Sushi & raw fish

Okay in moderation — there are limits worth knowing.

You can eat sushi if the raw fish was frozen first (as most is in the UK), which kills parasites. Avoid home-made raw-fish sushi that hasn't been frozen.

Official guidance is to steer clear during pregnancy.

Avoid raw or undercooked fish and shellfish, including raw sushi and sashimi, because of harmful bacteria and parasites. Cooked sushi is fine.
