Description
Luiz Drude de Lacerda and Moises Fernandes Bezerra survey in 2026 mercury levels in inland fish and farmed fish from northeastern Brazil. Their work is the first regional check of its kind, covering fourteen species from rivers plus farmed tilapia. Rapid growth of inland fishing and fish farming makes regular safety checks more pressing.
Mercury levels overall were very low and well below food safety limits used in Brazil and abroad. Meat-eating species such as piranha from river systems carried more mercury than plant feeders, as expected. Farmed tilapia ready for market held less mercury than young fish, likely because fast growth spreads the metal through more tissue. Even heavy fish eaters faced very low estimated exposure.
