Risk profile
Safety & processing
Both whole cuts of lamb and salmon are minimally processed. The real concern is farming practices: feedlot lamb and farmed salmon both have worse nutritional profiles and higher contaminant risks than their grass-fed or wild-caught counterparts.
Lamb
Heterocyclic amines from high-heat cooking
mediumCharring or grilling lamb over open flames creates carcinogenic compounds. Slow cooking or avoiding well-done meat reduces this.
Antibiotic and hormone residues
lowConventional lamb farming uses antibiotics, though less than beef or pork. Grass-fed options minimize this risk.
Salmon
Mercury and heavy metal accumulation
mediumLarger or farmed salmon can accumulate mercury and PCBs. Wild-caught Alaskan salmon is typically very low in these contaminants.
Microplastics and ocean pollutants
mediumAll seafood contains trace microplastics today. Varying your protein sources prevents over-accumulation.
