Under what condition would you REJECT a shipment of live oysters?

Rejecting a shipment of live oysters when the shells are open is critical to food safety. Open shells indicate that the oysters are likely dead. Live oysters should tightly close their shells when tapped or disturbed; an open shell demonstrates that the oyster is no longer alive, which can pose a significant health risk if consumed.

The correct decision to reject oysters with open shells is grounded in the understanding that seafood, particularly bivalves like oysters, must be alive at the point of sale to ensure they are safe for consumption. The presence of dead oysters increases the risk of contamination and potential foodborne illness.

In contrast, the conditions described in the other options would not warrant rejection. A mild ocean smell is normal for live oysters and indicates freshness, while closed shells demonstrate that the oysters are alive. Additionally, shell stock IID tags are essential for traceability and are required; their presence does not indicate an issue with the oysters.
