as a high-risk issue every year since 2007. Nearly two decades without resolution.

Salmonella Economic Burden in the US | Cost Statistics (2025)

Sources: USDA Economic Research Service, Cost Estimates of Foodborne Illnesses (Hoffmann et al., 2025); US PIRG Education Fund, Food for Thought 2025; CDC Foodborne Illness Burden Estimates (April 2025); CIDRAP Foodborne Disease Coverage, 2025.

Salmonella’s $17 billion annual economic toll makes it the single most costly foodborne pathogen in the United States — roughly 23% of the entire $74.7 billion US foodborne illness economic burden. This cost calculation encompasses medical treatment expenses, lost wages, long-term health sequelae such as reactive arthritis and irritable bowel syndrome, and the economic value of premature deaths.

The tripling of hospitalizations and deaths from food-related outbreaks between 2023 and 2024 — 257 additional hospitalizations and 11 additional deaths in a single year — adds a concrete recent dimension to these aggregate figures. When 98% of all 2024 outbreak illnesses traced back to just 13 outbreak events — the vast majority involving Listeria, Salmonella, or E. coli — the case for targeted, high-intensity prevention efforts around these specific pathogen-food combinations becomes fiscally undeniable.
