The USDA researchers note that there are currently no regulatory limits on the amount of

Numerous studies have shown that industrial pollutants such as
flame retardant chemicals and mercury found in fish (such as tuna) may impair a baby's cognitive development, and is associated with reduced cerebellum size in newborns; methylmercury
contamination in fish generally outweighs DHA benefits on brain development measured as children IQ.
