Fish is often touted as a healthy source of protein, rich in omega-3 fatty acids, and essential nutrients. However, not all fish species are the same. Due to pollution, farming methods, and environmental changes, some fish species contain high levels of toxins that can pose serious health risks.
Before you add fish to your shopping cart, check out this list of the 12 most contaminated fish commonly found in stores. Knowing what to avoid can help you protect your health.
1. Farmed Tilapia
Farmed tilapia often come from overcrowded fish farms where they are fed unnatural diets. Many farms use antibiotics and chemicals, and studies have found high levels of contaminants in farmed tilapia from certain countries.
2. Farmed Atlantic Salmon
The majority of commercially available Atlantic salmon comes from aquaculture. Farmed salmon is often exposed to pesticides, antibiotics, and synthetic dyes to enhance its pink color. Tests have shown that farmed salmon contains higher concentrations of PCBs (polychlorinated biphenyls), which have been linked to cancer.
