Where were you? Mexico? or France? Apparently there is a big movement telling people not to eat these fish because they could be dangerous.
Pangas are teeming with high levels of poisons and bacteria. (industrial effluents, arsenic, and toxic and hazardous by-products of the growing industrial sector, polychlorinated biphenyls (PCBs), DDT and its metabolites (DDTs), metal contaminants, chlordane-related compounds (CHLs), hexachlorocyclohexane isomers (HCHs), and hexachlorobenzene (HCB)). The reasons are that the Mekong River is one of the most polluted rivers on the planet and this is where pangas are farmed and industries along the river dump chemicals and industrial waste directly into it. To Note: a friend lab tests these fish and tells us to avoid eating them due to high amounts of contamination. Regardless of the reports and recommendations against selling them, the supermarkets still sell them to the general public knowing they are contaminated.
