Watch: Are You Eating Fake Fish?

• If you’re really worried, stick to cooked sushi varieties.

• Saltwater fish are less likely to carry parasites.

• Atlantic fish are less likely to carry them than Pacific fish.

• Stick to sashimi-grade fish.

Watch: Mercury Levels in Sushi

Any raw fish or meat product carries some risk, so be sensible, stick to sources you trust, and if you’re not sure about it – don’t eat it!
