Before buying absolutely anything unusual from Asian stores, it’s better to do some research. It turns out that you should avoid eating swai fish, also known as panga, pangasius, sutchi, cream dory, striped catfish, Vietnamese catfish, tra, basa, iridescent shark, and Siamese shark, though it’s not a shark at all. Because there’s a high likelihood (70-80%) that it contains vibrios (bacteria) and various other nasty things, including poisonous substances. Probably in minimal amounts, but they accumulate.
