What to check

Before you eat crawfish.

  1. Cook crawfish until pearly and opaque

    The FDA asks for most seafood cooked to 145°F, and says shellfish such as shrimp and lobster are done when the flesh is pearly and opaque. Health Canada's chart gives 74°C (165°F) for shellfish. FDA

  2. Don't leave the boil out for hours

    The FDA says never to leave seafood out of the fridge for more than 2 hours, or more than 1 hour above 90°F. A spread left out through a long, hot afternoon goes past that. FDA

  3. Count crawfish in your weekly fish

    The FDA suggests 8 to 12 ounces of Best Choices a week in pregnancy, and a serving is 4 ounces. Shrimp, crab or crawfish from the same boil all count. FDA
