For the lowest mercury canned tuna, choose skipjack tuna (often labeled "chunk light") and brands like Safe Catch (especially their Elite line which tests every fish), Bumble Bee Chunk Light, and Chicken of the Sea Chunk Light, as these species are smaller and have shorter lifespans, accumulating less mercury than larger tuna like albacore.

The bottom line
Choosing pole-and-line-caught light skipjack tuna is your best choice for a low mercury and sustainable option. White albacore tuna is best if you're looking for more protein and omega-3 fats with every bite.
The healthiest canned fish are small, oily varieties like sardines, mackerel, anchovies, and herring (SMASH), packed with omega-3s, protein, vitamin D, calcium (especially with bones), and lower mercury, with anchovies and sardines often topping the list for overall nutrition and lower cost; salmon is also excellent but choose smaller species like canned sockeye or chum.
Sirena tuna is considered good because of its premium quality, using pole-and-line caught yellowfin tuna, which results in a richer flavor, firm chunky texture, and lower mercury levels compared to other brands. Consumers praise its superior taste, often packed in quality oils or springwater, making it versatile for salads, sandwiches, and meals, despite being a pricier option.
Tuna, salmon, sardines, mackerel, mussels, oysters: The healthiest types of tinned fish.
You would have to eat around 25 tins (at 95g a tin) of it a week before you hit the maximum tolerable intake of mercury. For pregnant people (or people trying to get pregnant), the limit would be around 12 tins (at 95g a tin) a week. It is unlikely many consumers will reach these limits.
The concerns around daily intake stem from its mercury content. However, according to the NHS, which states a healthy, balanced diet should include at least two portions of fish a week, there's nothing there to say you can't eat tuna every day, unless you're trying for a baby, or pregnant.
Mackerel
It's an excellent substitute for tuna because it's also high in protein and loaded with omega-3 fatty acids. Compared to tuna, mackerel is often more sustainable and has lower mercury levels.
If you're counting calories and maximizing omega-3 fatty acids, then tuna in water might make a great choice. On the other hand, if moisture, flavor, and vitamin D levels are your focus, then olive oil-packed tuna might be better. Whatever tuna you choose, it's important not to go overboard for this mild-flavored fish.
Researchers from Chalmers University of Technology have come up with a novel approach to packaging canned tuna infused in the water-based solution of amino acid cysteine. It was shown to remove up to 35 percent of the accumulated mercury in canned tuna, significantly reducing human exposure to mercury via food.
Omega 3s
These are the good fats that keep your heart happy and healthy. Tuna is brimming with two types of omega-3 fatty acids, DHA and EPA, which have been linked to reduced inflammation, improved brain function, and a lowered risk of heart disease.
Canned tuna is the only seafood in some people's diets. So that's why mercury contamination is such a concern in this particular fish. Mercury is a known neurotoxin. Too much of it is harmful to children, whose bodies and brains are still growing.
Initial signs and symptoms, such as fever, chills, shortness of breath, metallic taste, and pleuritic chest pain, may be confused with metal-fume fever, which is caused by cadmium exposure. Other possible symptoms include stomatitis, lethargy, confusion, and vomiting.
If you're concerned about limiting the amount of mercury you consume, and if you've eaten no other fish during the week, Consumer Reports says up to 12 ounces a week of Bumble Bee Chunk Light, Chicken of the Sea Chunk Light, Safe Catch Wild Elite, and StarKist Chunk Light tunas are the safer choices among the products ...
There are two main kinds of canned tuna: chunk light and solid or chunk white (albacore). Mercury levels in canned white tuna, which is exclusively albacore, are almost three times higher than those found in smaller skipjack tuna commonly used in canned light tuna products.
Sirena tuna is considered good because of its premium quality, using pole-and-line caught yellowfin tuna, which results in a richer flavor, firm chunky texture, and lower mercury levels compared to other brands. Consumers praise its superior taste, often packed in quality oils or springwater, making it versatile for salads, sandwiches, and meals, despite being a pricier option.
The Best Canned Tuna, Ranked
Top 10 Tunas
Some tuna cans that say do not drain because they don't add oil, water, fillers, preservatives, and GMO soy broth. Cans that say do not drain contain only tuna or sometimes salmon. They only have natural occurring fish oils and juices and those are rich in omega threes.
In contemporary times, the family maintains control of a string of businesses including Valcorp Fine Foods which is headed by John Valmorbida. Valcorp is the local distributor for brand names including Lavazza coffee, La Zuppa soup, La Gina tomatoes, Sirena tuna and Evian water.
Histamine Toxicity (Scombroid Fish Poisoning)
Scombroid fish poisoning, also known as histamine toxicity, occurs when bacteria in improperly stored tuna produce large amounts of histamines. Even people without a tuna allergy can experience symptoms similar to an allergic reaction if they eat contaminated fish.
The unhealthiest fish to eat are typically large, predatory species high in mercury like shark, swordfish, king mackerel, and imported tilefish, plus bluefin tuna, which are dangerous for brain/nerve health, especially for pregnant women and children; also, farmed salmon and some imported tilapia/catfish raise concerns for contaminants and antibiotics, while orange roughy and Atlantic cod are often cited for high mercury and overfishing/sustainability issues.
This explanation is further corroborated by the fact that fish is a source of tryptophan, the precursor for serotonin. Thus, the present results are consistent with work by Hartmann, who found that tryptophan increased sleepiness.
