Mercury accumulation in tuna is not a myth — it is a measurable health risk that shifts with every species you choose. The difference between albacore and skipjack is not marketing; it is an average of 50% less mercury per can, according to Consumer Reports testing. That is the single most important spec when buying tuna for weekly lunches, pregnancy-safe meals, or daily protein intake.
I’m Emma — the founder and writer behind Baby Bangs. I spend my time digging through nutritional data, third-party heavy metal testing reports, and FDA mercury level charts so you do not have to guess which can is safe for your family.
This guide breaks down the five most reliable options for low-mercury tuna — sorted by species, sodium content, and convenience — so you can stock your pantry with confidence.
How To Choose The Best Low-Mercury Tuna
Not all tuna is created equal when it comes to mercury content. The species, size, and age of the fish directly determine how much methylmercury ends up in your can. Here is what to look for to keep your exposure low without sacrificing taste or convenience.
Species First: Skipjack vs. Albacore
Skipjack is the smallest and most abundant species used in canned tuna, which means it accumulates far less mercury over its shorter lifespan. Consumer Reports found that skipjack averages 0.126 ppm of mercury, while albacore averages 0.350 ppm — nearly triple. If low mercury is your priority, skipjack is the only species to buy.
Sodium and Packing Liquid
Tuna packed in water has significantly less sodium than oil-packed versions, and skipping added salt further reduces sodium intake. Look for “no salt added” labels if you are watching blood pressure or feeding young children. Pouches also contain less liquid than cans, making them easier to drain and mix.

In‑Depth Reviews
1. Chicken of the Sea Wild Caught Light Tuna in Spring Water Pouches
This pack of 12 pouches delivers 100% skipjack tuna — the species with the lowest mercury levels in the canned fish aisle. Each 2.5-ounce pouch packs 11 grams of lean protein and is packed in spring water with no draining required. The Marine Stewardship Council certification on every pouch confirms sustainable fishing practices, so you are supporting healthy oceans while protecting your family from heavy metal exposure.
Skipjack is naturally lower in mercury than albacore, and this brand’s commitment to MSC certification means every skipjack is wild caught and traceable. Customers consistently praise the pouches for their convenience: tear open, mix with crackers or a salad, and eat without the mess of a can. The mild, not-too-fishy flavor works perfectly for keto, paleo, and Mediterranean meal plans.
One thing to note: the pouch size is smaller than a standard 5-ounce can, so you may need two pouches for a full sandwich. But for a single-serving lunch or a quick protein hit, the pouch format is a game-changer for busy schedules.
Why it’s great
- 100% skipjack species tested for half the mercury of albacore
- MSC-certified sustainable and dolphin safe
- No draining required — tear-and-eat convenience
Good to know
- 2.5 oz pouches are smaller than standard cans
- Some find the flavor slightly fishy compared to albacore
2. 365 by Whole Foods Market Skipjack Tuna in Water No Salt Added
If you are looking for tuna with the least mercury and zero added sodium, this 6-pack of skipjack cans hits both requirements perfectly. The 5-ounce cans contain skipjack packed in water with no salt added, making this one of the cleanest options available. Consumer Reports specifically highlighted skipjack brands for averaging half the mercury content of albacore, and this 365 product delivers on that promise.
UPC code 099482528058 confirms this is a Whole Foods standard — they skip the gimmicks and focus on ingredient simplicity. Customers report using it for everything from tuna salad to pasta tosses, with particular praise from those on low-sodium diets or feeding tuna to their dogs. The dolphin-safe certification adds peace of mind.
The only catch (pun intended) is that the can must be drained, unlike the pouch formats. But if you value zero sodium and the lowest mercury species available, this is a pantry staple worth stocking up on.
Why it’s great
- Skipjack species with mercury levels half that of albacore
- Zero added salt — ideal for sodium-restricted diets
- Trusted by Whole Foods with dolphin-safe certification
Good to know
- Requires can opener and draining
- Mild flavor may be too subtle for some
3. StarKist Light Tuna in Water Pouch 12-Pack
StarKist’s Light Tuna pouches deliver 17 grams of protein per serving with only 70 calories, making them a high-density protein source for anyone tracking macros. Each 2.6-ounce pouch is packed with chunk light tuna — which is skipjack — so you get the same low-mercury species as the more premium brands at a budget-friendly price. The pouches require no draining and are gluten-free, soy-free, and dolphin safe.
Customers consistently rate this product 5 stars for its fresh, mild taste and lack of fishy aftertaste. The tear-and-eat design makes it ideal for throwing into a gym bag, lunchbox, or carry-on. Reviewers specifically note that it works well in tortilla wraps, over crackers, or straight from the pouch when hunger strikes.
It is worth noting that some sodium is present (around 250mg per pouch), so if salt is a concern, the no-salt-added option from Whole Foods may be a better fit. But for a portable, low-mercury protein source that tastes great, this pouch is a winner.
Why it’s great
- Skipjack species ensures low mercury exposure
- 17g protein per pouch with only 70 calories
- No draining needed — truly grab-and-go
Good to know
- Contains added salt (not no-salt-added)
- Pouch size is smaller than standard 5 oz cans
4. Bumble Bee Chunk Light Tuna in Water 24-Pack
Bumble Bee’s chunk light tuna is skipjack, giving it the same low-mercury advantage as the other skipjack options in this guide. Each 5-ounce can delivers 23 grams of protein and 220mg of DHA and EPA omega-3s, making it one of the most nutrient-dense choices per dollar. The 24-pack case is ideal for serious meal preppers who want to stock their pantry with a reliable, sustainable protein source.
The cans are MSC Certified Sustainable and dolphin safe, with a Trace My Catch code on each can that lets you see exactly where your tuna was caught. Customers rave about the value — at this bulk volume, the cost per can is impressively low. Reviewers also note the clean, flaky texture and balanced flavor that works equally well in casseroles, salads, and sandwiches.
The only practical limitation is that these are standard cans requiring draining, so they are not as portable as pouches. But for home cooking and bulk storage, this is the best value in the low-mercury tuna space.
Why it’s great
- Skipjack species with half the mercury of albacore
- 23g protein and 220mg omega-3s per can
- MSC certified with traceability codes
Good to know
- Standard cans require draining and a can opener
- Not ideal for single-serve on-the-go use
5. StarKist 25% Less Sodium Chunk Light Tuna in Water 24-Pack
This StarKist option takes the standard chunk light tuna and cuts the sodium by 25%, bringing each serving to 270mg of sodium — a meaningful reduction for anyone on a DASH diet or watching their blood pressure. The tuna is still skipjack, so the mercury levels remain low, and each 5-ounce can packs 20 grams of protein with only 90 calories.
Customers who buy this bulk pack appreciate the balance between low mercury and lower sodium, as many low-mercury options skip the sodium reduction. The cans are wild caught, dolphin safe, and work well with keto, paleo, Mediterranean, and Weight Watchers plans. Reviewers consistently mention that the flavor holds up well in cold tuna salad and hot casseroles alike.
The 24-pack is heavy on storage space, so be sure you have pantry room. Also, the 25% less sodium still contains more salt than a no-salt-added product, so if you need zero sodium, stick with the Whole Foods option above. But if you want a bulk skipjack supply with less salt than standard tuna, this is your best bet.
Why it’s great
- Skipjack species with 25% less sodium than standard light tuna
- 20g protein per can for under 100 calories
- Wild caught, dolphin safe, and diet-friendly
Good to know
- Still contains 270mg sodium per serving
- Bulk case requires significant pantry space
