Farmed Pig Pen Hygiene and Disease Welfare

Pen hygiene management directly affects disease burden and welfare in pig housing, with cleaning and disinfection between batches being critical.

Key Facts

All-in all-out production with thorough disinfection between batches breaks disease cycles
Bacteria including Streptococcus and E. coli persist in organic matter without thorough cleaning
Continuous housing without disinfection allows disease to accumulate over batches
High-pressure washing followed by disinfection and drying is the standard approach
Disinfectant efficacy is affected by temperature and residual organic matter

Welfare Considerations

Pigs in inadequately cleaned housing accumulate pathogen exposure from previous batches, increasing disease incidence and welfare harm throughout the production cycle. All-in all-out production with thorough cleaning and disinfection is the most effective disease prevention management practice. Hygiene standards are fundamental to welfare management.

What You Can Do

Support welfare auditing that includes hygiene practice assessment
Advocate for all-in all-out housing as the standard for pig production
Choose pork from farms with documented hygiene protocols
