Last updated: April 2026 dataFrozen whole mackerel — principally Atlantic mackerel (Scomber scombrus) and chub mackerel (Scomber japonicus) — is a high-volume commodity in global seafood trade, widely used for direct consumption, smoking, canning, and as fishmeal feedstock. Norway and Iceland together dominate the Northeast Atlantic harvest and lead US import supply, with Vietnam and South Korea also significant sources reflecting Pacific and re-export trade flows. Mackerel's high oil content makes cold-chain integrity critical; temperature abuse during transit can accelerate histamine formation, a food safety concern that FDA monitors at entry. Importers should ensure foreign processors maintain HACCP controls specifically addressing histamine in scombroid fish.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Mackerel is a scombroid fish with naturally high levels of free histidine, which bacteria convert to histamine if the fish is temperature-abused at any point in the cold chain. FDA sets action levels for histamine in fish and may detain or refuse shipments where testing reveals elevated levels. Importers should require time-temperature records from foreign processors and verify that HACCP plans specifically address scombrotoxin formation.
Atlantic mackerel is managed under Northeast Atlantic fisheries agreements, and annual quota disputes between Norway, Iceland, the EU, and the Faroe Islands can affect total allowable catch and export volumes. When negotiations break down or quotas are cut, export availability from these leading suppliers can tighten, potentially shifting US buyers toward Pacific sources such as Vietnam or South Korea.
