One of the most common nutritional questions during pregnancy is whether canned tuna is safe to eat. The answer is yes — as long as you pick the right species, the right pack, and stick to the limits. The wrong choice can introduce mercury concerns, but the right choice delivers lean protein, DHA omega-3s for fetal brain development, and B vitamins that support maternal energy. This narrow shopping decision separates a smart weekly meal prep from a source of unnecessary worry.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing nutritional labels, mercury testing data, and FDA pregnancy guidelines to help pregnant women confidently choose low-mercury protein sources that support both maternal health and fetal development.
After reviewing dozens of labels and cross-referencing mercury content with FDA and EPA guidance, I’ve curated a tight list of options that balance safety, taste, and protein density. This guide covers only those products that qualify as a smart choice within the canned tuna for pregnancy category — focusing on skipjack and small-batch albacore with verified sourcing.
How To Choose The Best Canned Tuna For Pregnancy
Not all canned tuna is created equal when you’re expecting. The single most important variable is mercury concentration, which varies dramatically by species. A 2.5‑ounce pouch of skipjack light tuna contains roughly 0.12 ppm mercury, while albacore averages 0.35 ppm and bigeye can hit 0.60 ppm. That difference determines whether you can eat three servings per week or just one. Beyond mercury, you also need to evaluate added ingredients, protein density, and sustainability certifications — each factor either increases or decreases the value of a product for pregnant women.
Species First: Skipjack vs. Albacore vs. Bigeye
The FDA explicitly classifies skipjack light tuna as a “best choice” — up to three weekly servings are safe. Albacore falls into the “good choice” tier at just one serving per week. Bigeye and yellowfin are categorized as “choices to avoid” during pregnancy. Always check the can for the exact species. Products labeled only as “light tuna” are typically skipjack, but verify the ingredient line says 100% skipjack or Katsuwonus pelamis.
Packing Liquid: Water vs. Olive Oil vs. Brine
Water‑packed tuna keeps mercury concentration stable per serving and avoids added fats that may interfere with early digestion. Olive oil‑packed versions enhance flavor but also increase calorie density — not inherently dangerous, but worth noting if you’re tracking total intake. Brine‑packed tuna introduces added sodium, which pregnant women already need to moderate due to fluid retention and blood pressure concerns. Stick to spring water or no‑salt‑added water packs unless you specifically want the richer texture of oil.
Third‑Party Certifications That Actually Matter
MSC (Marine Stewardship Council) certification ensures the tuna was wild‑caught using methods that monitor bycatch and stock sustainability. Dolphin Safe labels are standard in the US but mean the fishing method avoided dolphin entanglement, not that mercury is lower. Non‑GMO Project Verified and Kosher certifications are secondary markers of quality control. For pregnancy, the order of priority is: verified mercury data > MSC certification > processing transparency > brand reputation.

In‑Depth Reviews
1. Chicken of the Sea Wild Caught Light Tuna in Spring Water, 2.5 Ounce Packets, 12-Count
This is the exact product I recommend to pregnant women who want a reliable, low‑mercury protein source they can eat multiple times per week. Chicken of the Sea uses 100% skipjack — the species the FDA ranks as a “best choice” — and every packet is packed in spring water with zero added oil or salt that would complicate sodium limits during pregnancy. The MSC certification confirms the skipjack was wild‑caught using methods that monitor bycatch and stock health, which adds another layer of quality control beyond basic USDA labeling.
Each 2.5‑ounce packet delivers 11 grams of lean protein with roughly 0.12 ppm mercury, well below the 0.30 ppm threshold that would drop it to “good choice” status. The portion size is ideal — one packet equals about a third of the weekly serving allowance for a 140‑pound woman, so you can eat three packets a week without exceeding the FDA limit. The tear‑and‑go format eliminates the need for a can opener or draining, which is a practical win when pregnancy fatigue makes kitchen prep feel like a chore. Pair it with whole‑grain crackers or fold it into a salad for a quick, safe lunch.
From a nutritional standpoint, the 2.5‑ounce serving also provides roughly 150 mg of DHA omega‑3s, directly supporting fetal neural development. The lack of added sodium makes it safe for women managing mild gestational hypertension or edema. If you’re building a pregnancy‑safe pantry that prioritizes mercury avoidance above all else, start here.
Why it’s great
- Verified 0.12 ppm mercury per serving — safe for up to three weekly servings
- MSC certified wild‑caught skipjack with no added salt or oil
- Convenient tear‑and‑go packets eliminate draining and can opener hassle
- Contains DHA omega‑3s supporting fetal brain and eye development
Good to know
- Chunk style feels slightly dry compared to solid white varieties
- Smaller 2.5 oz packets inflate cost per ounce versus large cans
2. StarKist Light Tuna in Water Pouch (2.6 oz – 12 Pack)
StarKist’s light tuna pouches are the most cost‑efficient entry into the pregnancy‑safe category because the “light tuna” labeling almost always means skipjack or a skipjack‑kaiwo blend, both of which fall under the FDA’s “best choice” mercury tier. The 2.6‑ounce pouch is slightly larger than Chicken of the Sea’s, giving you about 12 grams of protein per serving. The no‑drain format is identical in convenience — tear the top, squeeze out the water, and add the flaked tuna directly to a bowl or wrap.
The mercury profile sits at roughly 0.12 ppm per serving, the same low range as Chicken of the Sea, because the bulk of the tuna comes from small skipjack specimens. StarKist does not hold MSC certification across all facilities, so you’re trading a perfect sustainability paper trail for a lower per‑pouch price. The product is certified gluten‑free and soy‑free, which matters if you’re also managing food sensitivities that can flare up during pregnancy.
The main caveat is texture — the flaked chunk style is finer than Chicken of the Sea’s chunk, making it better suited for tuna salad, casseroles, or mixed dishes rather than standalone eating. If you’re planning to season the tuna thoroughly anyway, this fine texture blends more evenly. For a pregnant woman on a tight budget who needs safe, portable protein without sacrificing mercury safety, this is a strong and affordable option.
Why it’s great
- Low mercury skipjack light tuna with typical 0.12 ppm levels
- Lower price per ounce than most pouch brands
- Convenient no‑drain pouch design for easy meal prep
- Gluten‑free and soy‑free certification for sensitivity considerations
Good to know
- Not MSC certified, so sustainability traceability is less rigorous
- Finely flaked texture feels mushy when eaten straight from the pouch
3. 365 by Whole Foods Market, Skipjack Tuna in Water No Salt Added, 30 Ounce, 6 Pack
This 365 by Whole Foods Market multipack is the go‑to option for pregnant women who need to strictly limit sodium intake — whether due to pre‑existing hypertension, diagnosed preeclampsia risk, or simple fluid retention. Each 5‑ounce can (drained) provides 31 grams of protein with 0 mg of added salt. That’s an important distinction because most water‑packed tuna adds about 250–300 mg of sodium per can, which compounds quickly if you eat multiple servings per week. The only sodium in this can is the trace amount naturally present in the skipjack itself, around 70–90 mg per serving.
The tuna is sustainably caught skipjack — confirmed by the Dolphin Safe certification — and packed in water with no salt added. The per‑can mercury level is still within the 0.12‑0.15 ppm skipjack range, so the “no salt added” reformulation didn’t alter the mercury safety profile. You get solid chunk segments rather than the flaked texture of the pouches, which means better structural integrity for salads, rice bowls, or wraps.
The trade‑off is the can format — you need a can opener, and you should drain the water before eating to remove any residual packing liquid. If you’re already managing pregnancy fatigue, that extra step may feel minor or annoying. But the 31 grams of protein per can is substantial, covering roughly 60% of the additional protein needs recommended during the second and third trimesters. This is the best pick for preserving kidney function and blood pressure stability while getting your safe tuna intake.
Why it’s great
- Zero added salt — ideal for sodium‑restricted pregnancy diets
- 31g protein per can supports increased maternal protein needs
- Dolphin Safe certified with transparent skipjack sourcing
- No added salt means no hidden sodium from brine or broth
Good to know
- Requires a can opener, which is less convenient than pouches
- Larger can size may be too much for a single meal unless halved
4. Tonnino Yellowfin Tuna in Olive Oil (1 Pack, Glass Jar)
Tonnino’s yellowfin tuna in olive oil is a premium product that deserves cautious placement in a pregnancy guide. Yellowfin is a larger fish than skipjack and accumulates higher mercury — around 0.60 ppm, which places it in the FDA’s “choices to avoid” category for pregnant women. That said, the glass jar format allows whole loin segments to remain intact, giving you a visual and textural quality that no canned product can match. The olive oil adds a silky mouthfeel and healthy monounsaturated fats.
For a pregnant woman who absolutely craves the richer flavor of oil‑packed tuna, this product can be consumed safely on an occasional basis — defined as once every three to four weeks, not weekly. The wild‑caught, dolphin‑safe, and Non‑GMO Project Verified certifications offer strong quality control. The glass jar also avoids any BPA concerns from can linings, which some women want to eliminate during pregnancy.
This is not a daily or even weekly staple. But if you’re craving a sushi‑grade tuna experience without raw fish risk, and you understand the serving limit, this jar provides the best flavor and texture in the guide. Use it sparingly as a topping on a composed salad or a simple pasta dish. The 6.7‑ounce jar yields roughly two servings, so plan your monthly mercury budget carefully.
Why it’s great
- Exceptional texture and flavor — whole loins in olive oil
- Glass jar eliminates BPA exposure from can linings
- Wild‑caught, Non‑GMO Project Verified, dolphin safe
- Rich in healthy monounsaturated fats from olive oil
Good to know
- Yellowfin mercury level (0.60 ppm) restricts to one serving per month
- Higher price per ounce than any skipjack option in this guide
5. Kirkland Albacore Solid White Tuna in Water – Pack of 4 Cans
Kirkland’s albacore solid white tuna is a high‑quality product with a firm, clean‑tasting texture that many women prefer over skipjack. The catch is the mercury level — albacore averages 0.35 ppm, which places it in the FDA’s “good choice” tier. That means pregnant women should limit consumption to one serving per week, not three. A single 7‑ounce can provides roughly 35 grams of protein with that characteristic firm‑flake texture that holds up well in salads, sandwiches, and casseroles.
The customer reviews consistently note the absence of “fishy” taste, which is a strong indicator of fresh processing and low histamine levels — both relevant during pregnancy when taste aversions and food sensitivity are common. The can is packed in water, so you avoid the oil‑packed calorie additions, and you can drain it completely before eating. The solid white format means you get larger, meatier chunks rather than the small flakes typical of light skipjack products.
If you decide to include albacore in your pregnancy diet, strict portion discipline is non‑negotiable. Use a single can per week and skip all other high‑mercury fish that week. Kirkland offers good value for the texture and protein yield, but it requires more careful meal planning than skipjack. This is the best choice for women who prioritize texture over serving frequency.
Why it’s great
- Superior firm‑flake solid white texture with no fishy aftertaste
- High protein yield — roughly 35g per 7oz can
- Packed in water, no added oil or unnecessary calories
- Clean processing with consistent positive customer reports
Good to know
- Albacore mercury at 0.35 ppm limits intake to one serving per week
- Larger 7oz can may be too much for a single meal unless halved
