Gestation Crate Phase-Out: Progress and Remaining Challenges

Gestation crates for sows are being phased out across many markets, but the transition is incomplete and the welfare timeline reveals both progress and persistent challenges.

Key Facts

Gestation crates confine pregnant sows in stalls too small to turn around for most of their 16-week gestation — a practice that prevents virtually all natural behavior and causes severe frustration and chronic stress
The EU banned continuous gestation crate use in 2013 (allowing confinement only for the first 4 weeks of gestation) — but enforcement varies and some member states continue non-compliant practices
Over 200 major food companies including McDonald's, Walmart, and Subway have committed to eliminating gestation crates from their pork supply chains — most by 2025
Progress on corporate commitments has been slower than pledged: a 2023 audit found approximately 60% of companies with 2022 commitments had not yet fulfilled them
California Proposition 12 (2018) set the most stringent US standards, requiring that pork sold in California come from operations using group housing — a significant market driver given California pork consumption
Group housing systems that replace gestation crates have their own welfare variables: fighting at feeding can cause injury, space inadequacy can concentrate stress, and management skill is critical for good outcomes
The welfare benefit of eliminating gestation crates is real and substantial: sows in group housing show lower cortisol levels, more natural behavior expression, and better welfare indicators than sow in continuous confinement

Welfare Considerations

Gestation crate welfare progress represents one of the most significant farm animal welfare policy advances of the past two decades — a practice that welfare science uniformly condemned is being eliminated through a combination of regulatory bans, corporate commitments, and consumer awareness. The challenge is ensuring that commitments are fulfilled: the 2023 audit showing many companies behind on commitments reveals the need for verification and accountability beyond pledge signing. Consumers who purchase pork from companies with fulfilled commitments and avoid pork from companies that have signed but not implemented create market pressure for follow-through. The transition to group housing also requires welfare-conscious management to realize the potential welfare benefit — group housing with poor management can reproduce some stress outcomes of gestation crates through fighting and competition.

What You Can Do

Check which pork companies have fulfilled their gestation crate commitments and purchase from those that have versus those still using crates
Support organizations including HSUS and CIWF that audit and publicize corporate commitment follow-through on gestation crate phase-outs
Advocate for California Proposition 12 enforcement and similar legislation in other states that creates regulatory requirements beyond voluntary commitments
Reduce overall pork consumption and concentrate purchases on welfare-certified products from verified group-housing operations
Engage with food service companies about gestation crate policies in their pork supply chains — food service is a significant market segment that can drive supplier change
