What research says

Found in some samples or products

These come from where it was grown, how it was processed or cooked, or what it was made into. They are not about the ingredient itself, so the signal does not count them.

  • Foodborne germs in fish3

    Tilapia can carry germs like Salmonella and Listeria, so scientists say it needs closer monitoring.

  • Food poisoning from fish4

    Plesiomonas shigelloides, a germ found in tilapia, has been linked to outbreaks of stomach illness.

  • Antibiotic residues in farmed fish5

    Farmed tilapia can carry antibiotic residues that may reach people who eat the fish.

  • Metal levels in fish6

    Nile tilapia from Egypt's Rosetta Nile carried metals like mercury and lead, and antimony levels suggested a possible health risk.

  • Toxin removal by depuration7

    Tilapia can build up saxitoxins, but holding the fish in clean water can remove them.

  • Heavy metals in fish8

    Tilapia from a landfill had lead and other metals in their muscle, and lead was above food safety limits.

  • Mercury in fish9

    Tilapia from a mining-area dam held more mercury in the dry season, but levels in the eaten part stayed within safe limits.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
