Contamination & Safety
Haddock · 75Chicken Breast · 85Haddock carries a low but real risk of mercury and microplastics, while chicken breast's main risk is bacterial contamination and antibiotic residues.
Tradeoff
Ocean pollutants versus agricultural antibiotics are two very different safety profiles to weigh.
Why it matters
Long-term accumulation of heavy metals or antibiotic resistance are both undesirable health outcomes.
Real-world impact
You can safely eat chicken breast daily; haddock is best limited to a few times a week to minimize mercury exposure.
