Core Responsibilities

Primary Functions

Conduct routine and specialized microbiological testing on raw materials, in‑process samples, finished products and environmental swabs, using methods such as aerobic plate counts, yeast/mold enumeration, pathogen detection and indicator organisms.
Design and implement microbiological testing programmes including incoming raw materials, finished goods, packaging and plant hygiene, to ensure food safety, shelf‑life stability and product quality compliance.
Develop, validate and optimise microbiological methods for food product development, preservation technologies, hurdle systems, natural antimicrobials and novel processing techniques to enhance microbiological safety and stability.
Perform environmental monitoring of food production facilities including surface swabs, air sampling, water testing, clean‑room monitoring and hygiene audits; analyse trends and initiate corrective actions.
Investigate deviations, non‑conformances, microbial spoilage events and foodborne illness or contamination incidents; perform root‑cause analysis, liaise with operations and QA, implement corrective & preventive actions (CAPA).
Collaborate with cross‑functional teams – R&D, production, supply chain, packaging, QA/QC and regulatory – to integrate microbiological risk assessments, process controls, product design changes and food safety strategies.
Maintain laboratory equipment and microbiology instrumentation (incubators, autoclaves, pipettes, plate‑readers, microbiological workstations), ensuring calibration, maintenance logs, performance monitoring and audit readiness.
Prepare and maintain accurate documentation including laboratory notebooks, electronic lab records (ELNs), SOPs, work instructions, test result logs, trend analysis and food safety reports in compliance with regulatory and accreditation standards.
Manage microbial culture collections, reagents, media preparation (agar plates, broth cultures), inventory control, expiry tracking and disposal of biohazardous materials in alignment with GMP/GHP/GMP standards.
Support product shelf‑life studies, stability testing and microbial challenge studies for new or reformulated food products; evaluate microbial viability, spoilage kinetics and shelf stability under various storage conditions.
Provide microbiological expertise to new product development teams: assess ingredient risk, evaluate process changes, ensure microbial safety and compatibility with shelf‑life, packaging and production requirements.
Train production, QA/QC and laboratory staff on hygiene practices, microbial control methods, GMP/GHP, sanitation protocols and microbiology fundamentals to strengthen food safety culture.
Stay updated with food safety regulations (FDA, FSSAI, EFSA), international standards (ISO 22000, SQF), microbial risk frameworks and emerging pathogens; ensure company policies are compliant and proactive.
Conduct microbiological risk assessments and hazard analyses (HACCP, preventive controls) to identify critical control points and define monitoring strategies, microbial limits and corrective action triggers.
Present microbiological findings, trends and risk assessments to management, quality teams or cross‑department stakeholders; prepare dashboards, visualisations and executive summaries.
Implement continuous improvement initiatives in microbiology lab operations, such as lean methodologies, 5S, automation of testing workflows, digital data capture and reduction of cycle times.
Ensure hygiene, sanitation and process controls are effective in food manufacturing environment: oversee sanitation programmes, verify microbiological effectiveness of cleaning and sanitisation, support production readiness.
Collaborate with external laboratories, third‑party testing services, accreditation bodies, and suppliers to coordinate sample testing, result validation, laboratory audits and ensure data integrity.
Evaluate packaging, process changes and shelf‑life extensions from a microbiological perspective; liaise with packaging and supply‑chain teams to implement controls and monitor microbial integrity over distribution.
Participate in cross‑site standardisation of microbiology labs, harmonise testing protocols, support multiple manufacturing sites or contract facilities, and ensure consistency of microbial testing, methodology and data across the organisation.

Secondary Functions

Support ad‑hoc microbiological data‑analysis requests, exploratory trend investigations or root‑cause studies to inform process or product improvements.
Contribute to the organisation’s microbiology strategy and roadmap: identify emerging food‑safety microbial technologies, new testing platforms or digitalisation opportunities and collaborate with product/engineering teams to translate these into action.
