Which Fish Contain the Most Microplastics — and Why You Should Avoid Eating Them

⚠️ What Happens If We Eat Microplastics?

Although the long-term health effects are still under investigation, there are several known risks:

• Inflammation: Microplastics may trigger immune responses and inflammation in the gut.

• Chemical Exposure: They can carry toxic chemical additives such as:

  • Bisphenol A (BPA) – An endocrine disruptor that mimics hormones and interferes with the hormonal system.

  • Phthalates – Linked to fertility issues, obesity, respiratory problems, and neurodevelopmental disorders in children.

• Pathogen Transport: Microplastics can act as carriers for bacteria, viruses, and other pathogens.

🐠 Should You Stop Eating Fish?

Not necessarily — but it’s wise to limit consumption of species that are known to have high microplastic concentrations, especially:

• Sardines (often eaten whole)

• Shellfish like oysters and crabs (eaten with internal organs)

When possible, opt for larger fish that are filleted (reducing organ consumption) and choose responsibly sourced seafood from cleaner waters. Reducing overall plastic pollution is also crucial for long-term change.
