Poultry Biosecurity in Zimbabwe: Practical Farm Guide
Biosecurity is any measure that prevents disease from entering or spreading on your farm. It costs almost nothing but prevents losses that run into thousands of dollars. In Zimbabwe, where viral disease pressure (Newcastle, IBD, Marek's) is high and veterinary response time is slow, biosecurity is your first and most important line of defence.
The Three Zones
Dirty zone (outside the farm boundary): vehicle and visitor traffic stops here. Transition zone (farm entrance): foot dip with 3% caustic soda, change of clothing and footwear, handwash. Clean zone (inside sheds): only farm staff in designated shed clothing. Visitors and buyers should never enter the clean zone during a cycle. This is not bureaucracy. A single contaminated boot sole has caused Newcastle outbreaks that killed entire flocks.
Daily Biosecurity Checklist
Change clothing before entering sheds. Disinfect footwear in foot bath (change solution every 48 hours or when visibly contaminated). Remove dead birds immediately. Never leave overnight. Record cause of death and disposal method. Check for rodent activity (rat poison stations and traps). Inspect shed perimeter for wild bird entry points. Confirm no unauthorised visitors in clean zone. Log all these items daily, FarmIQ's biosecurity module records this digitally.
After a Disease Outbreak
Depopulate: all birds must leave together. No partial clears, as this leaves reservoirs of infection. Cleanout: remove all litter (do not compost on-site during disease period). Wash: high-pressure water removes organic material that shields pathogens. Disinfect: Virkon S (1%) or iodine-based disinfectant applied to all surfaces, wait 30 minutes. Fumigate: formaldehyde or glutaraldehyde fumigation if ND or Marek's is confirmed. Downtime: minimum 21 days empty before restocking. Report: notify DVS (Department of Veterinary Services) if Newcastle or any HPAI is suspected. This is legally required and they may provide free diagnostics.
Litter Management
Deep litter system: 8–10cm of wood shavings or rice hulls. Never use sawdust from treated timber (toxic). Turn litter every 5–7 days. Remove wet litter around drinkers immediately. At batch end: remove all litter, do not re-use across cycles without proper composting. In-house composting between cycles (heating litter to 55°C+ for 5 days) can sterilise it for re-use in low-disease-pressure environments, but is not recommended after a disease event.
