A recent salmonella outbreak has been linked to raw oysters, with 64 people across 22 states falling ill. This alarming situation has led to at least 20 hospitalizations, but thankfully, no deaths have been reported so far. The Centers for Disease Control and Prevention (CDC) issued a warning on December 23, 2025, highlighting the ongoing outbreak and its potential impact.
The CDC's investigation revealed that a significant number of those affected had consumed raw oysters in the week prior to their illness. In fact, three-quarters of the 27 patients interviewed reported eating raw oysters. This has raised concerns, as the hospitalization rate for this outbreak is higher than usual for salmonella cases linked to oysters.
The CDC and the U.S. Food and Drug Administration are working together to identify a common source of the contaminated oysters. However, no recall notices have been issued yet. To reduce the risk of food poisoning, the CDC strongly advises cooking raw oysters before consumption.
Salmonella, a type of bacteria, resides in the intestinal tracts of humans and animals, causing an illness known as salmonellosis. The CDC emphasizes that people can become infected through various means, including eating contaminated food, drinking contaminated water, or coming into contact with animals, their feces, or their living environments.
Symptoms of salmonellosis typically manifest between six hours and six days after infection and can include watery diarrhea, fever, and stomach cramps. Less common symptoms are nausea, vomiting, headache, and loss of appetite. Most people recover from salmonellosis within four to seven days without treatment. However, in some cases, the illness can be severe enough to require hospitalization. Treatment options include staying hydrated and, in severe cases, anti-diarrheal medication or antibiotics.
The CDC warns that certain groups, such as children under five, adults aged 65 and older, and individuals with weakened immune systems, are at a higher risk of developing severe illness from salmonella. Salmonella bacteria are a significant cause of foodborne illness in the U.S., leading to hospitalizations and, in some cases, death. Despite this, the CDC estimates that cases are underreported, with only one in every 30 infections being diagnosed.
This outbreak serves as a reminder of the importance of food safety and the potential risks associated with consuming raw or undercooked foods. It also highlights the ongoing challenge of foodborne illnesses and the need for continued public health efforts to prevent and control such outbreaks.
