Raw oysters from a single company have been linked to a Salmonella outbreak across multiple states in the US. At least 27 people have been sickened in 12 states and five hospitalised, according to the US Centers for Disease Control and Prevention (CDC). No deaths have been reported so far.The outbreak has been pinned down to oysters harvested by Little Wicomico Oyster Company from the Little Wicomico River in Virginia. The company voluntarily recalled oysters harvested between September 18 and October 8, 2026. The river was temporarily closed to shellfish harvesting.Pennsylvania has reported eight infections, becoming the state with the highest number of cases currently, followed by New York with four and Virginia with three. The recalled oysters were distributed to restaurants and retailers in 16 states and Washington, DC, and may have reached other locations.Oysters That Appear Fresh Can Still Make You SickContaminated shellfish may not always show signs of spoilage. Therefore, the US Food and Drug Administration (FDA) warns - “Food containing Salmonella may look, smell, and taste normal.”Oysters can become contaminated with harmful bacteria in the environment where they grow. Eating them raw or undercooked means the bacteria may survive and cause infection. Their appearance, smell and taste cannot reliably establish whether they are safe to eat.The CDC's investigation found that 10 of the 13 people interviewed about their food exposure had eaten raw oysters before becoming ill. Investigators also found that the oysters eaten by several affected people shared a common source, supporting the link to the Virginia harvest area.Also read: FDA Expands Recall Of Frozen Berries After E.

Many people recover within four to seven days without treatment, but some may develop severe illness and need medical care. It can become serious in young children, older adults aged 65 and above and people with weak immune systems. The bacteria can occasionally enter the bloodstream and cause more severe infections.The CDC has warned that the actual number of infections may be higher than reported because some people recover without seeking medical care or getting tested.Also read: Daily Vaping In The US Surged 230%; Nearly 50% Of Young Adult Daily Vapers Used High-Nicotine E-Cigarettes: StudiesWhat Should Consumers Do?
