Rianxeira

• 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.
• Owns or runs its own production
• 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 Rianxeira is the main brand of Jealsa, which cans tuna at its own plants in Boiro and A Pobra do Caramiñal in Galicia, Spain, and also makes Mercadona's Hacendado tuna. The group has run a tuna plant on Guatemala's Pacific coast, operates in Brazil through Crusoe Foods, and has tuna vessels in the Atlantic. It is an ISSF member but publishes no vessel or supplier list, no modern slavery statement and no independent checks on crews of the boats that catch its tuna.
