Biosafety risk assessments are critical for cultivated meat production. They help identify and manage hazards that could endanger product safety, workers, or consumers. Unlike conventional meat, cultivated meat involves processes like cell culture and bioreactor operations, which come with unique risks.
Here’s a quick breakdown of the process:
- Identify hazards: Biological (e.g., bacteria, viruses), chemical (e.g., residues), and physical (e.g., foreign materials).
- Assess risks: Rank hazards by their likelihood and impact.
- Set control points: Define measurable safety limits for critical stages like cell harvesting and media preparation.
- Monitor continuously: Regular testing, equipment checks, and staff training.
The goal? Prevent contamination, maintain safety, and comply with strict UK and EU regulations. Tools like process mapping, HACCP frameworks, and verified suppliers (e.g., Cellbase) streamline hazard management while ensuring compliance.
Safety isn’t a one-time task - it requires constant monitoring and improvement. This guide lays out practical steps to help facilities stay safe and compliant.
Five P’s Approach for Biosafety Risk Assessment I Laboratory Biorisk Management
Step 1: Finding Hazards in Cultivated Meat Production
The first stage in assessing biosafety risks is identifying all possible hazards that could impact product safety, worker health, or consumer wellbeing. This involves a detailed examination of every production phase, from cell banking to final packaging. Skipping this step or approaching it casually can leave critical risks unnoticed, even with advanced control systems in place.
Process Mapping for Identifying Hazards
Creating a process map offers a clear visual guide to your production workflow, making it easier to pinpoint potential trouble spots. This involves diagramming each stage, decision, and material transfer in your facility. Each element on the map can reveal areas where contamination might occur.
Start by outlining the major production phases: cell isolation and banking, proliferation in bioreactors, differentiation into muscle and fat tissue, harvesting, and packaging. Then, break these down into subprocesses like equipment cleaning, media preparation, cell transfers, and quality testing. Even seemingly minor steps should be included to ensure no hazard is overlooked.
The HACCP (Hazard Analysis and Critical Control Points) framework is particularly useful for this process. A structured approach often uncovers risks that might be missed during less formal assessments.
Pay extra attention to points where materials move between environments or equipment. For instance, transferring cells from a seed bioreactor to a larger production vessel introduces multiple contamination risks, including exposure from equipment surfaces, transfer tubing, personnel handling, and the surrounding environment. A well-documented process map becomes a valuable tool for evaluating and prioritising these risks.
Categories of Potential Hazards
Cultivated meat production involves three main types of hazards, each requiring tailored strategies for identification and management.
Biological hazards are among the most pressing concerns. These include microbial contamination from bacteria like Salmonella and Listeria monocytogenes, viruses that could compromise cell lines, and prions introduced through animal-derived materials [1][2]. While cultivated meat avoids some traditional risks, such as faecal contamination, unique challenges arise within cell culture environments. For example, industry data shows that approximately 50% of cultivated meat companies have experienced contamination during cell harvest, often due to inadequate equipment sterilisation. Alarmingly, only 48% of facilities conduct routine microbial testing of their production areas [1].
Chemical hazards stem from the wide range of substances used in cell culture. Residues from growth media, antibiotics, recombinant proteins, and cleaning agents can pose risks to the final product [2][3]. Allergens from media components like soy or wheat also need consideration. Additionally, genetically modified cell lines may produce compounds requiring careful monitoring [2].
Physical hazards involve foreign materials that could contaminate the product during processing. Examples include fragments from equipment, particles from filtration systems, packaging materials, or fibres from clothing [3]. While these may seem less severe than biological or chemical risks, they can still cause serious harm to consumers and lead to regulatory issues.
Once hazards are identified, the next step is to evaluate their likelihood and potential impact. This lays the groundwork for managing risks effectively, especially within the supply chain.
Minimising Hazards Through Verified Procurement
Beyond internal processes, addressing supply chain risks is essential for maintaining biosafety. Every piece of equipment, growth medium, and processing material carries potential risks. Unverified suppliers can inadvertently introduce contaminated substances, incompatible chemicals, or subpar equipment into your production line.
Platforms like Cellbase tackle these challenges by offering a curated marketplace tailored to cultivated meat facilities. They connect production teams with verified suppliers of bioreactors, growth media, scaffolds, sensors, and cell lines that meet the specific demands of the cultivated meat industry. Each listing includes detailed compatibility specifications and quality certifications, reducing the likelihood of introducing unsuitable or contaminated materials.
Using verified procurement platforms eliminates many common hazards. Suppliers undergo strict quality checks to ensure their products meet food production standards, rather than just research-grade requirements. Comprehensive documentation and traceability make it easier to identify and address any contamination issues quickly.
For instance, when sourcing growth media, a general laboratory supplier might provide products with non-food-grade additives or undeclared allergens. In contrast, Cellbase ensures suppliers understand the stringent requirements of cultivated meat production. Similarly, equipment like bioreactors and sensors must be validated for food production purposes. Verified suppliers guarantee that these items are both food-safe and calibrated for the unique needs of cultivated meat manufacturing.
| Hazard Reduction Strategy | Traditional Procurement Risk | Verified Procurement Advantage |
|---|---|---|
| Supplier screening | Unknown quality standards | Pre-verified compliance with food production standards |
| Product compatibility | General lab specifications | Tailored to cultivated meat requirements |
| Traceability | Limited batch documentation | Full supply chain records |
| Technical support | Generic laboratory guidance | Expertise specific to cultivated meat |
Step 2: Assessing and Ranking Risks
Once hazards are identified, the next step is to evaluate their likelihood and potential impact. This helps prioritise the most pressing risks, ensuring resources are directed where they’re needed most.
Likelihood and Severity Assessment
To assess likelihood, consider factors like process frequency, sterilisation practices, staff protocols, and environmental controls. As noted earlier, improper equipment sterilisation and exposure during cell harvest are common sources of contamination. Addressing these requires detailed process mapping and thorough staff training to minimise risks[1].
Frequent sampling and multiple harvest points can increase the chances of contamination. A survey of 22 cultivated meat companies revealed that 13 identified process contamination - stemming from equipment handling, sampling, adding culture components, and harvesting - as the primary pathway for microbial risks[1].
Severity, on the other hand, measures the consequences of each hazard. For example, contamination with pathogens such as Listeria monocytogenes or Salmonella during cell harvest could lead to foodborne illnesses, costly product recalls, and damage to a company’s reputation. Factors like consumer health, production scale, operational disruption, and the vulnerability of end consumers all play a role in determining severity[1][3].
The harvesting and post-harvest stages are particularly critical. Both cultivated and conventional meat are generally sterile until this point, meaning any contamination during these phases can directly compromise the final product[1].
Environmental monitoring is a key tool here. Interestingly, only 48% of surveyed cultivated meat companies conduct routine microbial testing of their production environments, highlighting a gap in proactive risk management[1]. Keeping detailed records - such as logs of contamination events, microbial testing results, sterilisation processes, and environmental data - can help identify trends and emerging risks over time.
With both likelihood and severity assessed, the next step is to rank risks systematically using this data.
Risk Ranking Framework
A structured framework for ranking risks ensures consistency and helps justify decisions on where to allocate resources. This can involve either qualitative or quantitative approaches.
- Qualitative methods rely on risk matrices, which classify likelihood and severity into categories like low, medium, or high. These are useful for quick assessments and effective communication across teams.
- Quantitative methods assign numerical values to likelihood and severity. A common approach involves a 5×5 matrix, where likelihood ranges from 1 (rare) to 5 (almost certain), and severity ranges from 1 (negligible) to 5 (catastrophic). The risk score is calculated by multiplying these values. For instance, if microbial contamination during cell harvest is rated "likely" (4) and "major" (4), the resulting score of 16 highlights the need for immediate attention[2][4].
The HACCP (Hazard Analysis and Critical Control Points) methodology is a proven tool for identifying and managing critical risks. For example, in a theoretical analysis of a cultivated burger production process, HACCP identified improper equipment sterilisation and exposure during cell harvest as top risks. By implementing targeted measures like enhanced sterilisation protocols and staff training, contamination incidents were significantly reduced[1].
Risk rankings shouldn’t remain static. Regular reviews and updates based on new data or process changes are essential to keep priorities aligned with current conditions. This dynamic approach ensures continuous improvement and helps facilities stay ahead of potential risks.
Meeting UK and EU Regulatory Standards
In the UK and EU, risk assessments for novel foods like cultivated meat must be rooted in science and thoroughly documented. Regulatory bodies such as the Food Standards Agency (FSA) in the UK and the European Food Safety Authority (EFSA) require assessments to address biological, chemical, and physical hazards in detail[3][5].
Accurate risk ranking not only strengthens internal safety controls but also ensures compliance with stringent regulatory requirements. Comprehensive documentation is crucial - it should include the methodology, data sources, expert input, and the reasoning behind each risk ranking. This level of detail ensures assessments meet scientific standards and supports market approval.
Efforts are underway to harmonise risk assessment standards across the UK and EU, which is beneficial for facilities operating in multiple regions. However, local differences in implementation may still need to be accounted for[3][5].
Regular monitoring and updates are key to staying compliant. As scientific knowledge grows or production methods evolve, risk assessments must be revised to maintain safety and regulatory approval. Partnering with trusted suppliers through platforms like Cellbase can also support compliance, as these suppliers understand the specific demands of cultivated meat production and regulatory requirements.
Engaging with regulatory guidance, participating in industry training, and collaborating with expert networks are all effective ways for facilities to stay informed. These efforts not only help meet standards but can also reveal ways to improve risk management beyond the minimum requirements.

Step 3: Setting Up Critical Control Points and Limits
Now that risks have been prioritised, it’s time to pinpoint the exact stages in your production process where controls can effectively prevent, eliminate, or minimise biosafety hazards. These are known as critical control points, and they are the core of your facility's safety framework.
Identifying Critical Control Points
Critical control points are key moments in the cultivated meat production process where intervention can stop contamination in its tracks. Using the HACCP methodology, refine your process map by incorporating updated data on contamination risks to accurately identify these points[1][2].
One such point is media preparation. Raw materials entering your facility can introduce microbial contaminants even before cell growth begins. To mitigate this, it’s essential to closely monitor ingredient quality, storage conditions, and preparation methods to maintain sterility from the very beginning[1][2].
Another critical stage is bioreactor operation. Although bioreactors are designed to be sealed environments for cell growth, they are not immune to risks such as equipment failures, insufficient sterilisation, or external contamination. Just like in conventional meat production, sterility is critical until the bioreactor seal - or, in the case of traditional meat, the animal carcass - is breached[1].
The cell harvesting phase consistently poses the highest risk. Industry surveys reveal that improper sterilisation of equipment and exposure during harvesting are the most common sources of contamination, with six companies identifying these as their primary concerns[1]. This stage breaks the sterile barrier, exposing cells to personnel, equipment, and environmental factors.
Other potential control points include personnel interactions, equipment changeovers, and environmental conditions, all of which are common contamination vectors in cultivated meat production[1]. Pay particular attention to high-risk stages, such as cell harvest, where multiple contamination risks overlap, to determine which points to prioritise as critical control points.
These identified points will serve as the foundation for setting clear, measurable safety limits.
Defining Measurable Critical Limits
Once critical control points are mapped out, it’s essential to establish specific, measurable criteria that separate safe conditions from unsafe ones. These limits should be backed by scientific evidence to ensure both safety and compliance with regulations[2].
For example, during cell proliferation, bioreactor temperatures should be maintained at 37°C ± 0.5°C to prevent microbial growth[2]. Similarly, sterility standards are crucial. For final products, this might involve ensuring zero detectable Salmonella or Listeria monocytogenes, as outlined by UK Food Standards Agency guidelines[1][3]. These pathogen-specific criteria can be routinely verified through lab testing.
Another important factor is chemical residue thresholds, especially if growth media contain additives or processing aids. These residues must stay within safety limits, validated through precise testing protocols[2].
pH levels also play a significant role. Maintaining specific pH ranges during media preparation and cell culture not only supports cell growth but also creates an environment that discourages the growth of harmful microorganisms.
Avoid vague terms like "adequate sterilisation." Instead, use precise targets, such as ensuring equipment surfaces show zero colony-forming units per square centimetre after sterilisation. This clarity helps operators understand exactly what is required.
As your production scales up, regularly review and validate these limits. What works in small-scale production may need adjustments to remain effective at larger scales. Periodic evaluations are essential to keep your biosafety measures relevant.
Documenting Control Points and Limits
Turning critical control points into actionable safety measures requires meticulous documentation. Detailed records not only ensure compliance but also support trend analysis and continuous improvement[1][2].
Electronic logging systems are particularly effective for maintaining records. These systems can automatically timestamp entries, record measurements in metric units (aligned with UK and EU standards), and create tamper-proof logs suitable for audits[2]. Real-time data logging adds an extra layer of security by triggering immediate alerts when limits are breached.
Traceability is another must. Ensure records link each control point to specific production batches. This is crucial for investigating contamination issues or passing regulatory inspections[2]. Include measurements, calibration data, and environmental conditions for each batch.
When a critical limit is exceeded, detailed corrective action records are essential. Document what happened, why it occurred, the immediate response, and the steps taken to prevent future occurrences[1][2]. Organise records by production date, batch number, and control point to enable quick access during audits or investigations. Regular backups and controlled access further safeguard these records.
Staff training is just as vital. Everyone involved in monitoring critical control points should understand not only what to record but also how to do it correctly. Consistency across shifts and personnel changes is key to maintaining accurate documentation.
For equipment and systems, suppliers like Cellbase can connect you with monitoring tools and data logging systems that meet industry standards. Their verified listings ensure your systems align with regulatory requirements while maintaining robust monitoring capabilities.
Step 4: Monitoring, Response, and Improvement
Once critical control points are established and documented, the next step is to focus on monitoring these points, responding effectively to any issues, and refining your biosafety protocols over time.
Monitoring Procedures for Control Points
Monitoring is what turns your theoretical safety measures into actionable safeguards. It’s about catching deviations early - before they can compromise product safety.
Environmental monitoring is a cornerstone of this process. Yet, only 48% of companies conduct routine microbial testing, revealing a major gap in consistent surveillance practices[1]. This underscores an area where the sector can make significant strides. Regular swabs of production surfaces and equipment, especially in high-risk areas like harvesting and post-harvest handling, are essential. Harvesting, in particular, stands out as a critical stage, with 50% of survey participants identifying it as a primary source of microbiological contamination over the past year[1].
Equipment calibration and validation also need close attention. Improper sterilisation of equipment is one of the most commonly reported causes of microbial contamination[1]. To address this, ensure sterilisation processes consistently meet required parameters. Automated systems can help by continuously monitoring key variables like temperature, pressure, and time during bioreactor sterilisation.
In-process testing adds another layer of protection. Use techniques like PCR assays, PERT assays, and immune-based assays to detect adventitious agents such as viruses and pathogens[2]. Additionally, test cell culture media for residual substances or harmful by-products that could emerge during differentiation or maturation stages[2].
The frequency of monitoring should align with the risk level of each control point. For high-risk areas, weekly or bi-weekly environmental swabs are a good baseline, with more frequent checks during active production or after contamination events. For critical parameters like bioreactor sterilisation, continuous monitoring is ideal if feasible.
Tools like Cellbase can provide access to verified monitoring equipment and data logging systems that comply with UK and EU standards. These systems ensure the data you collect is reliable and actionable, forming the basis for timely corrective measures.
Corrective and Preventive Actions
When deviations occur, swift and strategic action is key to preventing small problems from escalating into bigger ones. Your response should focus on both immediate containment and long-term prevention.
Immediate corrective actions are about containment. For instance, if microbial contamination is detected during cell harvest, isolate the affected batch immediately, pause production, and investigate the equipment and personnel involved. Keep detailed records of the incident, including the time, affected control point, corrective steps taken, and the time required to resolve the issue.
Root cause analysis is essential for effective prevention. Survey data indicates that contamination is often linked to equipment issues, sampling errors, or procedural lapses during harvesting[1]. Identifying whether the root cause lies in equipment failure, procedural shortcomings, or human error will guide your preventive measures.
Engineering controls can help mitigate equipment-related risks. For example, if sterilisation issues are identified, consider upgrading sterilisation protocols, improving bioreactor designs, or modifying facility layouts to minimise cross-contamination risks[1]. These physical changes offer long-term solutions to recurring problems.
Administrative controls address risks related to personnel. This includes implementing stricter hygiene protocols and providing regular training to ensure staff follow best practices.
Using the HACCP framework ensures a structured approach to these corrective and preventive actions[1]. Document every step, including verification of effectiveness, to maintain compliance and support ongoing improvement.
Regular Reviews and Safety Culture
To keep your system effective and adaptable, regular reviews are essential. Biosafety isn’t just about technical systems - it also relies on fostering a workplace culture where every team member understands their role in maintaining safety and feels empowered to act on potential risks.
Systematic reviews and data-driven adjustments keep your risk management plan relevant. Conduct formal reviews whenever production processes change. Analyse monitoring data to spot trends and address recurring issues. Follow the same structured approach as your initial hazard assessment: review all stages of production, identify new or altered risks, evaluate current controls, and decide if updates are needed. Document these reviews thoroughly, noting the date, personnel involved, and any changes made.
Visualising data can help highlight trends and inform decision-making during regular management reviews. These meetings ensure resources are directed towards the most pressing risks.
Building a safety-focused culture requires leadership commitment and clear communication. Create reporting systems that encourage staff to flag potential hazards without fear of blame. Comprehensive training programmes covering aseptic techniques, equipment use, hygiene protocols, and deviation reporting are vital.
Tailor training to specific roles, ensuring production staff, quality assurance teams, and management receive relevant instruction. Follow initial training with regular refreshers and competency checks. Recognition programmes that reward safe practices and proactive hazard identification can further reinforce a strong safety culture.
Regular safety meetings, incident reviews, and open communication about corrective actions help embed safety as a shared responsibility across your organisation. Keep detailed records of training sessions, competency assessments, and safety communications - these not only support regulatory compliance but also demonstrate your commitment to maintaining high safety standards.
