Salmonella Outbreak Linked to Raw Oysters - Centers for Disease Control and Prevention | CDC (.gov)

The recall applies to whole, shellstock oysters harvested from the Little Wicomico River in Virginia. It includes oysters collected from September 18 through October 8, 2026. The scope matters because oysters from different growing areas are tracked separately, so location and harvest date identify which products may be affected.

The affected locations are listed as Little Wicomico River, VA, and Little Wicomico River Lower, VA. For example, a shellstock oyster harvested there on October 3 falls within the recall. An oyster harvested from another Virginia growing area does not fall within this specific recall.

Little Wicomico Oyster Company voluntarily recalled the oysters on October 9 and stopped harvesting from the affected area. The Virginia Department of Health temporarily closed that harvest area as a precaution. Public health officials are involved, while oysters from other Virginia growing areas remain outside the recall.

Salmonella is bacteria that can cause an infection after a person swallows it. The article identifies diarrhea, fever, and stomach cramps as the most common symptoms. The illness matters because some infections become severe, especially in young children, older adults, and people with weakened immune systems.

A person with Salmonella may develop diarrhea and stomach cramps along with a fever. Symptoms usually start 6 hours to 6 days after swallowing the bacteria. For example, someone who ate contaminated oysters could feel well at first, then develop digestive symptoms several hours or days later.

Most people recover without treatment after 4 to 7 days. However, severe diarrhea, prolonged vomiting, bloody diarrhea, or dehydration can require medical care. The article advises contacting a healthcare provider promptly for specific warning signs, including a fever higher than 102°F with diarrhea.

Consumers should not eat any recalled oysters. They should throw them away or return them. This prevents people from consuming a product included in the recall. Businesses have the same responsibility: restaurants and retailers must not sell or serve the affected oysters.

Any item or surface that touched the oysters should be cleaned. The article recommends hot, soapy water or a dishwasher for consumer items. Businesses should wash and sanitize equipment and surfaces that may have contacted the oysters. For example, a cutting surface, container, or utensil used with the product should not be used again until it has been cleaned.

These steps address both the food and possible contact areas. Little Wicomico Oyster Company stopped harvesting from the affected area and is cooperating with public health officials. Consumers should also seek medical advice for serious symptoms, such as bloody diarrhea or dehydration.

Salmonella symptoms usually begin 6 hours to 6 days after a person swallows the bacteria. This delay means someone may not feel sick immediately after eating contaminated oysters. The timing can make it important to remember recent foods if symptoms later appear.

The article lists diarrhea, fever, and stomach cramps as typical symptoms. For example, a person could eat oysters one day and develop diarrhea or stomach cramps several hours later, or symptoms could begin several days afterward. The article does not give a more precise individual prediction for when symptoms will start.

Most people recover without treatment after 4 to 7 days. Illness may be more serious for children younger than 5, adults 65 and older, and people with weakened immune systems. Medical care is important for bloody diarrhea, persistent diarrhea, severe vomiting, dehydration, or diarrhea with a fever higher than 102°F.

Severe Salmonella illness is more likely in children younger than 5, adults 65 and older, and people with weakened immune systems. The article notes that these groups may need medical treatment or hospitalization. Their higher risk makes prompt attention to symptoms especially important.

Warning signs include diarrhea with a fever higher than 102°F, diarrhea lasting more than 2 days without improvement, and bloody diarrhea. Another urgent sign is vomiting so much that liquids cannot be kept down. These symptoms can signal a more serious illness or worsening condition.

Dehydration is also a medical warning. Signs listed in the article include not peeing much, a dry mouth and throat, and dizziness when standing up. Anyone with these urgent symptoms should call a healthcare provider right away. Most people recover in 4 to 7 days, but these warning signs require faster action.

Food recalls can be limited to products connected to a particular harvest area and time. Here, Little Wicomico Oyster Company recalled oysters harvested from the Little Wicomico River and Little Wicomico River Lower during September 18 through October 8, 2026. The location-based scope matters because not every Virginia oyster-growing area is included.

For example, oysters harvested from an affected Little Wicomico River area on September 25 fall within the recall. Oysters harvested from another Virginia growing area do not. The article specifically states that oysters from other Virginia growing areas are not part of this recall.

The Virginia Department of Health temporarily closed the Little Wicomico River harvest area as a precaution. The company stopped harvesting there and is cooperating with public health officials. These actions focus the response on the identified area while leaving other Virginia growing areas outside this specific recall.

Raw oysters can transmit bacteria because they are eaten without cooking, so bacteria present in the oyster may remain. Oysters take in surrounding water while feeding, which is a general reason harvest-water safety matters. The article identifies Salmonella as bacteria that can cause illness, but it does not explain how contamination occurred in this recall.

Monitoring can test or track harvest waters and oyster safety, while sanitation reduces contact with contaminated food or surfaces. A temporary closure stops harvesting from an area while officials respond. In this case, the Virginia Department of Health temporarily closed the Little Wicomico River harvest area as a precaution.

The company also stopped harvesting there and cooperated with public health officials. Consumers and businesses must wash touched items and surfaces, using hot soapy water, a dishwasher, or sanitation procedures. These measures reduce further exposure, while the recall removes affected oysters from eating and selling.
