Building the Future of Biodefense

Recommendation: Raw oysters and clams can be contaminated with germs at any time of year. Organizations in the United States (US) and Canada should not sell or serve the affected recalled products from Drayton Harbor Oyster Company and Lummi Indian Business Council. Anyone with these products at their workplace or home should dispose of them. People at high risk of health-related complications may wish to avoid all oyster and clam products from these businesses while this investigation is ongoing.

Situation: Washington recalled oysters and clams linked to a norovirus outbreak that sickened at least 11 people. The recalled oysters, from Growing Area Drayton Harbor, include all species harvested by Drayton Harbor Oyster Company (WA-1723-SS) and Manila clams harvested by the Lummi Indian Business Council (WA-0098-SS). The recall dates were from 2/13 to 3/3. Oysters were sold within Washington, while clams were distributed to multiple US states (AZ, CA, NV, NY, OR) and Canada. Distributors contacted retailers, but most of the affected shellfish have likely already been consumed. [Confidence: Very High]

Recommendation: Organizations in the United Kingdom should not sell or serve the recalled Sacor Bastides Saucisson Sec product. Anyone with this product at their workplace or home should dispose of it. People at high risk of Salmonella-related complications may wish to avoid all Sacor cured pork products while this investigation is ongoing.

Situation: The UK issued a recall notice for Bastides Saucisson Sec - 200g (best before date of 3/4/2026) due to the presence of Salmonella. The Sacor product was exclusively sold at Tesco locations. Media sources also reported 84 confirmed Salmonella Typhimurium cases detected from 1/7 to 2/11 across England, Wales, and Scotland. The cases were genetically similar, indicating a common source of contamination. Several cases were hospitalized, but no deaths have been reported. Initial investigations indicated that a higher-than-expected proportion of cases consumed cured pork products, including an imported, ready-to-eat, cured pork product, within 7 days before symptom onset. Genetic analysis is ongoing to determine if the Salmonella in the Bastides Saucisson Sec recalled product matches the Salmonella strain detected in cases. [Confidence: Very High]

Recommendation: The polio vaccine is more than 99% effective in preventing poliovirus infection. Travelers to Pakistan should verify their polio vaccination status before travel.

Situation: Pakistan confirmed its 1st wild poliovirus case of 2026 in a 4-year-old child from Sujawal district, Sindh. The next national vaccination campaign is planned for April. Poliovirus detections have declined compared to 2024 due to strong 2025 vaccination campaigns, but transmission continues in high-risk areas of Sindh and southern Khyber Pakhtunkhwa, highlighting the need for continued targeted efforts and consistent child vaccination.
