The U.S. Food and Drug Administration said the cases of norovirus are linked to quick-frozen oysters. It’s now urging all restaurants and stores that sell frozen, raw half-shell oysters to check their freezers for specific information regarding their origin.

The warning applies to oysters processed by JBR (KR 15 SP) in Tongyeongsi, Republic of Korea on Nov. 27, 2023 as well as this past Jan. 4 and Feb. 15.

The release by the county said the oysters may be labeled “Amazing Sea Brand.”
