Responsible Sourcing Supply Chain

Supply Chain

We always abide by the United Nations Convention on the Law of the Sea (UNCLOS). This means we won’t source from areas of the ocean which are protected, such as areas for breeding fish, or no-take zones where fish stocks and the ecosystems are safeguarded.

Francisco Leotte, our Fisheries Sustainability Manager.

Whenever we look into using fish from a new source/fishery, or develop new products, we conduct all the appropriate risk assessments to ensure the raw material fully complies with our fish sourcing policy.

In order to analyse and monitor the status of fisheries relevant to our business, we employ an in-house Fisheries Sustainability Manager. He is also responsible for conducting fishery risk assessments, actively collaborating in Fishery Improvement Projects (FIPs) and, most importantly, engaging with stakeholders to ensure good industry practices are fully implemented across all relevant partners.


Each of the overseas Thai Union tuna plants in Ghana and Seychelles, supplying John West, is Marine Stewardship Council (MSC) Chain of Custody certified. This certification guarantees the efficiency of our traceability system. At no stage of the canning process will MSC certified fish get mixed with non-certified fish.

In addition, all plants supplying John West are British Retail Consortium (BRC) certified. BRC is a standard aimed at defining common food safety requirements for food producers, including some of the strictest traceability requirements.

International Seafood Sustainability Foundation (ISSF)

Thai Union Europe, John West’s parent company, is a founding member of the ISSF. ISSF’s mission is to support and facilitate science-based initiatives for the long-term conservation and sustainable use of global tuna stocks, which includes reducing bycatch and promoting tuna ecosystem health.
