A well balanced, nutritious diet and regular exercise are vital factors in a healthy lifestyle.

Seafood, which includes fish and shellfish (eg prawns, oysters and mussels) is very good for your health.

Seafood is high in protein, high in vitamins and minerals, low in saturated fat, and contains Omega 3 fatty acids that benefit your brain, eyes and heart.

Seafood safety

Seafood in Australia is very safe to eat and attributable to very few foodborne illness outbreaks due to strict regulations and testing. For most people seafood is safe if it is handled and stored correctly. However if you are pregnant or have a young family, it’s best to consume fish that contains low levels of mercury as fish with high levels of mercury can harm the brain development of babies and young children.

Seafood is a favourite food for many people, especially during the warmer months. However to avoid food poisoning, seafood needs special care from the time it is bought to the time it is consumed.

Follow these tips to make sure your seafood is safe to eat:


  • Only buy seafood from reputable retailers. Seafood from unknown suppliers may not have been handled properly and could cause food poisoning
  • Take a cooler bag or Esky to the store or fish markets. Ask the fishmonger if they could pack ice with the seafood (they are not obliged to supply ice)
  • Purchase seafood with a fresh sea smell
  • For whole fish, the gills should be bright pink-red and firm and the flesh should be bright, not dull
  • For sushi, raw fish must be sashimi-grade, very fresh and of the highest quality
  • For whole prawns, the heads should be firmly attached and the shell tight and shiny
  • Opened oysters should look wet and smell of fresh sea
  • For unopened oysters and mussels, shells must be closed or close when tapped
  • Purchase seafood last


  • Put seafood into the fridge or freezer as soon as you get home, don’t leave it in the car or on the kitchen bench
  • Store prawns in an airtight container, or covered tightly with plastic wrap, away from other food in the coldest part of fridge and leave in the shell for as long as possible

Preparation and eating

Recreational fishing
