Tesco Seafood

Lacks transparency

Lacks transparency. Publishes some details, but doesn't show its workers are paid and treated fairly.

Last researched 30 October 2026 · 9 sources

Tesco's own-label fish and seafood: canned, chilled and frozen, sold in the UK.

Tesco Seafood's supply chain was linked to forced labour in 2023, which it has only partly acted on, and it has no full independent audit.

Why it's graded Lacks transparency

  • Not met: Meets 1 of 6 Good requirements.
  • Holds the grade back: It has 4 red flags: no evidence of a living wage, unaudited production in high-risk countries, forced or child labour and fish and seafood it can't trace to the boat or farm. Two or more red flags means a poor grade.
  • It isn't Harm on record: the most serious problem on its record (forced labour link, last recorded in 2023) was a link through a supplier, which the company has only partly acted on.
  • Lacks transparency is still a poor grade: in supply chains like this, workers who can't be seen to be treated fairly are usually underpaid or unprotected.

How grades are decided


Good requirements 1 of 6

  • Not met: Pays a living wage, or holds a strong fair-pay certificationLiving wage: no evidence
  • Not met: Respects worker rightsMost of its products are made in countries such as China and Thailand, where unions are heavily restricted, and it has no full supply chain audit.
  • Not met: Supply chain independently audited or certified, or at least 80% made in countries with strong labour standards
  • Not met: No child or forced labour findings or links
  • Met: Names the factories or farms that make its products, or is fully certified by a scheme that holds and audits that listPublishes its supplier list
  • Not met: Traces its catch to the boat or farm and has crews' or farm workers' conditions checked independently

Red flags 4

  • Red flag: No evidence it pays a living wage
  • Red flag: Made mostly in countries with poor worker rights, without a full independent audit of its supply chain
  • Red flag: Forced, slave or child labour found in or linked to its supply chain
  • Red flag: Relies on fish and seafood it can't trace to the boat or farmShown to explain the grade. It isn't one of the 3 red flags that set it.
  • Red flag: Fails its category's raw-material check (means Lacks transparency)

Evidence

What we found

  • Risk across the industry, not a finding about this company: fishing fleets and processing plants have some of the worst documented forced labour, including trafficked crews held at sea for years.
  • Publishes supplier list
  • Relies on fish and seafood from fishing boats and farms, where crews and farm workers, often migrants recruited into debt, have been held for months or years, beaten and denied pay, out of reach of factory audits. It hasn't shown any steps to trace its fish and seafood to the boat or farm or have the conditions of the people who catch or farm it checked, so it's graded Lacks transparency until it does.

Research notes Tesco publishes a list of its first-tier food sites; the seafood sites named on it are in the UK (3), the US (2, Alaska salmon canneries), Vietnam, Ecuador, Turkey, Spain and Iceland (1 each), so these shares cover only its direct seafood suppliers and leave out products bought through importers. Its Ocean Disclosure Project profile names fisheries and farms by country (farmed salmon from Norway, UK and Ireland; prawns from Vietnam and Saudi Arabia; pangasius from Vietnam), but not boats. It targets 100% MSC tuna by 2025; some lines are ASC or BAP certified. No vessel-level crew checks such as RFVS are reported.

Credible reports that haven't been confirmed by a regulator, completed investigation or the company. They're shown for your information and don't affect the grade.

  • Tesco did not answer a 2018-19 Business & Human Rights Resource Centre survey of 35 tuna companies and supermarkets on slavery in tuna supply chains; it said it had missed the survey and pointed to its Seafood Task Force membership (Eco-Business, 2019). Source
