1. PURPOSE AND SCOPE

The purpose of this Standard Operating Procedure (SOP) is to establish uniform protocols for the sanitary and efficient production, collection, and storage of industrial-grade milk. This SOP applies to all personnel, equipment, and livestock facilities managed by [___________] (hereinafter referred to as the "Company").

2. PRE-MILKING SANITATION PROTOCOL

Before the commencement of milking, the following steps must be verified by the Shift Supervisor:

• Equipment Sanitization: All milking clusters, pipelines, and receiving vessels must be flushed with an approved chemical sanitizing solution at a concentration of [___________] ppm.
• Personnel Hygiene: All operators must don sanitized gloves, protective aprons, and hairnets. Hand washing must be performed for no less than [___________] seconds using approved antimicrobial soap.
• Udder Preparation: Each animal must be visually inspected. Teats must be cleaned with a single-use towel and a pre-dipping solution of [___________] (active ingredient).

3. MILKING OPERATIONS

• Milking Sequence: Animals shall be milked in the order of [___________].
• Flow Monitoring: Milk flow rates must be monitored to ensure complete let-down. Vacuum pressure must be maintained at [___________] kPa throughout the process.
• Contamination Control: If milk becomes visibly contaminated, it must be diverted immediately to the waste line identified as [___________].

4. POST-MILKING AND COOLING

• Post-Dipping: All teats must be treated with a post-milking teat dip containing [___________] to seal the teat canal.
• Immediate Cooling: Milk must be transferred through a plate heat exchanger to reduce temperature to [___________]°C within [___________] minutes of extraction.
• Storage Parameters: Milk must be held in stainless steel bulk tanks at a temperature between 2°C and 4°C.

5. QUALITY CONTROL AND TESTING

The Quality Assurance Officer shall conduct the following tests on each batch collected:

1. Somatic Cell Count (SCC): Target threshold: [___________] cells/mL.
2. Bacterial Count (APC): Target threshold: [___________] CFU/mL.
3. Antibiotic Residue: Every bulk tank load must be tested for inhibitory substances using [___________] methodology prior to shipment.

6. EQUIPMENT MAINTENANCE AND CALIBRATION

• Daily Maintenance: Vacuum pumps and pulsators must be inspected daily.
• Monthly Calibration: All temperature sensors and flow meters must be calibrated against certified reference standards by [___________] (Department/Individual). Calibration records must be maintained in File ID: [___________].

7. NON-COMPLIANCE AND CORRECTIVE ACTIONS

In the event of a deviation from these standards (e.g., cooling failure, contamination event), the following actions are mandatory:

• Isolation: The affected batch must be isolated and tagged as [___________].
• Reporting: A Formal Incident Report must be filed within [___________] hours to the Plant Manager.
• Remediation: Equipment must be cleaned and re-sanitized using protocol [___________] before operations resume.
