10 Grocery Store Fish You Should Never Buy (According to Fishmongers)

So you’re at the grocery store, staring blankly at the seafood counter. It all looks so fresh, so appealing… but hold on! Not all fish are created equal.

Experienced fishmongers know which to avoid, and we’re letting you in on their secrets. This list reveals ten fishy friends you might want to steer clear of, for your health and the health of our oceans.

From mercury worries to unsustainable practices, we’re breaking down why these ten should be left on the shelf. Get ready to become a seafood savvy shopper!

Swordfish

Swordfish is delicious, but its high mercury content makes it a risky choice, especially for pregnant women and young children. The FDA advises limiting your consumption to minimize potential health problems. This one’s best avoided unless you’re a very occasional consumer.

Shark

Similar to swordfish, shark boasts impressive mercury levels. Plus, many shark fishing practices damage marine ecosystems. For both your health and the planet’s, there are much better seafood choices available.

Tilefish

Tilefish is another high-mercury offender. The FDA recommends avoiding it altogether, especially for pregnant women, young children, and anyone concerned about mercury exposure.

King Mackerel

This tasty fish also contains significant amounts of mercury, making it a no-go for pregnant women and children. Better to choose a lower-mercury alternative.

Bigeye Tuna

Often a sushi favorite, bigeye tuna packs a powerful mercury punch. While delicious, regular consumption can lead to mercury buildup. Moderation is key, but there are healthier options.

Albacore Tuna (canned)

Canned albacore tuna often has higher mercury levels than light tuna. While convenient, limiting your intake is a smart move for your health.

Farmed Salmon

While salmon is a nutritional powerhouse, farmed salmon often contains higher levels of contaminants and PCBs than wild-caught varieties. Always choose wild-caught if possible.

Chilean Sea Bass

Often mislabeled and overfished, Chilean sea bass (actually Antarctic toothfish) is a questionable choice both ecologically and in terms of potential contamination. Look for more sustainable options.

Pacific Cod (from certain sources)

Pacific cod itself is a healthy fish, but some sources engage in practices that affect quality. Look for sustainably sourced Pacific cod to be sure you’re making a healthy choice.

Farmed Shrimp

Farmed shrimp are often raised in environments that expose them to antibiotics and other potentially harmful substances. Plus, their farming often contributes to environmental problems. Consider wild-caught shrimp or another seafood option instead.
