A multistate outbreak of Salmonella infections linked to raw oysters has sickened 64 people across 22 states, according to the Centers for Disease Control and Prevention (CDC). Of those infected, 20 have been hospitalized, but no deaths have been reported. The hospitalization rate is higher than in other Salmonella outbreaks related to oysters.

State and local public health officials interviewed 27 affected individuals, with 20 (74%) reporting they ate raw oysters in the week before becoming ill. The CDC and Food and Drug Administration (FDA) are working to determine if a common source of oysters is involved. No product recall has been announced at this time.

The CDC advises that raw oysters can harbor harmful germs at any time of year. Thorough cooking is recommended to reduce the risk of foodborne illness. Hot sauce and lemon juice do not kill bacteria, and contamination cannot be detected by appearance.

Symptoms of Salmonella infection typically include diarrhea, fever, and stomach cramps, appearing within 6 hours to 6 days after exposure and lasting 4 to 7 days. Most people recover without treatment, but children under 5, older adults, and those with weakened immune systems may require hospitalization.
