USDA Safe Internal Temp
63°C (145°F) (Some cooks prefer 49–52°C to avoid drying it out, but that falls below the FDA-recommended minimum) 63°C (145°F) (Rare-seared ahi, ~46°C/115°F, is common but below the FDA-recommended minimum -- relies on the fish being sushi/sashimi-grade and previously frozen to control parasites, which does not address bacterial safety)
