These live Asian swamp eels were imported from southeast Asia and sold in an urban food market in the U.S. Raw or undercooked Asian swamp eels could transmit a parasitic infection called gnathostomiasis to consumers, and wild eels could become widespread in some U.S. waters.
How can the spread of Asian swamp eels be prevented?
The USGS focus is to document the eel’s geographic distribution and to learn as much as possible about its behavior and biology. The resulting information is considered critical in helping to develop strategies aimed at containing or controlling its spread. Meanwhile, catching and transporting Asian swamp eels for use as bait, food, or aquarium pets is highly discouraged.

Non-native or introduced populations of Asian Swamp Eels (family: Synbranchidae) exist in the wild in parts of Florida, Georgia, and Hawaii. This video shows predatory behavior of captive individuals.
