The document provides information about auditing a microbiological laboratory. It defines quality audits and outlines the scope and objectives of auditing. Key areas that are audited include laboratory equipment, standard operating procedures, documentation, environmental monitoring, and testing processes. The document discusses auditing the laboratory facility, equipment, documentation systems, and testing methods to ensure compliance with standards.
This presentation describes outlines and discusses the regulations
applicable to the QA function and unit, structure, function and
application of the unit in the pharmaceutical manufacturing
environment. In addition, it discusses additional quality – related
responsibilities that may result when manufactures move toward a
quality system approach to quality that incorporates current quality
system models to further improve quality and harmonize with inter-
national quality requirements.
A vendor audit is a vehicle used by pharmaceutical companies, and other large companies as well, to inspect and evaluate a vendor’s quality management system, as well as its practices, products, and documentation.
The need to conduct vendor audits stems from a higher need for quality control in an industry that needs to be more regulated than any other industry in the world.
Reason why organizations use audits is to reduce cost and improve quality control
The objective of vendor audit is to develop an audit function comprising of qualified resources to effectively perform compliance audits to ensure that the contracts are being executed in accordance with the intent and address the net benefit to include cost recoveries, process improvement savings, fraud improvement and identification of hidden risks.
In order to reduce the cost pharmaceutical companies have increasingly become dependent on their supplier/ out sourcing partners for customer success. Though it has drastically reduced the production cost for companies, there is a heightened supplier risk and lack of visibility into supplier processes.
To gain an insight into supplier process and eliminate the risks, FDA encourages companies to conduct GMP supplier audit at the manufacturing premises of the supplier.
According to GMP code, it is sole responsibility of pharmaceutical industry to ensure that the suppliers manufacturing process, analytical tests and examinations are carried out reliably by the supplier and are in compliances with the applicable standards and regulations.
After the audit supplier must provide an appropriate corrective action plan with measures that that will be implemented by the supplier within a defined time frame to the manufacturer.
As the audit proceeds, there might arise some situations where the facts indicate there is a failure, either partially or wholly, of the quality management system, such a situation is called nonconformity/ deficiencies”.
Role of quality systems and audits in pharmaceutical manufacturing environmentMalay Pandya
By regulation, appropriate practice, and common sense, quality assurance (QA) is a critical function in the pharmaceutical manufacturing environment. The need for an independent unit to audit and comment on the appropriate application of standard operating procedures, master batch records, procedures approved in product applications, and the proper functioning of the quality control (QC) unit is paramount.
This helps assure that products are manufactured reliably, with adherence to approved specifications, and that current good manufacturing practices (cGMP) are maintained in conformance to regulation, both in the facility in general and the microenvironment of each product ’s manufacturing sequence.

It is process of “Establishing documentary evidence that provide a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes”.
In the pharmaceutical industry, it is very important that in addition to final testing and compliance of products, it is also assured that the process will consistently produce the expected results.
Validation is action of proving in accordance with the principles of good manufacturing practices, that any procedure, process, equipment, material, activity or system actually leads to expected results.
Cleaning validation is documented evidence with a high degree assurance that one can consistently clean a system or a piece of equipment to predetermined and acceptable limits.
The primary regulatory concern driving the need for cleaning validation is cross contamination of the desired drug substance either by other API from previous batch runs or by residues from the cleaning agents used.
The prime purpose of validating a cleaning process is to ensure compliance with federal and other standard regulations
1. Cross contamination with active ingredients
Contamination of one batch of product with significant levels of residual active ingredients from previous batch cannot be tolerated.
In addition to the obvious problems posed by subjecting consumers or patients to unintended contaminants, potential clinically significant synergistic interactions between pharmacologically active chemicals are a real concern.
2. Contamination with unintended materials or compounds
While inert ingredients used in drug products are generally recognized as safe for human consumption, the routine use, maintenance and cleaning of equipment's provide the potential contamination with such items as equipment parts, lubricants and chemical cleaning agents3. Microbiological contamination
Maintenance , cleaning and storage conditions may provide adventitious microorganisms with the opportunity to proliferate within the processing equipment.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

Annamalai University.
2. Definition of Audit
Quality audit is defined as a systematic and independent examination to determine whether activities
and related results comply with planned arrangements and whether these arrangements are
implemented effectively and are suitable to achieve objectives.
Scope and Objectives
To ensure quality of the Product
To assess effectiveness of QA system
It permits timely correction of problems
It established high degree of confidence
3. Audit schedule
• The most critical and failure-prone activities should be covered most frequently.
• Schedule can be structured to fit in around peak workload times throughout a year.
• Audit schedule can be simply documented as a matrix plan with audits set by month.
The auditing process,
Contact auditee
Prepare checklists and plan
Briefing
Actual audit – information gathering
Preparation of report
4. Action on findings
Follow up audit if required
Remember
Audits are of the system as a whole and not the person.
Prepare thoroughly for the audit
Use checklists
Checklist that is generic and covers standard issues.
Checklist that is tailored around the procedure to be audited.
Checklist that is as a result of a document review.
5. Gather sufficient evidence to substantiate the findings in the report.
Record the particular examples that were reviewed.
Have a look at work in action if possible – this can establish if there are inconsistencies
between actual procedure and work in practice.
Types of questions to use
What would you do if….?
I’m not quite sure what you mean by that. Could you perhaps explain it another way?
Is this always done this way?
Listen actively.
Be reassuring when necessary.
Bring the auditee back on track when necessary.
6. Always be clear of what you are hearing – if necessary ask for clarification.
Report writing
Remember to give praise where praise is due.
Make the findings constructive and definitive.
The findings must be based upon actual fact and evidence sighted during the audit.
Follow up on audits
• Corrective actions – designed to fix up the non conformance that has already occurred
Remember to get to the root cause of why the non conformance actually occurred.
• Preventive actions – to prevent non conformances occurring by taking appropriate action
where there could be potential for an issue to arise.
• Set realistic timeframes for addressing the findings.

8. Process for Audit
• A process audits an examination of results to determine whether the activities, resources and
behavior that cause them are being managed efficiently and effectively.
• A process audits not simply following a trail through a department from input to output, this is a
transaction audit.
How to Audit a Manufacturing Process ?
• An audit of a manufacturing process is a comprehensive examination of the process to verify that
it is performing as intended.
• Processes generate results, and process audits determine if the results are accurate and being
generated by an effectively managed process.
9. • Manufacturing process audits should ensure that procedures are properly followed, problems are
quickly corrected, there is consistency in the process, and there is continuous improvement and
corrective action as needed.
Reasons for conducting a manufacturing audit
• Assures procedures reflect actual practice (what we say is what we do)
• Uncovers inaccuracies so they can be quickly corrected
• Reveals the consistency of a process (from person to person, or day to day)
• Demonstrates a proactive approach to process improvement
• Encourages ongoing corrective action
10. A good manufacturing audit requires following actions
• Announcement in advance. Manufacturing audits are not meant to catch people doing
something wrong. On the contrary, during an audit you hope to catch people doing things right.
• A rating scheme to classify problems discovered. A rating scheme allows you to rank problems
in order to prioritize corrective actions.
• Trained auditors. Auditors should be familiar with both the area they are observing and with
auditing techniques.
• Planning and clear procedures. A manufacturing audit is more than just walking into a work area
and looking for trouble.
11. The steps listed below can help in planning and conducting an audit
• Select a process to be audited: Prioritize the processes that can be audited in terms of
importance and risk to the overall operation. Begin auditing the highest-risk areas first.
• Select a team to conduct the audit: The audit team should be familiar with the process being
audited. They should also be familiar with audit techniques such as sampling and analyzing
results. They must have the necessary expertise to identify problems and determine the
corrective actions needed.
• Decide how often the process should be observed (the frequency of the audit): If there are
significant problems or noncompliance, the process should be observed more often until the
situation is under control.
• Announce the audit in advance so there are no surprises: The objective is to improve the
process, which will require the cooperation of everyone involved
12. • Set up an audit schedule for the entire shift and follow the established audit schedule: The
number of observations will be your sample of the work for that shift. The audit schedule should
be determined in advance and should be as random as possible. Once established, the audit
schedule should be followed to provide results based on a random sample.
• Document any problems discovered and inform all those affected: The idea is not to assign
blame but to find a solution. The problems discovered become the basis for corrective actions and
follow-up. Everyone affected by the problem should be informed so they are aware and can
provide input to the resolution. Also, the process being audited will likely affect other processes
in the over-all operation.
• Determine and perform corrective actions: Let employees make suggestions for corrective
actions and select any that are appropriate, but management should make the final decision as to
which corrective actions to implement.
13. • Monitor corrective-action results: Perform follow-up monitoring to determine if the corrective
actions have actually eliminated the problem or if further action is required. Also verify that no
new problems have developed or entered into the process.
Product and Process Information
Process Audit
• A process audits an examination of results to determine whether the activities, resources and
behavior that cause them are being managed efficiently and effectively.
• A process audits not simply following a trail through a department from input to output -this is a
transaction audit.
14. • In contrast with rear-facing product inspections, process audits focus on how your team prepares,
produces, packages and distributes those products.
• This approach provides a more comprehensive view of the value stream than product audits,
which only sample the finished output.
Process audits look at details of manufacturing process such as,
• Fabrication steps
• Safety measures
• Temperature settings
• Pressure readings
• Calibration of gauges
15. Product Audit
• The product audits the assessment of the final product/service and its qualification for use
evaluated versus the intent of the purpose of the product/service.
• It ensures a thorough inspection of a final product before delivery to a supplier or a customer.
• Product audits take place after manufacturing is complete, but before the product reaches the
customer.
• If a product doesn’t meet standard requirements or specifications, the auditor documents the
findings and logs a non-conformance.
• While each company will have its own procedures for addressing non-conformances, the process
typically includes,
Identifying the problem
Containing the non-conformance
16. Reworking or repairing the products, if possible
Disposing of nonconforming products if you can’t rework or repair them
Determining the necessary countermeasures for preventing recurrence
• Product audits can help a manufacturer improve quality, profits, customer satisfaction, and
loyalty.
• An effective manufacturing process audit program that ensures the highest level of quality
requires both product and process audits. Though nearly all manufacturers conduct product
audits, fewer of them have defined process audit procedures in place
Quality goals for product audit
• Standardizing processes to ensure compliance with specific requirements such as time,
components, accuracy or temperature.
• Continuously reducing risk through systematic identification and correction of process errors.
17. • Monitoring key metrics for evaluating overall process performance.
• Assessing effectiveness of process controls such as procedures, instructions and specifications.
• Reviewing production resources, work standards and the manufacturing environment itself.
Difference between Process audit & Product audit
Process Audit Product Audit
Auditor will concentrate on process at each stage
& its relevant parameters process parameters like
temperature, pressure, speed etc.
Auditor will concentrate only on output of the
process & its relevant parameters.
18. SOP in Microbiology Laboratory
• SOPs and equipment manuals should be available for all instrumentation. If equipment
maintenance logbooks are used, they should be up-to-date with complete entries
andcontrolled.
• SOPs for laboratory equipment should include:
Maintenance frequency and maintenance activities
Calibration (if appropriate)
Cleaning, and operation
Method of cleaning/disinfection, cleaning agents, and frequency of cleaning
Operation of equipment including monitoring frequency and documentation
Emergency procedures in the case of a power outage or temperature deviation
19. Qualification of Equipment
• Critical instruments and equipment should be qualified and calibrated and included in a
routine calibration program.
• Equipment used to provide a controlled temperature should be set at the appropriate
temperature for its intended use. Qualification should include temperature mapping where
appropriate as for walk-in incubators and ovens.
• Autoclave load patterns should be established, assigned to cycles, and tested. Tests should
include heat penetration studies and biological challenge tests. If media is sterilized in house it
should take into account the heat sensitivity of some media and the risk of ‘over sterilising’ the
media. Autoclave re-qualification should occur periodically, according to established change
control procedures and with associated test protocols to verify that the autoclave has remained
in a validated state.
20. Stock cultures
• Microbial cultures are pure strains of one particular microorganism. Stock cultures are used
as inoculum for testing or reference samples. The cultures can be either isolated from an
environmental sample or purchased commercially as a pure strain.
• Microbial cultures may be kept almost indefinitely if care is taken during the transfer process.
Microbial cultures should only be transferred or “passed” five successive times if they will be
used as positive controls or in assays. The passages and dates of transfer should be
documented. Stability and maintenance of cultures should be documented.
• Once an agar slant containing a culture is removed from storage, it should not be used again.
• Storage conditions for cultures should be monitored and documented. Cultures may be frozen
onto sterile glass beads and stored at -20 C.
21. • They may also be stored under nitrogen in a mixture of glycerol, to prevent cell breakage upon
thawing.
• Cultures may also be lyophilized (freeze dried) and kept in a powder state. The laboratory
should have an SOP that includes storage conditions for microbial cultures used in the
laboratory.
• Microbial cultures and test plates with growth should be inactivated before being sent for
disposal.
• The procedures for inactivation should be in compliance with the site’s waste disposal policy
and procedure.
22. • The test then compares the level of microorganisms found in a control sample versus the test
sample over a period of 28 days.
• This testing is performed as part of a stability study. It is necessary to determine if a
preservative system will continue to be effective over the product’s shelf life and if the
preservative system is compatible with the formulation of the product. If a formulation changes
or a significant product or packaging change occurs, it is necessary to retest the effectiveness of
the preservative system.
Antimicrobial Effectiveness Test
• The Antimicrobial Effectiveness Test, a test described in the pharmacopoeias, demonstrates the
effectiveness of the preservative system in a product. A product is tested against a controlled
quantity of different types of microorganisms.
23. Growth Promotion Testing
• This test is performed to indicate that the selected test media is capable of supporting
microbial growth. Environmental isolates may be used in addition to indicator organisms to
test growth promotion. Organisms should be incubated at their optimum temperature so that
erratic results are not generated.
Identity Testing of Microorganisms
• Microbial organisms found through testing may need to be identified. The degree of
identification needed and when should be specified in an SOP.
• The site should have an approved SOP that contains the test method in use. Identification may
be performed through a series of testing with selected growth media or through a rapid
microbial identification system.
24. • Rapid microbial systems use electronic instruments designed specifically for microbial ID.
The equipment should be validated and there should be validated written procedures for
operation and maintenance.
• Cultures of known microorganisms should be used as positive controls to verify that the test is
working properly.
• There should be an SOP in place describing the test parameters and the operating conditions.
Environmental Monitoring
• This testing may include personnel, surface, water, air and other specialized testing. Agar test
samples from the air, personnel, and surfaces are incubated appropriately to grow both fungal
and bacterial contaminants. The temperature ranges used for incubation may be based upon
the relevant compendia, regulatory guidance or validated conditions.
25. • If growth appears, the laboratory should isolate the particular organisms, and characterize
them as appropriate. When to characterize and to what level should be described in SOP.
• All isolates and characterizations should be documented as to date, and type of sample.
Key Parameters in Auditing a Microbiological Laboratory
Prior to the audit
Find out which products are tested in the laboratory
Find out which methods/specifications should be used
Request a list of laboratory SOPs.
Request a list of laboratory equipment.
26. Request a list of laboratory deviations, out of specifications and/or out of trend
investigations from the previous 12 months.
Review previous audits to determine if there are pending actions.
During the audit
• Conduct a walkthrough of the laboratory.
Verify that there are designated areas for performing various testing functions.
Verify that the laboratory is maintained in a clean and orderly fashion.
Verify that the laboratory is in good repair, (i.e. no chipped paint on walls, no loose
ceiling tiles, etc.).
Verify that there is physical and dress discipline segregation from other laboratories.
27. Verify that personnel are following the dress code for the area.
Verify that all reagents and chemicals are labeled with expiration date and have not
expired.
Verify that equipment has been calibrated.

Managing a microbiological laboratory out of specification result.
Managing a laboratory spill.
Preparation and storage of stock solutions, reagents and culture media.
Verify that the laboratory has a system for collecting and maintaining data. If the system
is computer based, it must be validated and comply with applicable ERES requirements.
Review data and verify that the chosen product is tested as required.
29. • Ensure that the test method has been qualified for the product.
• Ensure that a procedure is followed for sampling and handling samples.
Verify that samples are labeled properly and uniquely identified.
Verify that there is a system in place that assures samples are stored under correct
conditions.
Verify that the sample is signed in using a well documented and established procedure.
Verify that there is a documented procedure for logging samples out of the lab.

• Moulds are most commonly encountered microbes on walls celling’s , particularly when poor
ventilation, temperature, and relative humidity control lead to high level of moisture.
Contamination may be excessive where damaged surfaces expose the underlying plaster.
31. • Surfaces should be smooth ,impervious and cleanable; damaged surfaces should be repaired
promptly.
Floors and drains
• Flours should be impervious to water, cleanable and resilient to day to day wear and tear.
• Flours should be laid flat to minimize the risk of excessive surface water(e.g. washing bays) or
ideally should slope towards drain.
• The auditor should pay particular attention to joints, seals and floor to wall coving to ensure
that surfaces should be repaired promptly.
• Where floor drainage channels are needed , they should be open shallow easy to clean drain
effectively.
32. • The auditor must be aware that any ‘static’ water can act as reservoirs for gram negative
organisms , particularly pseudomonas species.
Doors, windows and fittings
• These should be flush-fitting whenever possible. Wood readily absorbs moisture and can
generate high number of moulds; where present, it should be sealed with a high –glass paint
and any surface damage repaired immediately.
Equipment
• The ability of bacteria to attach to surfaces such as stainless steel and plastic and survive
should not be under estimate.
• Every piece of equipment has its own particular nooks and crannies where microbiological
contamination can reside; internal threads and dead legs cause particular problem.
33. Cleaning of equipment
• Cleaned equipment can be readily decontaminated before use.
• The auditor should review the quality water used in final rinsing stage and how equipment is
dried and stored to minimize the risk of contamination by pseudomonas and other gram-
negative bacteria .
Pipelines
• Pipeline must be completely drainable to ensure that trapped fluid does not provide a
hospitable environment for growth of bacteria.
• Internal surfaces should be smooth and polished to minimize pits where microbes may lodge.
• Joints and welds should be kept a minimum, since they may provide a protective haven for a
microorganism. Its sealed with lagging material.
34. Raw materials
• Raw materials pose a major contamination threat to the product and the production
environment, and warrant special attention from auditor.
• Untreated raw material of natural origin contain an extensive and varied microbial
population, including potentially pathogenic organisms, such as E.coli and salmonella
species.
• In case of excessively high bioburden, pre-treatment may be needed to reduce the bioburden
to an acceptable level, using process such as heat filtration, irradiation, recrystallization from
a biocidal solvent or where compatible ethylene oxide gas.
• Irrespective of the type raw material used, the auditor should confirm that the material is
provided by an ‘approved ‘supplier.
35. • Confidence in the suppliers manufacturing process and their quality system, which have been
challenged through audit. likewise the sampling programmer used should be satisfactory
based upon the nature of the raw material (natural/synthetic), the history and performance of
the supplier, and end use of raw material.
• Sampling procedure should be reviewed.
• Reduce the risk of contamination both sample and bulk.
• Sampling equipment should be dedicated and clean. Samples should be properly trained in
aseptic techniques.
• Warehouse storage condition should also be reviewed; temperature control should be
satisfactory; pest control should be effective; and containers should be positioned so that they
do not come into contact with damp; cold surfaces such as walls and floors.
36. Water
• Water is principle of raw material used in pharmaceutical industry. When reviewing water
systems usually as part of a ‘product based audit', the auditor must establish quickly an
understanding of the system and how it performs.
• Key facts to know include whether water is used directly manufacture ,and what's grades of
water used.
• Management and operational issues include who owns the system, its complexity (one or
multiple plants).
• A schematic of the system should be provided.
37. Packaging materials
• Cardboard, paperboard and pulpboard, unless sealed or treated, can provide a rich source of
contamination, particularly moulds and gram positive bacteria, often as resistant spores.
• Materials become moist through poor storage ,levels of microbiological contamination can
increase significantly.
• Material such as glass, synthetic rubbers, plastics and laminates have minimal surface
microbial counts.
• However, if stored with limited protection in dusty or damp conditions and packed for
transportation in cardboard boxes, often on damp ,dirty wooden pallets, they may contain
moulds and bacterial spores.
38. Effective ventilation
• The aerial route of contamination is common and can be significantly reduced by an effective
heating ventilation and air conditioning system.
• Humidity and Temperature control is important , since this not only provides a pleasant
working environment, but also reduces the risk of mould contamination.
Cleaning and disinfection
• Although routine sanitization of surfaces is key to controlling environmental contamination,
its importance is often over looked. The sanitization programme and procedure should be
reviewed to confirm the frequency and precise method of cleaning and their scientific basis.
39. • The cleaning records should confirm procedural compliance (when, where, and by whom).
• The activity of any disinfectant used should be appropriate for the wide range of
environmental contaminants likely to be present .
• The manufacturers instructions should be followed and fresh disinfectant solutions should be
made up before use.
• Mops, sponges and cloths can provide an ideal environment for rapid and extensive growth of
water-born organisms such as pseudomonas species.
• Inadequately stored and maintained cleaning equipment can be highly efficient vehicles for
spreading micro-organisms throughout the environment.
