Oyster and clam harvesting has been shut down on a stretch of the Little Wicomico River in Northumberland County after state health officials traced a Salmonella outbreak in Pennsylvania back to shellfish pulled from those waters. Virginia health officials closed the river to harvesting on Friday, just eight days into the state's new oyster season, after an epidemiological link connected the illnesses to oysters harvested there.
According to WRIC ABC 8News, the Pennsylvania outbreak has sickened at least five people so far, per the Virginia Department of Health. The agency's Emergency Condemnation order #010A, dated and effective October 9, closes downstream waters of the Little Wicomico River between a specific set of coordinates, according to the Virginia Department of Health. The closure runs through November 7.
State officials said the move was made out of an abundance of caution and in direct conformance with recommendations from the U.S. Food and Drug Administration, the health department confirmed Friday. Per the same report, crabs and finfish can still be harvested from the affected waters during the closure, and shellfish within the closure zone are being actively tested. Officials also stressed that the harvesting closure has no impact on drinking water.
A Second Closure Hits Nearby Waters
The Little Wicomico closure isn't the only one in the region right now. The health department issued a second emergency shellfish closure on the same day, Emergency Condemnation #005-083B, temporarily barring harvesting in portions of Lower Machodoc Creek in nearby Westmoreland County through October 29. The overlapping orders mean two Northern Neck waterways are under shellfish condemnation simultaneously this fall.
The state's legal authority to act this quickly comes from the Code of Virginia. Under Section 28.2-809, the State Health Commissioner can close shellfish growing grounds without a hearing whenever substantial evidence of pollution exists, while Section 28.2-810 makes it illegal to harvest, store, or transport shellfish from condemned areas without a special permit from the Marine Resources Commission.
Timing Collides With Peak Harvest Season
The shutdown lands awkwardly for local watermen. Virginia's 2026–2027 public oyster harvest season officially opened across public grounds on October 1, meaning the Little Wicomico closure arrived just over a week into the fall season, according to Virginia Marine Resources Commission notices. The state's public oyster grounds produce roughly 250,000 bushels annually, backed by a replenishment program that the commission says pours between $4 million and $10 million a year into reef maintenance and shell planting.
The economic stakes extend well beyond the public fishery. Direct farm sales for Virginia's shellfish aquaculture industry reached $81 million in 2024, a 52% jump from $53 million in 2018, according to a survey released in November 2025 by William and Mary's Batten School and the Virginia Institute of Marine Science. Virginia ranks first on the East Coast for Eastern oyster production and first nationally in hard clam aquaculture, per the institute.
Food Safety Concerns
The outbreak has renewed attention to food safety concerns associated with oysters.
WRIC ABC 8News reported that it has reached out to Pennsylvania health officials and the CDC for more information and plans to provide an update when possible. It remains unclear whether further testing will isolate Salmonella directly in river shellfish or water samples, or whether a specific pollution source will be identified.
The Little Wicomico closure follows a rough stretch for Virginia's shellfish industry. Hoodline reported this week that a separate Eastern Shore oyster farm lost nearly its entire harvest to toxic algae, with the farm salvaging about 10% of its baskets. Virginia officials have also linked Pennsylvania Salmonella cases to oysters harvested from the Little Wicomico River.
