“Fish may be naturally contaminated with mercury through environmental or industrial processes,” Johnson-Arbor explained. “When mercury enters waterways, it is consumed by fish and bioaccumulates up the food chain. Larger fish, including tuna, swordfish and sharks, are more likely to have higher levels of mercury than smaller fish.”

You might think of mercury as the silver beads in an old-fashioned glass thermometer, but Johnson-Arbor says mercury in fish is different. “The mercury found in fish is usually methylmercury, an organic form of mercury,” she notes. “Methylmercury is a powerful neurotoxin that can cause damage to the developing brain of fetuses, infants and children.”
