Is basa considered clean or unclean?

Basa fish, often farmed in Vietnam, is sometimes considered unclean due to concerns about water quality in aquaculture practices and potential contamination with pollutants. However, it can be safe to eat if sourced from reputable farms that adhere to safety and environmental standards. Ultimately, perceptions of cleanliness can vary based on individual beliefs and the specific sources of the fish. It's essential to research and choose fish from sustainable and certified suppliers.
