- Fire: Piggery sheds contain electrical wiring, gas heaters, feed dust and bedding material - all creating significant fire risk. A shed fire typically results in total loss of the structure and all animals inside. Feed mills and grain storage on piggery sites add further fire exposure.
- Ventilation & Climate Failure: Pigs are highly susceptible to heat stress. A ventilation breakdown in summer can cause mass mortality within hours, particularly in farrowing and grower sheds.
- Disease & Biosecurity Breach: Porcine Reproductive and Respiratory Syndrome (PRRS), African swine fever (ASF), porcine epidemic diarrhoea (PED) and other diseases can devastate herds and trigger government-imposed quarantine and depopulation orders.
- Power Failure: Piggeries rely on continuous power for ventilation, automated feeding, watering, climate control and effluent pumping. Extended outages without backup generation are potentially catastrophic.
- Effluent System Failure: Piggery effluent management is heavily regulated by state EPAs. A lagoon breach, pipeline failure or pump breakdown can result in environmental contamination, prosecution and substantial remediation costs.
- Storm & Flood: Large-span piggery sheds are vulnerable to wind damage. Flooding can inundate sheds, destroy feed stores and overwhelm effluent systems.
