Oyster Salmonella Outbreak Reaches 53 Cases in 18 States

A multistate Salmonella outbreak linked to raw oysters harvested in Virginia has prompted a product recall and an investigation by federal and state health officials, with authorities reporting different case totals as of October 20, 2026. The Virginia Department of Health counted 53 illnesses across 18 states, while the Centers for Disease Control and Prevention (CDC) identified 27 infections across 12 states linked to oysters harvested by Little Wicomico Oyster Company.

The CDC and the U.S. Food and Drug Administration (FDA) announced their investigation on October 19, identifying the Little Wicomico River harvest area in Northumberland County, Virginia, as the source associated with the federal outbreak cluster. The CDC reported that illnesses began between May 29 and September 14, 2026. Five of 21 patients with available hospitalization information had been hospitalized, and no deaths had been reported.

The Virginia Department of Health's higher total included 53 Salmonella Telelkebir illnesses reported across 18 states as of October 14, according to Marler Blog. The state described the 27 cases tracked by federal officials as a genomic subgroup within its larger count. The available reports did not establish whether the remaining 26 patients were infected by the same strain.

Investigators interviewed 13 people in the federal cluster, and 10 said they had eaten raw oysters. Traceback information was available for seven patients, whose records identified oysters from Little Wicomico Oyster Company as a common source. A sample collected by Pennsylvania officials at a distributor tested positive for Salmonella, but sequencing to determine whether it matched the outbreak strain remained pending, according to information published by Marler Clark.

On October 9, Little Wicomico Oyster Company, based in Heathsville, Virginia, recalled shellstock oysters harvested from the Little Wicomico River and Little Wicomico River Lower between September 18 and October 8, 2026. The FDA said the products had been distributed to restaurants and retailers in California, Colorado, Connecticut, the District of Columbia, Florida, Georgia, Illinois, Maryland, Missouri, North Carolina, New Jersey, Nevada, New York, Pennsylvania, Texas and Virginia. Further distribution was possible.

The Virginia Department of Health closed the affected downstream harvesting area from October 9 through November 7. The company stopped harvesting in the affected area and cooperated with investigators. The FDA advised businesses not to sell or serve the recalled oysters and instructed consumers not to eat them.

Virginia's recall notice asked receiving states to verify that distributors had ceased handling the affected products. However, the federal notices did not publish a complete list of individual retailers that received the oysters.

Georgia's Department of Agriculture separately identified recalled oysters sold at Publix under the product name “James River Oysters.” Its notice listed a purchase window from September 27 through October 14, 2026, and instructed consumers to discard the product and not eat it. The notice did not identify specific store locations or establish when the retailer received the recall notification.

William Marler, managing partner of Marler Clark, said the outbreak raised questions about the contamination source and its relationship to an earlier incident involving the same Salmonella serotype.

“Salmonella is not a marine organism the way Vibrio is,” said William Marler, managing partner of Marler Clark.

Marler said contamination could enter oysters through sewage, septic drainage, agricultural runoff or wildlife. He also noted that the affected harvest area had been closed and the remaining products recalled, while emphasizing that the reported illnesses began before the recalled harvest period.

“When it is in an oyster, it got there from sewage, septic drainage, farm runoff or wildlife. Virginia and the company did the right thing by closing the river and recalling what was still in the market, but every one of the 27 reported illnesses began before the first recalled harvest date. The people who got sick this summer deserve to know where the contamination came from, and whether this is the same strain that sickened 80 people in last year’s oyster outbreak.”

The current investigation follows another Salmonella Telelkebir outbreak associated with raw oysters. The CDC closed that investigation on February 24, 2026, after 80 people across 23 states became ill; 34 of 68 patients with hospitalization information had been hospitalized. Investigators did not identify a single common oyster source, and no product recall resulted from that earlier outbreak.

Federal officials cautioned that the current case count could increase because many people recover without medical care and never undergo testing. The CDC also said it generally takes three to four weeks to determine whether an illness is connected to an outbreak, meaning recently infected people might not yet appear in the published totals.

Salmonella infection can cause fever, diarrhea, abdominal cramps and vomiting, with symptoms typically beginning six hours to six days after exposure, according to the CDC. Children younger than 5, adults 65 and older, and people with weakened immune systems face a greater risk of severe illness.

The CDC and FDA continued to track the 27 infections identified in their investigation, while Virginia's broader count remained 53 cases across 18 states in its October reporting.
