How independent welfare auditing works, its limitations, and what makes audit systems credible and effective for animal welfare outcomes.
Welfare auditing is the principal mechanism through which certification claims are verified, but audit quality varies dramatically. Audits that measure only physical resources - space, equipment, water provision - miss important behavioral and health welfare outcomes. Audits that are announced in advance allow farms to temporarily improve conditions for the inspection visit. Auditors who visit the same farms repeatedly may develop relationships that compromise independence. Effective welfare auditing requires animal-based outcome measures, unannounced visits, auditor rotation, and genuine consequences for non-compliance including delisting.
