Reading Seafood Labels
Every field on a seafood label tells you something — or reveals what is being hidden. Here is how to read them.
Field by Field
Some fields are required by law, others are voluntary signals of transparency. Both matter.
What it means
The common name and, for retail, the market name accepted by the FDA.
Why it matters
"Rock salmon" and "dogfish" are the same animal. Market names can obscure species identity.
What to do
Look for the scientific name on premium products — it's harder to fake.
What it means
Where the fish was harvested. Required by federal law at retail (Country of Origin Labeling, or COOL).
Why it matters
Most of the world's "fresh Atlantic salmon" is farmed in Norway or Chile. COOL tells you where, not how.
What to do
"Product of USA" plus a named state (Alaska, Maine, Gulf of Mexico) is the most specific and reliable form.
What it means
Required disclosure at retail in the U.S. since 2005.
Why it matters
The label is binary and tells you nothing about harvest method, feed inputs, or management quality.
What to do
A farm-raised fish from a well-managed operation is often preferable to wild-caught from an unmanaged fishery.
What it means
How the fish was caught: hook-and-line, troll, seine, gillnet, longline, pot, trawl.
Why it matters
This is the single most useful piece of information for environmental impact and quality. It is also voluntary.
What to do
If it is not on the label, ask. If the seller does not know, that is information too.
What it means
A "sell by" or "use by" date on fresh fish. Not federally required but common.
Why it matters
Freshness is degraded from the moment of catch. A date without a harvest date tells you half the story.
What to do
The most honest sellers list harvest date, not just sell-by date. Two-week-old "fresh" fish is not the same as two-day-old fresh fish.
What it means
Logos like MSC, ASC, BAP, or Best Choice. Each has different audit standards and coverage.
Why it matters
Certification is a proxy for managed, documented harvest — but audit quality varies significantly.
What to do
MSC is generally the strongest for wild-caught. ASC is the equivalent for farmed. Neither guarantees flavor or handling quality.
What it means
An alphanumeric code or QR code linking the product back to a specific harvest event.
Why it matters
This is what makes a product actually traceable — not just labeled, but verifiably connected to its origin.
What to do
If a QR code is present, scan it. A code that leads to real harvest data is a strong signal of transparency.
Red Flags
Labels tell you what sellers want you to know. These patterns reveal what they may not want you to ask.
No country of origin
Required by law at retail. Missing at a fish counter is a regulatory violation.
"Pacific" or "Atlantic" without a country
Ocean names are not origin claims. This is technically legal but often misleading.
Species mismatch
"Grouper," "red snapper," and "sea bass" are frequently substituted with cheaper species. FDA seafood fraud studies find 20%+ substitution rates at retail.
"Previously frozen" in small print
Required disclosure. A fish sold as fresh that was previously frozen is not illegal, but it should be priced and treated differently.
Vague method claims
"Sustainably harvested" without a certification or method name is marketing copy, not a verifiable claim.
The Hierarchy of Trust
A label with species name, named state of origin, harvest method, and a lot code you can trace beats any certification. Certifications are a proxy; traceability is the real thing. When you can buy direct from a named fisherman, you have bypassed the label problem entirely.
