Fish is often praised as a healthy source of protein, packed with omega-3 fatty acids and essential nutrients. But not all fish are created equal. Due to pollution, farming practices, and environmental changes, some types of fish contain high levels of toxins that may pose serious health risks.
Before you add fish to your grocery cart, check this list of the 12 most contaminated fish commonly found in stores. Knowing what to avoid can help you protect your health.
1. Tilapia (Farmed)
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 pollutants in farmed tilapia from certain countries.
2. Atlantic Salmon (Farmed)
Most Atlantic salmon sold in stores is farm-raised. Farmed salmon is often exposed to pesticides, antibiotics, and synthetic colorants to enhance its pink color. Tests have shown farmed salmon contains higher levels of PCBs (polychlorinated biphenyls), which are linked to cancer.
