Virginia shut down oyster and clam harvesting on a stretch of the Little Wicomico River on Oct. 9, after state health officials traced a Salmonella outbreak in Pennsylvania that has sickened at least five people back to shellfish pulled from those waters.

The closure landed just eight days into Virginia's 2026–2027 public oyster harvest season, which opened Oct. 1 across public grounds. The Virginia Department of Health issued Emergency Condemnation order #010A, closing downstream waters of the Little Wicomico River in Northumberland County between a specific set of coordinates. The closure runs through Nov. 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.

What does the closure cover?

The order makes it illegal to harvest, store, or transport shellfish from the condemned area without a special permit from the Marine Resources Commission. Several carve-outs remain in effect:

• Crabs and finfish can still be harvested from the affected waters during the closure.
• Shellfish within the closure zone are being actively tested.
• The closure has no impact on drinking water, officials stressed.

The Little Wicomico closure is not the only emergency action in the region. On the same day, Oct. 9, the health department issued a second emergency shellfish closure — Emergency Condemnation #005-083B — temporarily barring harvesting in portions of Lower Machodoc Creek in nearby Westmoreland County through Oct. 29.

What's at stake for Virginia's oyster supply?

Virginia's public oyster grounds produce roughly 250,000 bushels annually, according to Virginia Marine Resources Commission notices. The state backs that output with a replenishment program that pours between $4 million and $10 million a year into reef maintenance and shell planting.

A closure spanning from Oct. 9 through Nov. 7 removes part of that harvest capacity during the opening weeks of the fall season, when oyster demand builds toward year-end menus.

What operators and consumers should know about Salmonella

Food contaminated with Salmonella bacteria does not usually look, smell, or taste spoiled. Infants, children, seniors, and people with weakened immune systems face higher risk of serious illness.

Anyone who has eaten clams from the affected area and developed symptoms should seek medical attention and tell their doctors about the possible Salmonella exposure, because special tests are necessary to diagnose salmonellosis. Symptoms can include diarrhea, abdominal cramps, and fever within 12 to 72 hours after eating contaminated food. Healthy adults are usually sick for four to seven days, though severe cases may require hospitalization.

Some people become infected without symptoms but can still spread the infection to others.

Officials have not announced a reopening date beyond the Nov. 7 expiration of the order, and continued testing of shellfish in the closure zone will determine whether harvesting resumes on schedule.
