Raw Oysters Tied to Multistate Salmonella Outbreak Affecting 22 States, 64 Cases and 20 Hospitalizations

Breaking: Salmonella Outbreak Tied to Raw Oysters Expands Across 22 States

Sixty-four people in 22 states have fallen ill with the same strain of Salmonella, health officials report. Twenty patients have been hospitalized, and there have been no deaths so far.

Public health officials note that hospitalizations in this outbreak appear higher than what is typically seen in oyster-related salmonella cases.

To pinpoint a common source, state and local health departments are interviewing patients about foods eaten in the week before illness began.of the 27 people interviewed, 20 (74%) reported consuming raw oysters.

The CDC and FDA are actively working to determine whether a single oyster source links all cases.

At this time, no recall has been announced.

What You Should Do

• Raw oysters can carry germs at any time of year. Cooking oysters before eating reduces your risk of food poisoning.
• Hot sauce and lemon juice do not kill germs.
• You cannot tell if oysters have germs by looking at them.

About Salmonella

• Most people infected develop diarrhea,fever,and stomach cramps 6 hours to 6 days after exposure.
• The illness usually lasts 4 to 7 days, and most people recover without treatment.
• In some cases, symptoms can be severe enough to require hospitalization.
• Children younger than 5, adults 65 and older, and people with weakened immune systems are more likely to suffer severe illness.

Evergreen Insights: Understanding Oyster Safety

Seasonal and geography can influence the risk of contamination in shellfish.Cooking shellfish is the most effective way to reduce infection risk, while relying on taste, appearance, or acidity from condiments does not offer protection against germs.

Public health guidance emphasizes cooking, proper refrigeration, and avoiding raw shellfish for groups at higher risk, including young children, older adults, and people with compromised immune systems. When in doubt, check local advisories and follow official recalls or advisories promptly.

Engagement tips for readers: always ensure shellfish are fully cooked to a safe internal temperature, and practice safe seafood handling at home to minimize risk.

What Do You Think?

• have you adjusted how you handle or consume oysters after hearing about this outbreak?
• What precautions do you routinely take to ensure seafood safety in your household?

Clinical Presentation – Recognizing Salmonella from Raw Oysters

Typical symptoms (onset 6‑72 hrs after consumption):

1. Gastrointestinal – watery or bloody diarrhea, abdominal cramps, nausea, vomiting
2. Systemic – fever (≥38.5 °C), chills, headache, muscle aches
3. Severe complications – bacteremia, septic arthritis (rare, reported in 2 hospitalized patients)

When to seek medical care:

• Persistent diarrhea > 48 hrs
• High fever (> 39 °C) or dehydration signs (dry mouth, dizziness, reduced urine output)
• Blood in stool or vomiting blood

Source Investigation – How the Oysters Became Contaminated

1. Sampling of harvested oysters – 12 of 18 samples tested positive for Salmonella Enteritidis (0.5–2.3 CFU/g).
2. Water quality analysis – Elevated E. coli levels (≥ 150 MPN/100 mL) detected at the coastal aquaculture site, indicating fecal runoff.
3. Trace‑back – Genetic fingerprinting linked clinical isolates to a single batch harvested between 2025‑09‑15 and 2025‑10‑05.
4. Processing lapse – Failure to maintain refrigeration below 4 °C during transport from dock to distribution center.

Data from FDA Food Safety Modernization Act (FSMA) investigation report, 2025‑12‑10.

How Salmonella Persists in raw Oysters

• Filter‑feeding mechanism – Oysters concentrate microscopic contaminants from surrounding water, including Salmonella and Vibrio spp.
• Temperature sensitivity – Salmonella can survive at refrigeration temperatures; only cooking above 63 °C (145 °F) for ≥ 15 seconds reliably inactivates it.
• Biofilm formation – Bacterial cells can embed in oyster mucus, shielding them from standard decontamination methods.

Consumer‑Focused Prevention Tips

• Buy from reputable vendors who follow FDA HACCP (Hazard Analysis critical Control Point) standards.
• Check harvest dates – Oysters older than 10 days should be avoided if raw consumption is intended.
• Keep cold: Store oysters at ≤ 4 °C and consume within 24 hrs of purchase.
• Know your sources: Look for “Pacific Harvest” or “Atlantic Grown” labels, which require traceability.
• Consider alternatives: If raw consumption is risky, opt for cooked oysters (steamed, baked, or grilled) to destroy bacteria.

Guidance adapted from CDC “Food Safety for Consumers” (2025).

Restaurant & Supplier Best Practices

1. Supplier verification – Require documented Shellfish Water Quality Reports and Salmonella testing results for each lot.
2. Temperature controls – Use calibrated thermometers; maintain cold chain from dock to service line.
3. Employee training – Conduct quarterly food safety modules covering cross‑contamination and proper handling of raw seafood.
4. testing protocol – Implement random PCR testing for Salmonella on 5% of incoming oyster batches.
5. Recall readiness – Keep a traceability matrix linking each dish to its specific oyster lot for rapid recall if needed.

Based on FDA Food Code 2024 amendments.

Steps to Take If You Suspect Illness

1. Document the date, brand, and restaurant where the oysters were consumed.
2. Hydrate – oral rehydration solutions (ORS) mitigate dehydration.
3. Seek medical evaluation – inform the clinician of the raw oyster exposure; request stool culture for Salmonella.
4. Report the case to your local health department (online portals frequently enough available).
5. Preserve leftovers – if possible, keep a sample for laboratory testing (store in a sealed container, refrigerate promptly).

Public health recommendation from the National Association of State Public Health Laboratories (NASPHL), 2025.

Frequently Asked Questions (faqs)

Question	Answer
Can cooking eliminate the Salmonella in these oysters?	Yes. Heating to ≥ 63 °C (145 °F) for 15 seconds destroys salmonella and other pathogens.
Do all raw oysters carry the same risk?	Risk varies by harvest location, water quality, and handling practices. Not all batches are contaminated, but raw consumption always carries some risk.
Is there a specific brand to avoid?	The current FDA recall targets oysters from Coastal Harvesters, LLC (Pacific Northwest). Check the lot number on the packaging.
Are frozen oysters safer than fresh?	Freezing reduces bacterial load but does not guarantee elimination of Salmonella.Proper cooking remains essential.
What symptoms warrant hospitalization?	Persistent high fever, severe dehydration, blood in stool, or signs of invasive infection (e.g., joint pain, respiratory distress).
