A study says high levels of "forever chemicals" may be in seafood. Forever chemicals are man-made toxins. They stay in our blood and lead to health issues. These include cancer and kidney problems. Researchers said we need safety guidelines for these chemicals in seafood, especially for marine creatures like prawns and lobster. People who love sushi and prawn cocktails may have to change their diet and eat less seafood.

Forever chemicals were created in the 1930s. Today, they are found in food packaging, food wrappers, and food containers. Over the decades, the chemicals have entered our food chain. A professor wants people to enjoy seafood, but also to be aware of the risks. She said: "Our recommendation isn't to not eat seafood." She thinks it is important for us to understand more about what is in the food we eat.
