Swai Fish: Facts You Didn’t Know

Fish has become a crucial part of the daily diet of the people around the world and swai fish has presented itself as an inexpensive and readily available option. However, before you start adding this fish to your diet, it is important to know where it comes from and some of the potential risks posed by this imported fish.

What is Swai Fish?

Swai fish is actually the common name of the iridescent shark, a type of catfish that is native to Southeast Asia. Bearing the scientific name Pangasianodon hypophthalmusthis fish is widely cultivated in that region of the world, and exported to the United States. Swai is a white-flesh fish, with a flaky texture that makes it ideal for broiling, grilling or frying. The flavor is also quite mild, making it a popular option for those who don’t want their fish to taste too briny.

In the United States and elsewhere, swai fish is often marketed as a river-farmed catfish, but that name can be misleading. Much of the swai fish that is exported to other countries is bred in fish farms in Vietnam and other areas of Southeast Asia, with low levels of regulation and health standards, which is why most experts do not recommend eating swai fish.

Why is it Not Safe to Eat?

Although factory-farmed fish are not inherently unhealthy, swai fish has developed a particular reputation as being below quality standards. Numerous health organizations around the world have criticized the water quality of Vietnamese fish farms, as it can be filled with bacteria and other chemical pollutants. There are many reports of swai fish being contaminated with trace minerals and heavy metals, largely due to the conditions in which they were raised.

Even more troubling are the reports of the food being given to these fish before they are farmed and exported to restaurants around the world. Like many catfish, swai are not picky about the food they eat and are often labeled as bottom-feeders. As such, swai fish in Vietnamese fish farms are occasionally fed food waste and other garbage from local restaurants and from the fish farms themselves, which greatly increases the chances of toxins being introduced into the flesh of the fish. With a lack of regulation and a track record of being unhealthy or contaminated, swai fish should be avoided, despite the low price. There are plenty of other white-flesh fish and pescetarian options that are better for your overall health.
