Tag: Arsenic in fish

According to the World Health Organization, seafood is a major source of dietary arsenic, yet the form of arsenic is the key determinant of its toxicity. This means that when asking, 'Do sardines have more arsenic than salmon?', the answer is more complex than a simple yes or no and requires understanding the different types of arsenic found in fish.

While it's true that seafood is the largest dietary source of arsenic for many people, the vast majority of this element in fish exists in a much less toxic organic form. This fact is critical for understanding the actual health implications of whether and why fish have arsenic in them.
