There are multiple opportunities to detect tapeworm cysts and larvae before the sushi makes it to our plate.
No, it's extremely rare to contract a parasitic infection from eating sushi or sashimi in Australia.

Pacific salmon are ingrained in the culture and economy of Canada. They are also a key link between ocean and land. But what happens if a pipeline failure contaminates their habitat?
Cod and other fish may be unintentionally caught by pulse trawlers.
An expert reviews the research for and against the use of electric pulse trawlers.
The ocean is getting warmer and more acidic but changing our diet could help us cope.
Canned tuna is an Australian pantry staple.
Australians love canned tuna. Here's our handy guide to finding the most sustainable options for you (and your cat).
The sea remains the least explored habitat on our blue planet.
There's plenty of evidence that even fish have feelings.
Pacific seabirds, such as this Great Blue Heron, can accumulate mercury in their bodies from the fish they eat.
Mercury levels in seabirds living off the coast of British Columbia have been stable in recent years. New research suggests that this may be due to changes in their diet, not pollution control.
The evidence shows that both low and high fat diets can reduce your risks of cardiovascular disease – if they are plant-based.
From donuts to avocados, food impacts your heart health. Here we delve into the science of how to eat -- to reduce your chances of cardiovascular disease.

Reef Life Survey, a citizen science project where hundreds of volunteer scuba divers survey thousands of ocean sites, has revealed new insights into marine mysteries.
It really should be consumed at least twice a week.
A study of middle-aged British women shows that omega-3 has beneficial effects on gut health.
The offspring of mice who don't get enough DHA during pregnancy are more likely to have pups that display schizophrenia-like symptoms.
Snapper is one of the fish under New Zealand’s Quota Management system.
New Zealand’s fisheries are considered among the best managed in the world, but this perception doesn't match the facts.
Plastic trash on San Francisco’s Ocean Beach.
A new study shows that anchovies – key food for larger fish – are attracted to plastic trash because it smells like food. This suggests that toxic substances in plastic could move up through food chains.
Tiny hairs cover the bodies of honeybees — including this one dusted in pollen — that allow them to detect molecular “fingerprints” similar to how home security sensors work.
Bees and home security cameras use the same complex techniques to monitor their environments.
A beached hoodwinker sunfish, the new species described by researchers from Murdoch University.
A four-year puzzle has ended with the discovery of a new species of sunfish. These famously strange-looking animals are the largest bony fish in the oceans.
A shark’s nose is chemosensory only, and it doesn’t join up to the back of the throat like ours does.
Sharks can't sneeze like we do, but they can do other cool tricks -- like making their stomach stick out of their mouth to get rid of unwanted stuff.
A tank can give a good idea of what will happen out in the wild.
A new study suggests the benefits of a boost to marine plant growth from increased carbon dioxide will be cancelled out by the increased stress to fish species.
Fish leave bits of DNA behind that researchers can collect.

Animals shed bits of DNA as they go about their lives. A new study of the Hudson River estuary tracked spring migration of ocean fish by collecting water samples and seeing whose DNA was present when.
