Sainsbury's Boneless Mackerel Fillets in Spring Water

Sainsbury's Boneless Mackerel Fillets in Spring Water are a part of the retailer's core seafood range, emphasizing sustainability and nutritional value. The mackerel (Scomber scombrus) is wild-caught in the North East Atlantic, specifically the Northern North Sea, using trawl methods.

Tracing the production through the packaging's health mark (GB BB 008), the product is processed and canned at the International Fish Canners facility in Fraserburgh, Scotland. This facility is a major supplier for UK supermarkets, ensuring that the fish is tinned close to the source to maintain quality.

The brand belongs to J Sainsbury plc, a British retail institution founded in 1869. While it remains a public company listed on the London Stock Exchange, its ownership is diversified among global institutional investors and sovereign wealth funds, reflecting its evolution from a family-run dairy shop to a major 21st-century global enterprise.
