Where to buy swai fillets?

I’m having a hard time locating swai fillets that have not been treated with sodium tripolyphosphate. Does anyone have a source?

Trader Joe’s sells frozen swai fillets which I believe are not treated…

That’s where I used to get them, but TJ stopped selling those a while ago. :frowning:

i’ve gotten them from super king but i doubt they were non STP, which is ironic, because swai is known for its naturally moist texture.
