Your Favorite Seafood May Contain Hazardous Chemicals
Shellfish Contain Higher Levels of Hazardous Chemicals
A new study conducted by Dartmouth College has found that seafood consumption, while presenting health benefits, can also expose consumers to potentially dangerous contaminants. In the study published in the journal Exposure and Health, researchers surveyed 1,829 New Hampshire residents to analyze the impact of seafood intake on their health. The study revealed that the most commonly consumed seafood varieties such as salmon, haddock, shrimp, and canned tuna are contaminated with 26 different forms of per- and polyfluoroalkyl substances (PFAS).
Interestingly, researchers discovered that shellfish, including lobster and shrimp, contained higher concentrations of PFAS compared to fish.
This study raises concerns about the potential health risks associated with consuming seafood, especially for vulnerable populations such as pregnant individuals and children.
The Dangers of PFAS
The acronym PFAS stands for per- and polyfluoroalkyl substances, also known as forever chemicals. These contaminants are called forever chemicals because they persist in the environment and can remain in our bodies for thousands of years. The consumption of PFAS through food and beverages can be harmful to human and animal health, as they have been linked to negative effects on cholesterol, liver enzymes, the immune system, vaccine response, and an increased risk of cancer.
The Impact on New Hampshire Residents
According to the study, New Hampshire residents consume more seafood than the average American. This higher consumption puts them at risk of elevated PFAS exposure, which can be hazardous to health. However, the study does not advocate for completely abstaining from seafood consumption. Instead, it emphasizes the importance of understanding the risks and benefits associated with seafood consumption to make informed dietary choices.
Efforts to Address PFAS Contamination
The Environmental Protection Agency (EPA) and the Biden-Harris Administration have acknowledged the importance of tackling PFAS contamination. A recently issued national drinking water standard and a $1 billion investment aim to make drinking water safer for millions of Americans.
While these initiatives represent a step forward, comprehensive actions are still needed to improve water quality globally.
Eating Like Salmon: A Healthier Choice?
The study suggests that consuming smaller fish species, like salmon, may be a healthier alternative to consuming larger fish. Smaller fish have shorter lifespans and are less exposed to aquatic toxins, including PFAS. These toxins tend to accumulate higher up the food chain. Therefore, opting for smaller fish may reduce the risk of PFAS exposure.
The Importance of Informed Choices
The study’s corresponding author, Megan Romano, a professor of epidemiology at Dartmouth, stresses the significance of understanding the risk-benefit trade-off associated with seafood consumption. By comprehending the potential risks, especially for vulnerable populations, individuals can make more informed decisions about their diets.
Conclusion
The Dartmouth College study has shed light on the presence of hazardous chemicals in seafood, with shellfish particularly affected. While further efforts are required to address PFAS contamination, individuals can make informed choices about their seafood consumption, considering the potential risks and benefits.
