Identity

A physical isolation and visitor management protocol requiring personnel to undergo a complete clothing change upon entry and exit.

Overview

Shower-in/Shower-out facilities represent a physical isolation protocol requiring a complete clothing change to prevent viruses carried on clothes or skin. It marks the transition zone between the external "dirty" side of the farm and the internal "clean" animal production area. While categorized as a medium-priority protocol for standard operations, it is considered critical on primary breeder farms.

Structured Facts

Classification

Physical Isolation / Visitor Management. Operational and structural biosecurity measure.

Purpose

Mitigates viruses carried on clothes or skin. Uses warm water and soap surfactants to emulsify lipid-enveloped viruses and wash away bacterial cells from human surfaces.

Standard Procedures

Transition space is divided into three distinct zones:

1. The Dirty Zone: Visitors/staff remove all street clothes, shoes, and personal items.
2. The Wet Shower Zone: A pass-through shower stall where personnel must wash with soap and shampoo.
3. The Clean Zone: Personnel put on farm-provided, laundered coveralls, undergarments, and disinfected boots.

Sanitation & Disinfection

Requires warm water and soap surfactants.

Entry & Exit Protocols

Must be paired with strict footwear color-coding and a Danish Entry bench to ensure decontaminated personnel do not step back onto dirty surfaces. Facility visitor log must be signed prior to entry.

Monitoring & Compliance

Auditors must verify that the transition space is clearly divided into three distinct zones, hot water systems are functioning properly, and the visitor log is signed prior to entry.

Advantages

Helps maintain the farm's health status and supports long-term biosecurity goals, specifically preventing total herd depopulation in high-value breeder operations.

Limitations

Depends directly on employee and visitor compliance.
