I like to give you one example. This is a popular Japanese dish. Its name is sushi. Japanese people use rice and mostly raw fish, including tuna to prepare sushi. Although sushi occasionally contains cooked seafood, it is mostly made using raw seafood, giving the elements a variety of names. Sashimi is one of them.

Is it safe to eat raw tuna?

When considering seafood, particularly tuna, thrives in its natural environment (the sea). Also, it is very important to treat properly throughout the process.

If you are pregnant or have a high tolerance for mercury, this could be harmful to you. Raw tuna also has the potential to harm your teeth over time. It may result in tooth decay or gum disease. For this reason, brushing your teeth after consuming any kind of fish is crucial.
