Can I eat geoduck ceviche (cooked)?
Quick Answer
Yes
Geoduck ceviche, when properly prepared and cooked, is safe to eat. However, as with any seafood, it’s important to ensure it’s fresh and handled properly to avoid foodborne illnesses.

What Is It?
Geoduck ceviche is a dish made from the raw meat of the geoduck clam, which is marinated in citrus juices until it ‘cooks’ or firms up. The geoduck is a large, edible saltwater clam native to the west coast of North America.
How to Tell
Fresh geoduck should have a clean, briny scent. The meat should be firm, not mushy, and the color should be translucent white. Any discoloration or off-putting smell is a sign of spoilage.
Why It Can Be Risky
Eating raw or undercooked seafood, including geoduck, can pose risks such as foodborne illnesses.
These can include bacterial infections like Vibrio vulnificus, or parasitic infections. People with weakened immune systems are particularly at risk.
Safe Method?
Ensure the geoduck is fresh and has been stored properly. For ceviche, marinate the geoduck in citrus juices for at least 4 hours to ‘cook’ it. Some people prefer to blanch the geoduck before making ceviche to ensure it’s fully cooked.
Safe Alternatives
If you’re concerned about eating raw seafood, you can fully cook the geoduck before making ceviche. Other shellfish, like shrimp or scallops, can also be used in ceviche.
Storage Tips
Fresh geoduck should be stored in the refrigerator and used within a few days. If you’re not using it immediately, you can freeze it for up to 3 months.
Preparation Tips
To prepare geoduck for ceviche, first clean it thoroughly. Then, slice it into thin strips and marinate it in citrus juices.
