Canned clams are a popular shelf-stable product consumed around the world. Clams are packed into cans while raw and then heat processed to cook them. This heating process both cooks the clams and sterilizes the can, allowing the product to be shelf-stable without refrigeration. However, some people may still wonder – are canned clams actually fully cooked when you open the can? Or are they still raw on the inside?
Are canned clams cooked?
Yes, canned clams are fully cooked when you purchase them from the store. The canning process involves multiple steps that thoroughly cook the clams:
Shucking
Clams are first harvested and then shucked, removing them from their shells while still raw. The edible clam meat is separated from the shell.
Washing
The raw shucked clam meat is washed thoroughly to remove any sand or grit.
Filling
The cleaned clam meat is then put into cans. The cans are filled with either clam meat alone or clam meat plus clam juice or another braising liquid.
Sealing
The filled cans are sealed shut to prevent leakage during the cooking process.
Thermal Processing
The sealed cans are put into large pressure cookers or retorts and thermal processed. This involves cooking the sealed cans at 250°F or higher for at least 90 minutes.
This extreme heat cooks the clam meat thoroughly until it reaches an internal temperature of 185°F throughout the can. The high heat also sterilizes the contents, killing any microorganisms inside the can.
Cooling
After thermal processing, the canned clams are cooled down to room temperature. They are then labeled and ready for distribution and sale.
As you can see, canned clams go through an extensive multi-step canning process that heats them to high enough temperatures for long enough durations to fully cook the clam meat inside.
By the time a can of clams ends up on your grocery store shelf, the clams inside are already thoroughly cooked and safe to eat right out of the can.
Why are canned clams fully cooked?
Canned clams must be fully cooked as part of the canning process for two main reasons:
Food Safety
Clams and other shellfish can harbor harmful bacteria and viruses when raw, like Salmonella, Vibrio, Norovirus, and Hepatitis A. Consuming raw or undercooked shellfish comes with a high risk of food poisoning.
Heating clams to an internal temperature of at least 145°F is sufficient to kill any dangerous microorganisms that may be present. Canned clams are cooked well above this temperature to eliminate food safety risks.
Shelf Stability
Thorough cooking is also necessary to make canned clams shelf-stable. The canning process sterilizes the contents by heating them to 250°F or higher. This kills all microorganisms inside the can, preventing the growth of bacteria, mold, and other spoilage organisms.
Sterilization allows canned clams to be stored at room temperature rather than requiring refrigeration. The canned clams remain safe and shelf-stable for years until the can is opened.
If the clams were not fully cooked during canning, the cans would have to be refrigerated. There would be a risk of spoilage and foodborne illness from microorganisms surviving inside raw or undercooked clams.
How are canned clams processed differently from fresh clams?
Canned and fresh clams undergo very different preparation processes:
Fresh Clams
– Harvested live in the shell on demand.
– Sold fresh on ice or live in tank systems.
– Require refrigeration to prevent bacterial growth.
– Cooked shortly before eating.
– Safe when cooked to an internal temperature of at least 145°F.
Canned Clams
– Shucked from the shell and canned raw.
– Thermally processed at 250°F or higher for 90+ minutes.
– Fully cooked and shelf-stable without refrigeration.
– Contents sterilized to eliminate bacteria.
– Ready to eat directly from the can.
The high heat thermal processing used for canning is necessary to both cook the clams fully and sterilize the can, allowing for shelf stability and safe consumption without further cooking.
Do canned clams need to be cooked again before eating?
No, canned clams do not need to be cooked again after opening the can. The clams are already fully cooked from the canning process.
It is perfectly safe to simply open the can and eat the clams straight out of the can without any further cooking. Additional cooking would make the clams overdone and rubbery.
Canned clam products like chowders or fritters may have other ingredients added that are not fully cooked, like potatoes or batter. In those cases, you need to cook the entire dish thoroughly before consuming to make sure any raw ingredients are properly cooked.
But plain canned clams by themselves just need to be heated, not re-cooked, once opened. You can gently heat them through on the stovetop or in the microwave without damaging their tender texture.
Here are some safe ways to enjoy canned clams without cooking them again:
– Eat them straight out of the can as a cold snack or appetizer.
– Make pasta dishes by tossing canned clam meat with hot pasta. The clams will gently heat through.
– Add canned clams to salads, salsa, or chowders right before serving.
– Gently warm canned clams in chowders, fritters, or dips on the stovetop or microwave before eating.
As long as the can was sealed and not damaged, you can feel confident eating canned clams directly without any additional cooking required.
Common questions about canned clams
Here are answers to some other frequently asked questions about canned clams:
Are the clams mushy or chewy in canned form?
Properly processed canned clams should have a tender, not mushy, texture. Overcooking during canning can make the clam meat tough and rubbery. High-quality brands use careful thermal processing to preserve the natural tender bite of fresh clams.
Do I need to rinse canned clams before eating?
No, canned clams are ready to eat directly from the can once opened. Any sand or grit was removed during canning. The canning liquid is the natural clam broth. Draining or rinsing is not necessary unless you want to reduce the salt content.
Do canned clams taste fishy or salty?
Quality canned clams should taste fresh, with a mild sweetness and brininess similar to live clams. Rancid or strong fishy flavors mean the product is past its prime. To limit saltiness, look for low-sodium or no salt added varieties.
Are the shells included in canned clam products?
No, only the edible clam meat is packed into the cans. The shells are removed during the initial shucking process and not included. Any bits of shell or sand would be detected during manufacturing.
How long do canned clams last after opening?
Keep opened canned clams refrigerated and use within 3-4 days. The canning process destroys any bacteria initially present but does not prevent new bacteria from entering the can once opened.

Conclusion
Canned clams are pre-cooked during the canning process, so no additional cooking is required before eating them. The extreme high heat canning ensures the clam meat is thoroughly cooked to eliminate any foodborne illness risks. Fully cooking the clams also sterilizes the contents for long term shelf stability.
While fresh clams must be cooked immediately to at least 145°F for food safety, canned clams are ready to enjoy straight from the can. Their tender texture and mild sweet brininess make them the perfect shortcut ingredient for chowders, pastas, pizzas, and appetizers.
Stock up on canned clams for their year-round convenience, great taste, and stellar nutritional profile. Just be sure to refrigerate any leftovers and use within 3-4 days after opening. Follow basic food safety practices, and enjoy incorporating canned clams into your cooking repertoire.
