Virginia health officials closed part of the Little Wicomico River to oyster and clam harvesting on Oct. 9 after an epidemiological link connected shellfish from the area to a Pennsylvania Salmonella outbreak. At least five people have been sickened, according to the Virginia Department of Health; the closure runs through Nov. 7 while shellfish are tested.

Virginia health officials closed part of the Little Wicomico River to oyster and clam harvesting on Oct. 9 after an epidemiological investigation linked oysters taken from the river to a Salmonella outbreak in Pennsylvania. At least five people have been sickened, the Virginia Department of Health said, and shellfish from the affected waters are being tested.

The state’s Emergency Condemnation Order No. 010A applies to downstream waters within a specified section of the river in Northumberland County. The closure is scheduled to last through Nov. 7. The order makes it illegal to harvest, store or transport shellfish from the condemned area without a special permit from the Virginia Marine Resources Commission.

The department said officials acted out of an abundance of caution and in accordance with recommendations from the U.S. Food and Drug Administration. It said crabs and finfish may still be harvested from the affected waters during the closure, and that the restriction does not affect drinking water. Shellfish in the closure zone are undergoing active testing.

Virginia also announced a separate emergency shellfish closure on Oct. 9 in portions of Lower Machodoc Creek in Westmoreland County. That restriction runs through Oct. 29. The supplied report does not connect that closure to the Pennsylvania outbreak, so the two actions should not be treated as having the same cause.

How the Closure Affects Harvesting

The closure blocks commercial or recreational shellfish harvesting in the defined river area during the early part of Virginia’s public oyster season. The state season opened on Oct. 1, meaning the Little Wicomico restriction came just over a week later. For harvesters, the order is a direct limit on where shellfish can be taken, stored or transported; seafood consumers should check the source of shellfish rather than assume that all oysters or clams are affected.

Salmonella can cause diarrhea, abdominal cramps and fever, with symptoms typically appearing 12 to 72 hours after exposure, according to the source material. Most otherwise healthy adults recover within four to seven days, but severe diarrhea can require hospitalization. Infants, older adults, pregnant people and people with weakened immune systems face a greater risk of serious illness. Contaminated food may not look, smell or taste spoiled.

Anyone who ate clams from the affected area and develops symptoms should seek medical advice and mention the possible shellfish exposure. The source advises that specific tests are needed to diagnose salmonellosis, and symptoms can resemble other illnesses.

Virginia’s Fall Oyster Season

Virginia’s 2026–2027 public oyster season opened across public grounds on Oct. 1, according to notices from the Virginia Marine Resources Commission. The state’s public oyster grounds produce about 250,000 bushels a year, and the commission’s replenishment program invests between $4 million and $10 million annually in reef maintenance and shell planting, according to the supplied report.

The Little Wicomico action followed the investigation into illnesses in Pennsylvania. The reported connection is an epidemiological link between the outbreak and oysters harvested from the river; the material provided does not say that testing has definitively identified the source of contamination. The closure is a preventive measure while authorities assess shellfish from the affected waters.

“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 Testing Has Yet to Establish

The supplied information does not identify the affected patients, when they became ill, or whether any were hospitalized. It also does not give the number of shellfish samples collected or report laboratory results confirming contamination in the river. The connection to oysters is described as epidemiological; a definitive source confirmation is not provided.

Officials have not said whether the closure will end early, be extended, or change after testing. The report also does not state whether any product recall or public notice about shellfish already harvested from the area has been issued. The Lower Machodoc Creek restriction is reported separately, with no stated link to the Pennsylvania illnesses.

Testing and the Nov. 7 Deadline

Virginia health officials are testing shellfish from the Little Wicomico closure zone. The restriction is due to remain in place through Nov. 7; officials may provide further information or revise the order as results and outbreak findings develop. Harvesters should follow the condemnation order and check with the Virginia Marine Resources Commission or health department for any changes before taking shellfish from the area.

The separate Lower Machodoc Creek closure is scheduled to run through Oct. 29. No later update is included in the available report, so the status of either closure beyond its stated end date is not confirmed.

Can people still harvest other seafood in the area?

According to the Virginia Department of Health, crabs and finfish may still be harvested from the affected waters during the closure. The ban applies to shellfish, including oysters and clams, unless a special permit is granted.

What should someone do after eating shellfish from the area?
