Where should the biosecurity vehicle spray wash be located relative to the entry gate and employee parking lot on a poultry estate?

To prevent pathogens from entering a commercial poultry estate, the physical arrangement of the entrance is a primary biosecurity line. The vehicle disinfection spray wash (or chemical spray gate) must be placed at the outermost perimeter boundary, directly at the single entry gate. It must be positioned such that any vehicle (whether a feed truck, egg loader, or visitor car) must pass through it *before* reaching the security office, farm parking lot, or administrative offices. This ensures that no unsanitized tire or undercarriage touches the internal asphalt roads. The parking lot for employee and visitor personal vehicles must be located outside this clean perimeter, forcing staff to walk through a secondary shower-in facility. Farmers can study farm biosecurity zoning in the Poultry Encyclopedia, purchase automated vehicle wash systems on Poultry Plaza, monitor daily egg prices on Poultry Rates, and trade with certified biosecure operations on Murghi Mandi.
