The Simple Ingredients Revealed
For John West's canned tuna in spring water, simplicity is key. A look at the product label reveals an incredibly straightforward list, typically comprising just three core components:
- Tuna (Fish): The primary ingredient is high-quality tuna, often identified as Skipjack tuna (Katsuwonus pelamis) on some product labels. This species is favored for its taste and suitability for canning.
- Spring Water: Rather than oil or a heavily salted brine, pure spring water is used as the canning liquid. This keeps the fat and sodium content lower, allowing the natural flavor of the fish to shine through.
- Salt: A small amount of salt is added to enhance the flavor and aid in the preservation process. The overall sodium level, however, is typically much lower than in tuna packed in brine.

The Meticulous Canning Process
John West follows a rigorous process to ensure the quality and safety of its canned tuna:
- Sourcing: Tuna, such as Skipjack, is sourced from sustainable fisheries, often from the Western Pacific Ocean, and handled with care to maintain freshness.
- Preparation: At the cannery, the fish is cleaned, deboned, and filleted by hand.
- First Cooking: The loins are cooked to perfection in large steam ovens to remove excess moisture and enhance flavor.
- Packing: The cooked tuna is then packed into cans, along with the spring water and a touch of salt.
- Second Cooking (Retort): The sealed cans undergo a second, high-temperature cooking process (retorting) in specially constructed pressure cookers. This sterilizes the product and ensures a long, safe shelf life.
Sustainability and Safety Practices
As a responsible brand, John West prioritizes both environmental sustainability and consumer safety:
- Sustainable Sourcing: A significant portion of John West's seafood is certified sustainable by the Marine Stewardship Council (MSC). This ensures that fishing practices are responsible and that fish stocks remain healthy.
- Traceability: John West offers a feature allowing customers to trace their tuna back to its origin by entering a can code, promoting transparency.
- Mercury Monitoring: John West conducts routine testing for mercury levels to ensure they remain within strict regulatory limits. However, health authorities like the UK Food Standards Agency recommend that pregnant women or those trying to conceive limit their intake to four medium cans per week due to mercury accumulation.
