Welfare auditing provides assurance that farm welfare standards are being met, but auditing methodology, frequency, and independence determine whether audits translate to real welfare improvement.
Welfare auditing quality varies enormously and the gap between auditing as a paper exercise and auditing as genuine welfare verification is significant. Audits that check inputs (space allowances, enrichment provision) without measuring animal-based outcomes can be gamed by producers who meet minimum requirements on audit day without achieving good welfare year-round. The shift toward animal-based outcome measures including lameness prevalence, injury rates, and mortality data represents a genuine improvement in audit quality because these outcomes are harder to manipulate for a single audit visit. Continuous monitoring through CCTV and sensor data provides the surveillance depth that periodic auditing cannot achieve.
