This document provides information about setting up a quality control laboratory for dairy operations. It discusses the types of dairy laboratories based on milk processing capacity and the necessary facilities like rooms for staff, instruments, bacteriology testing, balances, and sterilization. The location and layout of the lab should allow easy access, be away from noise and vibrations, and have at least two exits. General requirements for the lab include smooth walls, sufficient windows, adequate lighting, non-slip flooring, storage rooms, benches, sinks, cupboards, water supply, a distilled water plant, gas, ventilation, and fire extinguishers. The document also briefly outlines the accreditation process for analytical laboratories through NABL.
