Why Recombinant Bovine Somatotropin is flagged
See recombinant-bovine-growth-hormone-rbgh for full detail. Key concerns: rBST elevates IGF-1 in milk; elevated blood IGF-1 is associated with breast, prostate, and colorectal cancer risk in epidemiological studies. Animal welfare: increased mastitis (up to 25-50% higher rates), lameness, and antibiotic use. The Codex Alimentarius Commission declined to endorse rBST safety MRLs in a historic 33-29 vote. Health Canada rejected rBST approval in 1999 after finding it caused significant animal health problems requiring increased antibiotic use.
