Eating sushi while pregnant

Sushi and other dishes made with raw fish are fine to eat when you're pregnant as long as the fish used to make it has been frozen first.

This is because, occasionally, fish can contain small parasitic worms that could make you ill. Freezing raw fish kills the worms and makes it safe to eat.

Whether it's ready-made or prepared on the premises, sushi sold in shops or restaurants should be fine to eat as the raw fish used to make it must have been frozen at minus 20°C for at least 24 hours.

If you make your own sushi at home, freeze the fish for at least 24 hours before using it. Some raw fish used to make sushi, such as smoked salmon, doesn't need to be frozen before it's used as smoking the fish kills any worms that might be in it. Other methods, such as salting or pickling, are also used to make raw foods safe to eat.
