A Salmonella outbreak linked to raw oysters has affected 64 people across 22 states, including three cases in South Carolina, with 20 hospitalizations reported but no deaths.​
Outbreak Scope
Illnesses occurred from late June to late November 2025, with patients ranging in age from 10 to 76 and a median age of 52. Of 27 interviewed patients, 74% reported eating raw oysters in the week before symptoms began, far exceeding typical rates. States like Pennsylvania (10 cases), New York (7), New Jersey, and Virginia (6 each) saw the highest numbers, alongside nearby areas such as North Carolina, Georgia, Florida, and South Carolina.​
Symptoms and Risks
Common symptoms include diarrhea, fever above 102°F, stomach cramps, vomiting, and dehydration, appearing 6 hours to 6 days after consumption and lasting 4-7 days for most. Vulnerable groups—children under 5, adults over 65, and those with weakened immune systems—face higher hospitalization risks, which exceeds norms for similar outbreaks. Seek medical care for severe or persistent symptoms.​
Investigation Status
The CDC and FDA are tracing oyster supply chains but have not identified a single source or issued recalls yet. Cooking oysters thoroughly reduces contamination risks from bacteria like Salmonella.
