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 hidden supply chain 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.

How grades are decided


Good requirements 2 of 6

  • Not met: Pays a living wage, or holds a strong fair-pay certificationLiving wage: no evidence
  • Met: Respects worker rights
  • Not 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: Hidden supply chain: no certification, independent audits or supplier list
  • 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)

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.
  • Makes part of its range in its own 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 Bolton says Cuca is made in two plants in Galicia, Spain, where its sardines are cleaned and packed by hand; in 2026 some Cuca sardine cans were found labelled as packed in Morocco, without the packer named. Its sardines were reported in 2014 to come from fisheries off Galicia and northern Portugal. Bolton's published tuna vessel list and ISSF reporting cover Rio Mare, Palmera and Saupiquet, not Cuca, and no MSC certification, crew checks or audits are reported for Cuca's range.
