The site documents and implements the methods, criteria and responsibilities for sampling, inspecting and testing inputs, part-processed product and finished goods, completed at the required intervals to agreed specifications and legal requirements, with sampling representative of the batch and confirming that process controls deliver the formulation and specification (2.4.4.1). Analyses use nationally recognised methods, company requirements or validated equivalents; internal laboratories testing inputs, environment or product follow the applicable ISO/IEC 17025 requirements including annual proficiency testing of analysts, and external laboratories hold ISO/IEC 17025 accreditation or an equivalent and are named in the contract service specifications (2.4.4.2). Laboratories located on site that do chemical or microbiological work that may pose a product safety risk are separated from food processing and handling, restricted to authorised people and signed as restricted areas (2.4.4.3); hazardous laboratory waste is isolated, contained and managed apart from food waste, with laboratory drains at least downstream of food area drains (2.4.4.4). Retention samples required by customers or regulation are stored under typical product conditions for the stated shelf life (2.4.4.5), and every inspection and analysis is recorded (2.4.4.6).
