The mercury content in tuna isn’t a one-size-fits-all number; it changes dramatically depending on the species, size, and origin of the fish. Most shoppers grab the cheapest can without checking the label, unknowingly choosing larger, older fish like Albacore or Yellowfin that accumulate significantly higher mercury levels over their longer lifespans. This guide eliminates the guesswork by focusing on the specific species and sourcing practices that produce the safest, lowest-mercury options available on Amazon.
I’m Mohammad — the founder and writer behind ProteinJug. I spend my time cross-referencing seafood mercury databases, analyzing species-specific contamination patterns, and comparing the sourcing claims of every canned and pouched tuna brand to ensure you’re getting genuine low-mercury choices, not just marketing labels.
Each product reviewed here is selected because it uses smaller, short-lived fish like Skipjack, or it provides transparent, traceable sourcing that aligns with low mercury guidelines. Whatever your meal prep or snacking routine, this research-backed guide will help you confidently select a low mercury tuna that protects your health without compromising on flavor or convenience.
How To Choose The Best Low Mercury Tuna
Selecting a low mercury tuna isn’t about brand prestige; it’s entirely about the species and the age of the fish at harvest. Larger, predatory fish at the top of the food chain accumulate the highest mercury concentrations, so your first filter should always be the species on the label. Once you’ve identified a safe species, consider the packing liquid, added sodium, and the convenience of the packaging format to match your cooking habits.
Prioritize Skipjack for the Lowest Mercury Baseline
Skipjack tuna is the smallest and fastest-reproducing of the commercial tuna species, meaning it spends the least amount of time accumulating mercury from its prey. According to FDA and EPA seafood guidance, Skipjack (labeled “Chunk Light”) is consistently grouped among the lowest-mercury commercial tuna choices, while Albacore (“Solid White”) carries meaningfully higher mercury levels. If your main priority is minimizing mercury, “Chunk Light” tuna is almost always made from Skipjack, making it the safest default choice. For exact numbers, always check the current FDA/EPA “Advice about Eating Fish” reference rather than relying on any single figure, since lab results vary by catch and testing batch.
Distinguish Between “Light” and “White/Albacore” Labels
A “Chunk Light” label almost universally indicates Skipjack tuna. In contrast, “Solid White” or “Albacore” tuna comes from a larger, longer-lived fish with significantly higher mercury levels. Some “Light” tunas may also include Yellowfin, which is a larger species than Skipjack and carries intermediate mercury values. For daily or near-daily consumption, you want a product that explicitly states “Skipjack” or uses the “Chunk Light” designation from a trusted brand that doesn’t mix species.
Evaluate Packing Liquid and Added Ingredients
Tuna packed in water is the leanest option and allows you to control your own seasoning and fats. Tuna packed in olive oil, particularly premium Yellowfin, offers a richer flavor and texture, but the oil itself can be high in calories. For low-mercury tuna, always verify the species first — if a “Tuna in Olive Oil” product uses Yellowfin, the mercury advantage disappears. Additionally, check for “No Salt Added” versions to keep your overall sodium intake in check, especially if you use tuna frequently in salads or as a main protein.

In‑Depth Reviews
1. 365 by Whole Foods Market Skipjack Tuna No Salt Added (6-Pack)
The 365 Whole Foods Skipjack hits the sweet spot for anyone serious about low mercury intake. Each can delivers wild-caught Skipjack, rich in lean protein, and is among the lowest-mercury commercial tuna species per FDA/EPA guidance. The “No Salt Added” formulation is a critical advantage for daily consumption, allowing you to season precisely without ingesting hidden sodium that often plagues standard canned tuna.
This is a Dolphin Safe certified, sustainably caught Skipjack option positioned as an everyday, low-sodium pantry staple. The pieces are smaller than solid Albacore, but for salads, sandwiches, and casseroles, the flaky texture works perfectly.
The only practical trade-off is that the tuna pieces are “skipjack chunk” rather than the large solid fillets some people expect from premium cans. However, for a product that costs about the same as standard tuna while offering verified low-mercury and low-sodium credentials, this is the daily-driver choice for health-conscious households.
Why it’s great
- Skipjack species with lowest mercury profile in commercial tuna
- No salt added allows full control over sodium intake
- Excellent value for a 6-pack of large 5-oz cans
Good to know
- Fish pieces are smaller chunks, not solid fillets
- Mild flavor may be less distinctive than oil-packed varieties
2. Genova Premium Yellowfin Tuna in Olive Oil (12-Pack)
Genova has built its reputation around using premium Yellowfin tuna, hand-filleted and packed in rich olive oil. While Yellowfin is a larger species with intermediate mercury levels (lower than Albacore but higher than Skipjack), Genova’s sourcing and processing excellence make this the gold standard for occasional indulgence when you want the texture and flavor of a solid fillet. Each 5-ounce can delivers 29 grams of lean protein and heart-healthy omega-3s from wild-caught fish.
Genova markets this as hand-filleted, wild-caught Yellowfin packed in rich olive oil, with a resealable lid designed for easier repeat use. The brand positions it around solid, meaty texture rather than flaked chunks, which fits salads, pasta, and appetizers where a premium fillet is the point.
This 12-pack commands a premium cost compared to standard Skipjack options. For daily consumption, you would want to rotate this with lower-mercury species. However, for a special salad, pasta dish, or appetizer where the quality of the fish and oil matters, Genova delivers a noticeably superior product that justifies the price.
Why it’s great
- Premium hand-filleted Yellowfin with meaty, solid texture
- Packed in rich olive oil that enhances Mediterranean dishes
- Non-GMO, wild caught, and Kosher certified
Good to know
- Yellowfin contains moderate mercury; not for single-species daily use
- Premium price point puts it beyond everyday pantry staple budgets
3. Freshé Gourmet Skipjack Tuna Variety Pack (4-Pack)
Freshé redefines low-mercury tuna by turning it into a ready-to-eat meal rather than a simple protein ingredient. Each 4.25-ounce BPA-free tin contains certified sustainably caught wild Skipjack tuna (Friend of the Sea) blended with fresh vegetables, herbs, and spices in one of four globally inspired flavors: Aztec Ensalada, Provence Nicoise, Thai Sriracha, and Sicilian Caponata. This eliminates the need for any assembly at lunchtime.
Freshé markets these as ready-to-eat tins blending Skipjack tuna with fresh vegetables, herbs, and spices across the four flavor varieties. The 4-year shelf life makes these excellent for pantry stocking and emergency meal planning.
The primary drawback is the price: this four-pack costs significantly more than buying bulk Skipjack cans and adding your own vegetables. Some buyers found the non-green-can flavors less appealing. But for those who value convenience and want a guaranteed low-mercury meal that’s ready to eat straight from the tin, Freshé delivers a unique combination of safety and gourmet taste that no other product in this category matches.
Why it’s great
- Complete meal ready-to-eat with Skipjack tuna and vegetables
- BPA-free tins and Friend of the Sea sustainability certification
- Four distinct global flavors prevent taste fatigue
Good to know
- Premium pricing for the four-pack limits everyday affordability
- Not all flavors appeal equally; best to try variety pack first
4. StarKist Light Tuna in Water Pouch (2.6 oz – 12 Pack)
StarKist Light Tuna in Water is the classic low-mercury option for anyone seeking maximum convenience at a very accessible price. The “Chunk Light” designation means this is almost exclusively Skipjack tuna, which keeps mercury levels low. Each 2.6-ounce tear-and-eat pouch provides 17 grams of protein and 70 calories with a clean, mild taste that customers describe as “fresh” and “not too salty.”
The pouch format is the standout feature here: no draining required, no can opener needed, and it’s lightweight enough for backpacks, lunchboxes, or desk drawers. StarKist markets this as a mild-flavor, wild caught, dolphin-safe pouch built for quick snacks and meals on the go. The 12-pack allows you to stock up for quick salads or sandwiches without worrying about spoilage.
The pouch size is smaller than a standard 5-ounce can, and the 12-pack cost is slightly higher per ounce than bulk canned Skipjack options. The texture can sometimes vary — some pouches arrive packed very firm while others have more water — but the flavor remains consistent. For a portable, no-mess, reliably low-mercury tuna, this is one of the most practical options available.
Why it’s great
- No draining or can opener needed; tear-and-eat convenience
- Chunk Light (Skipjack) ensures low mercury levels
- Light 2.6-oz pouches are ideal for on-the-go meals
Good to know
- Smaller serving size than standard cans
- Slightly higher cost per ounce than canned Skipjack
5. Ortiz Yellowfin Tuna in Olive Oil (Jar)
Ortiz Yellowfin Tuna in Olive Oil represents the artisanal end of the tuna spectrum, and it’s priced accordingly. The 220-gram jar holds whole Yellowfin (Ahi-grade) loin, cooked and preserved in olive oil rather than mashed into chunks like grocery-store cans. The glass packaging lets you see the quality of the fillet before opening, which is a visual assurance you don’t get with cans or pouches.
Ortiz positions this as a step above everyday canned tuna — a loin-style fillet meant to be served straight from the jar with bread, crackers, or a salad, rather than mixed into a sandwich.
The single 220-gram jar has a premium cost, and the Yellowfin species places it in the moderate mercury category rather than the lowest tier. This is not a product for daily meal prep; it’s a specialty item for when you want to impress yourself or guests with a genuinely different tuna experience. For those who prioritize flavor and texture above all else, the Ortiz jar is a strong pick, but your mercury-conscious routine should still favor Skipjack for frequent consumption.
Why it’s great
- Whole Yellowfin loin provides a different texture and presentation than canned chunk tuna
- Glass jar shows the product quality before purchase
- Preserved in olive oil, no mashing
Good to know
- Yellowfin has moderate mercury; not suitable for daily consumption
- Premium pricing limits it to occasional gourmet use
