No, canned sardines are not raw; they are fully cooked during the canning process, which involves cleaning, smoking or frying/steaming, and then pressure-cooking in the sealed tin, making them ready to eat straight from the can. The bones are softened from the cooking, making them edible and a source of calcium.
Canned sardines are a nutritious, low‐mercury choice during pregnancy when consumed in moderation, with attention to sodium content and can integrity. They contribute valuable omega‐3s, calcium, vitamin D, and protein that support fetal development.
Not only are the guts removed before being canned, the bones have been softened by the cooking process which makes them edible as well.
If you are curious about diving into the world of tinned fish, you may have some questions like, "Are those small containers of canned fish actually cooked?" The answer is yes! In fact, all canned food is cooked, and you can even eat them straight out of the tin.

Sardines and salmon
The omega-3 fatty acids help with fertility, but females hoping to conceive should avoid foods high in mercury — it can reduce fertility and cause abnormal menstrual cycles. Finding the right balance of high omega-3 fatty acids and low mercury can be challenging, but it's worth it.
Sardines are also rich in essential nutrients that reduce inflammation, support bone health, and improve cardiovascular outcomes. Unlike fish oil supplements, sardines provide nutrients in a whole-food form that is easily accessible and well-tolerated.
Canned sardines are often a healthier choice than canned tuna, the experts note. While both are high in protein, sardines are more nutrient-dense. Sardines have a higher combined omega-3 (DHA and EPA) content than tuna fish, says Largeman-Roth. Sardines are also lower in mercury than tuna.
Canned sardines
Sardines are canned in many different ways. At the cannery, the fish are washed, their heads are removed, and then smoked or cooked, either by deep-frying or by steam-cooking, after which they are dried.
Salted sardines have high levels of Hg, Pb, As, and Cd compared with raw and canned ones. Arsenic levels exceeded the permissible limit in all types of sardines analyzed. Salting increases the heavy metals in fish, while cooking has no significant effect.
Pre-cooked pasta in sauce is one of the unhealthiest canned foods. While they might be tasty meals, the reason they have that addictive flavour is due to high levels of sugar and salt. For example, a can of Heinz Alphaghetti contains 1,490 mg of sodium and 18 g of sugar.
Scombroid Fish Poisoning
An allergy-like reaction that occurs after eating fish that has high levels of histamine because it has not been properly stored or processed. This is more common in fish which turns brown upon cooking. This including mackerel, tuna, king fish, herring, sardines, marlin, anchovies and bluefish.
