Health officials warn of a Salmonella Telelkebir outbreak linked to raw oysters. 64 people across 22 states have fallen ill. Learn safety tips and precautions.
Health authorities are issuing warnings about a Salmonella outbreak connected to raw oysters that has affected 64 people across 22 states in the United States. This outbreak, caused by a rare strain known as Salmonella Telelkebir, has resulted in 20 hospitalizations, though no deaths have been reported. The Centers for Disease Control and Prevention (CDC) are leading the investigation in collaboration with the U.S. Food and Drug Administration (FDA) and state health departments.
Salmonella is a type of bacteria that can cause foodborne illness, commonly resulting in diarrhea, fever, abdominal cramps, and vomiting. While many strains of Salmonella exist, the Telelkebir strain is particularly rare. Most healthy individuals recover without medical intervention, but vulnerable populations, including young children, older adults, and people with weakened immune systems, may experience severe illness.
The CDC reports that this strain has been detected through PulseNet, a national network for tracking foodborne illness. Genetic testing of the samples from infected patients indicates a high likelihood that all infections stemmed from the same contaminated food source. Importantly, lab testing also revealed no evidence of antibiotic resistance in 59 patients tested, which is a positive sign for treatment options.
According to CDC data, illnesses associated with this outbreak occurred between June 21 and November 28, 2025. The infections have been reported in 22 states, with Pennsylvania reporting the highest number at 10 cases. New York reported seven cases, while New Jersey and Virginia each reported six. The wide geographic spread suggests that contaminated oysters were distributed across multiple regions.
Interviews with patients revealed that 74 percent of them had eaten raw oysters shortly before developing symptoms. In comparison, only 1.6 percent of the general population typically consumes raw oysters, strongly indicating that oysters are the likely source of this outbreak.
The affected individuals range in age from 10 to 76, with a median age of 52. Approximately 65 percent of the patients were male. Among those who reported their race and ethnicity, 85 percent identified as white, 12 percent as Black, and 2 percent as Native Hawaiian or other Pacific Islander. These figures help public health officials understand the demographics impacted by the outbreak, though the bacteria can infect anyone who consumes contaminated seafood.
Salmonella infection can manifest in several ways. Common symptoms include:
Symptoms usually begin six hours to six days after consuming contaminated food. While most healthy individuals recover within a week, severe cases may require hospitalization due to dehydration or complications. The CDC urges anyone experiencing these symptoms after eating raw or undercooked seafood to seek medical care immediately. Reporting the illness to local health authorities is also essential to help track the outbreak.
Health officials stress that raw oysters can harbor harmful bacteria throughout the year. To reduce the risk of foodborne illness, the CDC and FDA recommend:
Consumers should also stay informed about recalls and public health alerts related to seafood. Regularly checking the FDA and CDC websites can help ensure you are aware of any contaminated products on the market.
The CDC is working with the FDA and state health departments to trace the source of the contaminated oysters. The use of PulseNet has allowed scientists to confirm that the genetic fingerprint of the bacteria matches across multiple patients, indicating a single source of contamination.
Investigations into the exact origin of the oysters are ongoing. Factors such as harvesting locations, handling practices, and storage conditions will be examined. Officials note that the reported cases likely underestimate the true extent of the outbreak, as many people recover without medical care, and recent cases may not yet appear in official counts.
Salmonella outbreaks tied to seafood have significant public health and economic impacts. Restaurants, seafood distributors, and oyster farms may face increased scrutiny and potential financial losses. Public health authorities emphasize that adherence to proper handling, storage, and cooking guidelines is crucial to prevent future outbreaks.
The FDA regularly monitors seafood safety through inspections, sampling, and recalls when necessary. Consumers are encouraged to purchase oysters from reputable sources and verify that seafood has been handled according to safety standards.
The CDC recommends that anyone who has eaten raw oysters recently monitor for symptoms. If any signs of illness appear, individuals should:
Public health communication is key during outbreaks to prevent further spread. By following official guidelines, the risk of illness can be minimized.
