In pharmaceutical quality management, the concept of “Quality Culture” has become indispensable. However, behind the birth of this concept lies a tragic accident that claimed many lives. This article reflects on the “5% Dextrose Solution” sterilization failure incident that occurred in the UK in 1972 and examines the importance of quality culture that emerged from this tragedy.
The Tragedy of 1972: The 5% Dextrose Solution Contamination Incident
In 1972, a major accident that would be etched in medical history occurred in the United Kingdom. Due to inadequate sterilization of 5% dextrose solution used in hospitals, five patients tragically lost their lives. This accident was not merely a manufacturing process failure but exposed fundamental problems in the quality management system of pharmaceutical manufacturing.
The cause of the accident was inadequate control in the sterilization process. Specifically, the primary factors were that the drain outlet of the autoclave (sterilization chamber) became blocked, resulting in bottles that did not reach sterilization temperature being shipped, and that quality inspection samples were taken from the upper layer where sterilization was sufficient, preventing the problem from being detected. This accident was widely reported in “The Daily Telegraph” newspaper of the time and caused a major shock to society.
Technical Analysis of the Incident
The incident revealed several critical failures in the sterilization process. The autoclave drainage system malfunction meant that condensate accumulated at the bottom of the sterilization chamber, creating a temperature gradient. While bottles in the upper portion of the load reached the required sterilization temperature of 121°C for the prescribed time, bottles in the lower portion were exposed to significantly lower temperatures due to the insulating effect of the accumulated water.
The sampling methodology compounded the problem. Quality control procedures at the time called for representative sampling, but the samples were consistently drawn from the upper layers of each sterilization batch. This systematic bias in sampling meant that the contaminated units in the lower portion of the autoclave load were never detected through routine quality control testing.
Microbiological testing of retained samples after the incident revealed contamination with Pseudomonas species and other gram-negative bacteria. These organisms had survived the inadequate sterilization process and proliferated in the glucose-rich solution, reaching levels that proved fatal when administered intravenously to vulnerable patients.
The Significance of the Clothier Report
Following this accident, an accident investigation report known as the “Clothier Report” was created. This report did not simply investigate the cause of the accident but became a catalyst for reconsidering the very nature of quality management in pharmaceutical manufacturing.
The report pointed out not only technical problems but also the importance of organizational culture and management systems. This became the origin that would later develop into the concept of “Quality Culture.”
Key Findings and Recommendations
The Clothier Report, officially titled “Report of the Committee Appointed to Inquire into the Circumstances, Including the Production, which led to the Use of Contaminated Infusion Fluids in the Devonport Section of Plymouth General Hospital,” was published in 1972 under the chairmanship of Sir Cecil Clothier. The report made several groundbreaking observations that would reshape pharmaceutical quality management.
The report identified multiple systemic failures:
Organizational Structure Deficiencies: The manufacturing facility lacked clear lines of responsibility and accountability. Quality control was treated as a separate function rather than being integrated into the production process. There was inadequate communication between production and quality control departments, creating silos that prevented effective problem identification and resolution.
Training and Competency Gaps: Staff members were inadequately trained in both the principles of sterilization and the critical nature of their work. The report emphasized that operators did not fully understand why certain procedures were important, leading to mechanical compliance rather than thoughtful execution of quality-critical activities.
Documentation and Record Keeping: The facility’s documentation practices were found to be insufficient. Critical parameters were not consistently recorded, and when records were kept, they were not systematically reviewed by qualified personnel. The lack of comprehensive batch records meant that when problems occurred, root cause analysis was extremely difficult.
Equipment Maintenance and Qualification: The autoclave that failed had not been properly maintained or qualified. Preventive maintenance programs were inadequate, and there was no systematic approach to equipment qualification and requalification. The blocked drain, which was the proximate cause of the sterilization failure, should have been detected through routine maintenance activities.
Management Oversight: Perhaps most significantly, the report identified failures in management oversight and governance. Senior management had not established appropriate quality metrics or key performance indicators. There was insufficient management review of quality data, and quality issues were not escalated appropriately through the organizational hierarchy.
The Clothier Report made several recommendations that would prove prophetic:
The establishment of clear quality responsibilities at all organizational levels, from senior management to production floor operators. The report emphasized that quality could not be delegated solely to a quality control department but must be the responsibility of everyone involved in pharmaceutical manufacturing.
The implementation of robust quality systems that would ensure consistent production of pharmaceutical products meeting their predetermined specifications. This included comprehensive documentation, systematic validation of processes and equipment, and regular review of quality metrics.
The development of what we would now recognize as a quality culture—an organizational environment where quality is genuinely valued, where problems can be raised without fear of reprisal, and where continuous improvement is actively pursued.
MHRA’s Perspective: The 2019 Viewpoint
The UK Medicines and Healthcare products Regulatory Agency (MHRA) has, as of 2019, applied the lessons learned from this historical accident to modern pharmaceutical management. MHRA positions Quality Culture not merely as a matter of regulatory compliance but as a value that should permeate the entire organization.
MHRA’s approach is internationally recognized as representative of European authorities’ pharmaceutical management philosophy. At its foundation lies the principle that quality is not created through inspection but built into the entire manufacturing process.
Evolution of Quality Culture Framework
Since the Clothier Report, MHRA has systematically developed and refined its approach to quality culture. In 2019, MHRA published significant guidance that explicitly addressed quality culture, building on decades of regulatory evolution and incorporating international best practices.
MHRA’s framework for quality culture encompasses several interconnected elements:
Leadership and Management Commitment: MHRA emphasizes that quality culture begins at the top of the organization. Senior management must demonstrate visible and sustained commitment to quality, not just through words but through actions and resource allocation. This includes establishing quality objectives that are aligned with business objectives, ensuring adequate resources for quality activities, and personally participating in quality reviews and investigations.
Risk Management and Quality Risk Management (QRM): Following the principles outlined in ICH Q9 (Quality Risk Management), MHRA expects companies to implement systematic approaches to identifying, assessing, and mitigating quality risks. This should be embedded in all aspects of pharmaceutical operations, from product development through commercial manufacturing and distribution. The risk-based approach should be documented and subject to periodic review.
Pharmaceutical Quality System (PQS): Building on ICH Q10 (Pharmaceutical Quality System), MHRA advocates for comprehensive quality systems that go beyond basic Good Manufacturing Practice (GMP) compliance. The PQS should include elements of quality planning, quality control, quality assurance, and continuous improvement. It should be scalable and adaptable to the organization’s size and complexity.
Data Integrity and Reliability: In the modern era, data integrity has emerged as a critical component of quality culture. MHRA has published extensive guidance on data integrity, emphasizing that reliable data is the foundation for quality decision-making. The principles of ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, plus Complete, Consistent, Enduring, and Available) must be embedded in organizational practices.
Transparency and Reporting: MHRA encourages open communication both within organizations and with regulatory authorities. This includes robust internal reporting systems for quality issues, near misses, and deviations, as well as timely reporting to MHRA of significant quality defects, recalls, and other safety-related issues.
Integration with International Standards
MHRA’s approach to quality culture is harmonized with international standards and guidelines, including:
ICH Q10 (Pharmaceutical Quality System): This guideline provides a framework for an effective pharmaceutical quality system that facilitates innovation and continual improvement while maintaining product quality. MHRA actively promotes implementation of ICH Q10 principles, which include management responsibility, management of resources, realization of products, and measurement, analysis, and improvement.
PIC/S Guidance on Quality Culture: The Pharmaceutical Inspection Co-operation Scheme (PIC/S), of which MHRA is a founding member, has developed guidance on quality culture that complements national regulatory expectations. MHRA’s inspectors are trained to assess quality culture during GMP inspections, looking for evidence of its presence or absence in organizational behaviors and practices.
ISO Standards: While not typically mandated for pharmaceutical manufacturing, MHRA recognizes the value of quality management standards such as ISO 9001 (Quality Management Systems) and ISO 13485 (Medical Devices – Quality Management Systems). These standards can provide structured frameworks for implementing quality culture, particularly for companies that manufacture both pharmaceuticals and medical devices.
The Importance of Quality Culture in Modern Times
Approximately 50 years have passed since the 1972 accident, and pharmaceutical manufacturing technology has advanced dramatically. However, the importance of quality culture remains unchanged and has, in fact, increased in significance.
Modern quality culture includes the following elements:
Universal Quality Consciousness: From management to frontline workers, all stakeholders must understand the importance of quality and put it into practice. This is not simply about following procedures but understanding the “why” behind quality requirements. Each individual must recognize their role in ensuring patient safety and product quality. Organizations must foster an environment where quality is valued as highly as productivity and where quality concerns can be raised without fear of negative consequences.
Continuous Improvement: Learning from past failures and constantly seeking better methods is essential. This includes systematic investigation of deviations and out-of-specification results, implementation of corrective and preventive actions (CAPA), and proactive identification of improvement opportunities. Organizations should establish metrics to track improvement over time and celebrate successes in quality enhancement.
Transparency and Communication: When problems occur, they should be shared openly rather than concealed, and the entire organization should examine solutions together. This requires psychological safety—an environment where individuals feel safe to speak up about concerns without fear of punishment or ridicule. Communication must flow not only upward from the shop floor to management but also downward and laterally across departments and functions.
Preventive Approach: Rather than responding after an accident occurs, risks should be identified in advance and preventive measures taken. This includes systematic risk assessment at all stages of the pharmaceutical lifecycle, from development through manufacturing and distribution. Organizations should implement robust change control procedures to ensure that changes do not inadvertently introduce new risks. Trending and analysis of quality metrics can help identify potential problems before they result in product defects or patient harm.
Additional Elements of Contemporary Quality Culture
Modern understanding of quality culture has expanded to include additional elements:
Knowledge Management: Effective management of organizational knowledge ensures that lessons learned are not lost when employees leave or retire. This includes comprehensive documentation, training programs that transfer both explicit and tacit knowledge, and systems for capturing and sharing best practices.
Cross-Functional Collaboration: Quality is not the sole responsibility of the Quality department. Modern quality culture requires effective collaboration across functions including Research & Development, Manufacturing, Quality, Regulatory Affairs, Supply Chain, and Commercial teams. Each function brings unique perspectives and expertise to quality decision-making.
Third-Party Management: In today’s global pharmaceutical supply chain, quality culture must extend beyond the walls of the manufacturer to include contract manufacturers, suppliers of raw materials and components, and service providers such as laboratories and warehouses. This requires robust supplier qualification programs, clear quality agreements, and ongoing oversight and audit of third parties.
Patient Focus: Ultimately, quality culture must be grounded in a genuine concern for patients. All quality decisions should be made with consideration of potential impact on patient safety and product efficacy. Some leading organizations include patient representatives in quality review boards and decision-making bodies to maintain this patient-centric perspective.
Ethical Culture: Quality culture is inseparable from ethical culture. Organizations must establish and maintain high ethical standards, including integrity in all dealings, honesty in reporting, and compliance not just with the letter but with the spirit of regulations. Senior leadership must model ethical behavior and make it clear that ethical lapses will not be tolerated, regardless of business pressure.
Lessons to Be Learned from History
As the blog title “Quality Culture: Learning from History” suggests, we can learn much from history. The 1972 accident was indeed a tragic event. However, the concept of quality culture that was born from this accident has greatly contributed to improving the safety of current pharmaceuticals.
Those involved in pharmaceutical manufacturing must never forget this history and must always practice quality management that puts patient safety first. Rather than relying solely on technological advancement, it is required to maintain and develop an attitude that values quality as an organizational culture.
The Continuing Relevance of Historical Lessons
The lessons from 1972 remain directly applicable to contemporary pharmaceutical manufacturing:
Complexity Does Not Eliminate Risk: Modern pharmaceutical manufacturing is far more sophisticated than it was in 1972, with advanced automation, real-time monitoring, and complex quality systems. However, this complexity can itself introduce new risks. Computer systems can fail, automation can malfunction, and the complexity of modern operations can make it difficult to identify when things go wrong. The fundamental lesson—that vigilance and attention to detail are always necessary—remains unchanged.
Culture Trumps Systems: The 1972 incident occurred not because procedures did not exist but because the culture did not support rigorous adherence to those procedures. Modern pharmaceutical companies may have comprehensive quality systems, detailed SOPs, and sophisticated technology, but if the underlying culture does not support quality, these systems will ultimately fail. People make decisions based on what they believe is important and valued, not on what is written in procedures.
Effective Communication is Critical: Many quality failures, including the 1972 incident, involve communication breakdowns. Information about potential problems existed but was not effectively communicated or acted upon. In modern organizations, with their complex structures, multiple sites, and global operations, effective communication is even more challenging but remains absolutely critical.
Oversight and Verification are Essential: The sampling methodology that failed to detect contamination in 1972 reminds us that oversight and verification procedures must be designed to be truly effective, not just to create an appearance of control. Modern organizations must regularly review and assess whether their oversight mechanisms are actually capable of detecting problems.
Case Studies: Learning from Recent Events
While 50 years have passed since the dextrose solution contamination, quality failures continue to occur in the pharmaceutical industry, reminding us that vigilance cannot be relaxed:
Fungal Meningitis Outbreak (2012-2013, USA): Contaminated sterilized methylprednisolone acetate injectable produced by a compounding pharmacy resulted in over 700 infections and 64 deaths. Investigation revealed numerous GMP violations, inadequate sterilization procedures, and a complete absence of quality culture. The facility continued to produce products despite visible contamination and repeatedly failed inspections. This case demonstrated that the lessons of 1972—proper sterilization, adequate quality control, and most importantly, a commitment to quality—had not been universally learned.
Heparin Contamination (2007-2008): Contamination of heparin with oversulfated chondroitin sulfate resulted in numerous serious adverse events and deaths. The root cause was deliberate adulteration of raw material, which was not detected due to inadequate supplier qualification and testing. This incident highlighted the importance of supply chain quality culture and the need for appropriate analytical methods to detect even sophisticated adulteration.
Various Product Recalls (Ongoing): Continuing recalls of pharmaceutical products due to quality issues—from contamination to out-of-specification results to data integrity problems—demonstrate that quality culture challenges persist. Regulatory warning letters from FDA, MHRA, and other authorities consistently identify cultural issues, such as inadequate investigation of problems, delays in implementing corrective actions, and failure of management to ensure quality system effectiveness.
These contemporary examples reinforce that the lessons from 1972 are not merely historical curiosities but remain urgently relevant today.
Current Regulatory Landscape and Quality Culture
The regulatory environment has evolved significantly since 1972, with quality culture now explicitly addressed in regulatory guidance and expectations:

Inspection Focus on Quality Culture
Modern GMP inspections by regulatory authorities increasingly focus on assessing quality culture. Inspectors are trained to look beyond documented procedures to evaluate whether quality culture truly exists within an organization. Evidence assessed includes:
Management Behaviors: Inspectors observe how senior management discusses quality, whether they are knowledgeable about quality issues, how they respond to quality problems, and whether resources are adequate for quality activities. Inspectors may interview senior executives to assess their understanding of and commitment to quality.
Investigation Quality: The thoroughness and objectivity of investigations into deviations, out-of-specification results, and quality incidents provide strong evidence of quality culture. Superficial investigations, delayed investigations, or investigations that appear to minimize problems suggest weak quality culture.
Data Integrity Practices: How data is generated, recorded, and used reveals much about quality culture. Evidence of data manipulation, incomplete records, or unreliable data systems indicates serious quality culture deficiencies.
Employee Engagement: Inspectors may interview employees at various levels to understand whether they feel empowered to raise quality concerns, whether they understand why procedures exist, and whether they believe management truly values quality. Employee turnover rates, particularly in quality roles, may also be examined.
Corrective Action Effectiveness: Whether corrective and preventive actions are effective and timely, and whether root causes are truly addressed rather than superficial symptoms, demonstrates the organization’s commitment to quality improvement.
Significant quality culture deficiencies can result in regulatory actions including warning letters, import alerts, consent decrees, and in extreme cases, criminal prosecution of responsible individuals.
Building and Sustaining Quality Culture
Creating a robust quality culture requires sustained effort and commitment:
Leadership Commitment
Quality culture begins with leadership. Senior executives must demonstrate genuine commitment to quality through their actions, decisions, and resource allocation. This includes:
Establishing Clear Quality Expectations: Leadership must articulate clear quality objectives and expectations and ensure these are understood throughout the organization. Quality metrics should be established and reviewed regularly at the highest organizational levels.
Providing Adequate Resources: Quality activities require resources—people, time, equipment, and funding. Leadership must ensure that quality functions are adequately resourced and that quality considerations are never compromised due to resource constraints.
Modeling Desired Behaviors: Leadership must model the behaviors they wish to see throughout the organization. This includes transparency in discussing problems, willingness to stop production when quality is questionable, and making difficult decisions that prioritize quality over short-term business considerations.
Accountability: Leadership must hold themselves and others accountable for quality outcomes. This includes consequences for quality failures but also recognition and rewards for quality excellence.
Organizational Structure and Governance
Quality culture is supported by appropriate organizational structures:
Quality Unit Authority: The quality unit must have sufficient authority and independence to fulfill its responsibilities. This includes authority to reject materials and products that do not meet specifications, to stop production when necessary, and to initiate and oversee investigations.
Cross-Functional Quality Governance: Quality oversight bodies, such as quality review boards or quality councils, should include representation from multiple functions to ensure diverse perspectives in quality decision-making.
Clear Roles and Responsibilities: All individuals should understand their quality responsibilities and how their work contributes to overall product quality and patient safety.
Training and Competency
Effective training programs are essential to quality culture:
Initial Training: New employees should receive comprehensive training not only on specific procedures but on the “why” behind quality requirements, including case studies of historical failures and their consequences.
Ongoing Training: Training should be continuous, including updates on new procedures, refresher training on critical operations, and training on quality culture concepts.
Competency Assessment: Organizations should assess whether training is effective through competency evaluations, not just completion of training sessions.
Quality Culture Integration: Quality culture concepts should be integrated into all training, not treated as a separate topic.
Communication Systems
Effective communication supports quality culture:
Open Communication Channels: Multiple channels should exist for employees to raise concerns, including direct supervisors, quality personnel, ethics hotlines, and senior management.
Non-Punitive Approach: Organizations should adopt a “just culture” approach that distinguishes between honest errors, at-risk behaviors, and reckless behaviors. Honest errors should not result in punishment but should trigger investigation and system improvement.
Information Sharing: Quality information should be shared broadly within the organization. This includes metrics, trends, investigation results, and lessons learned.
Upward Communication: Mechanisms must exist to ensure that information about quality problems reaches decision-makers who have authority to address them.
Continuous Improvement Mechanisms
Quality culture thrives in an environment of continuous improvement:
Systematic Review of Quality Metrics: Regular review of quality indicators, trends, and KPIs helps identify opportunities for improvement before problems escalate.
Effective CAPA System: Corrective and preventive action systems should identify root causes, implement effective corrections, and verify effectiveness of actions taken.
Management Review: Periodic management review of quality system effectiveness, as called for in ICH Q10, ensures that senior leadership remains engaged with quality performance.
Benchmarking and Best Practice Sharing: Organizations can learn from others through participation in industry associations, review of regulatory enforcement actions affecting other companies, and formal benchmarking activities.
The Role of Technology in Supporting Quality Culture
Modern technology offers powerful tools to support quality culture, though technology alone cannot create culture:
Quality Management Systems (QMS)
Electronic quality management systems can support quality culture by:
Facilitating Information Flow: Modern QMS platforms enable rapid communication of quality information across global organizations, ensuring that problems are quickly identified and addressed.
Providing Visibility: Dashboard and analytics capabilities give management real-time visibility into quality performance, enabling proactive intervention.
Ensuring Consistency: Standardized workflows and templates help ensure consistent approaches to quality activities across multiple sites and regions.
Creating Audit Trail: Complete electronic records provide transparency and accountability for quality decisions and actions.
However, organizations must be cautious that QMS implementation does not become merely a compliance exercise. The system should genuinely support quality decision-making rather than creating bureaucratic overhead.
Manufacturing Technology
Advanced manufacturing technologies can support quality:
Process Analytical Technology (PAT): Real-time monitoring of critical process parameters enables immediate detection and correction of process deviations, embodying the principle of building quality into the process.
Advanced Process Control: Automated control systems can maintain processes within tight specifications, reducing variability and risk of quality problems.
Digital Manufacturing Records: Electronic batch records eliminate transcription errors, provide complete audit trails, and enable rapid review and release of batches.
Data Analytics and Artificial Intelligence
Emerging technologies offer new capabilities:
Predictive Analytics: Analysis of historical data can identify patterns that predict future quality problems, enabling preventive action.
Deviation Analysis: AI-powered analysis of deviation data can identify common root causes across multiple events, supporting more effective corrective actions.
Risk Assessment: Advanced analytics can support more sophisticated risk assessment and prioritization of quality improvement efforts.
Important Caveats
While technology offers powerful capabilities, several cautions are necessary:
Technology Reflects Culture: A QMS or manufacturing system will reflect the culture of the organization implementing it. If the underlying culture is weak, the system will be poorly designed, poorly implemented, and poorly used.
Garbage In, Garbage Out: Data analytics and AI are only as good as the data they analyze. If data integrity is poor, analytic results will be misleading rather than helpful.
Human Judgment Remains Essential: Technology can support decision-making but cannot replace human judgment, particularly for complex quality decisions requiring consideration of multiple factors and stakeholder perspectives.
Validation and Reliability: Automated systems must be properly validated and maintained to ensure they function reliably. Over-reliance on technology without adequate oversight can create new risks.
Global Perspectives on Quality Culture
Quality culture is not solely a Western regulatory concern but has become a global imperative:
Emerging Markets
As pharmaceutical manufacturing has expanded globally, particularly to emerging markets in Asia, Latin America, and Eastern Europe, ensuring consistent quality culture across diverse geographies and cultures has become a significant challenge. Regulatory authorities in these regions, including:
China NMPA (National Medical Products Administration): Has implemented increasingly stringent GMP requirements and emphasized quality management system maturity.
India CDSCO (Central Drugs Standard Control Organisation): Following several high-profile quality failures affecting export markets, has strengthened domestic regulatory oversight and emphasized quality culture.
Brazil ANVISA (Agência Nacional de Vigilância Sanitária): Has adopted risk-based inspection approaches and emphasizes pharmaceutical quality systems aligned with ICH Q10.
These authorities recognize that quality culture is not culturally relative—the principles of management commitment, transparency, continuous improvement, and patient focus are universal, though their implementation may be adapted to local contexts.
International Harmonization Efforts
Organizations such as PIC/S (Pharmaceutical Inspection Co-operation Scheme) and the International Council for Harmonisation (ICH) work to harmonize quality expectations globally. This harmonization benefits both regulatory authorities and industry by:
Reducing Regulatory Burden: Companies can implement a single, globally acceptable quality system rather than maintaining multiple systems for different markets.
Improving Global Quality: Harmonized standards help raise quality standards in all regions, benefiting patients worldwide.
Facilitating Trade: Mutual recognition agreements based on equivalent quality standards enable more efficient international trade in pharmaceutical products.
Supply Chain Quality Culture
The global pharmaceutical supply chain presents unique quality culture challenges. Companies must ensure that quality culture extends to:
Contract Manufacturing Organizations (CMOs): Quality agreements and oversight must ensure that CMOs maintain quality standards equivalent to those of the contracting company.
Active Pharmaceutical Ingredient (API) Suppliers: API quality is fundamental to finished product quality, yet API manufacture often occurs in different countries from finished product manufacture, requiring robust supply chain quality management.
Excipient Suppliers: Though not typically subject to pharmaceutical GMP requirements, excipient quality is critical. Industry initiatives such as the International Pharmaceutical Excipients Council (IPEC) work to improve excipient quality standards.
Logistics and Distribution: Temperature excursions, counterfeiting, and contamination can occur during distribution. Quality culture must extend to logistics providers and distributors.
Conclusion
Quality culture is not something that can be built overnight. It is cultivated through daily work and permeates throughout the organization. It is our mission as those involved in the pharmaceutical industry to continue providing safer and more reliable pharmaceutical products by making use of the lessons learned from the 1972 accident.
Looking back at history is not merely for nostalgia about the past. It is an important learning process to make the future better.
The tragedy of 1972 reminds us that behind every pharmaceutical product lie the safety and lives of patients. Each tablet, each injection, each dose must be manufactured with care, attention, and an unwavering commitment to quality. This commitment cannot be achieved through procedures and inspections alone—it requires a quality culture where everyone, from the CEO to the newest production operator, understands their role in protecting patients and is empowered and motivated to fulfill that role.
As we face new challenges—increasingly complex products including biologics and cell and gene therapies, global supply chains, and rapid technological change—the lessons from 1972 remain our foundation. Patient safety must always come first. Problems must be addressed honestly and transparently. Continuous improvement must never cease. And above all, quality must be everyone’s responsibility, embedded in the culture of every pharmaceutical organization.
The victims of the 1972 dextrose solution contamination incident did not die in vain. Their tragedy sparked a revolution in how the pharmaceutical industry and regulatory authorities think about quality. By maintaining our commitment to quality culture and never forgetting the lessons of history, we honor their memory and protect future patients.
