Greenseas
Lacks transparency. Publishes some details, but doesn't show its workers are paid and treated fairly.
Last researched 23 October 2026 · 7 sources
Australian canned tuna brand owned by Kraft Heinz.
Greenseas's parent, Kraft Heinz Australia, scored 8/100 in the 2026 KnowTheChain benchmark, and there's no proof it pays more than the legal minimum, which in Thailand is below a living wage.

Why it's graded Lacks transparency
- Not met: Meets 2 of 6 Good requirements.
- Holds the grade back: It has 3 red flags: no evidence of a living wage, a failing or very low rating (KnowTheChain 8/100 in 2026, for the company it's rated with) 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, because there's no serious confirmed problem on its record.
- 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.
Good requirements 2 of 6
- Not met: Pays a living wage, or holds a strong fair-pay certificationLiving wage: no evidence
- Not met: Respects worker rightsJudged on where its products are made: worker rights are poorly protected in Thailand.
- Met: Supply chain independently audited or certified, or at least 80% made in countries with strong labour standards
- Met: No child or forced labour findings or links
- Not met: Names the factories or farms that make its products, or is fully certified by a scheme that holds and audits that list
- Not met: Traces its catch to the boat or farm and has crews' or farm workers' conditions checked independently
Red flags 3
- Red flag: No evidence it pays a living wage
- Red flag: Failing or very low score on an independent rating: KnowTheChain 8/100 (2026, the company it's rated with)
- 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 2 red flags that set it.
- Red flag: Fails its category's raw-material check (means Lacks transparency)

Where it's made

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.
- Modern slavery statement
- Independent social audits of all its main factories
- 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 Greenseas tuna is caught in the Western and Central Pacific, gathered by several suppliers and processed by unnamed third-party manufacturers in Thailand. Kraft Heinz obtained SMETA audits of the Thai plants, which found no signs of modern slavery, but publishes no supplier or vessel list; onboard monitoring and captain statements for fishing boats were only recommended. The FAD-free and dolphin-safe claims are environmental.
