Management guidelines for laboratory exposures to agents of bioterrorism
This article examines measures for preventing exposure to potential bioterrorism agents in biodefence research laboratories. Guidelines issued by the Special Immunizations Program at the US Army Medical Research Institute of Infectious Diseases (USAMRIID) are described. These include general safety measures and policies for vaccination and exposure evaluation. Results of evaluations of exposure to bacterial agents, viral agents and toxins are also analysed. It is concluded that a multifaceted policy of safety training, laboratory practices and procedures, personal protective measures, vaccination and early assessment of potential exposure with initiation of postexposure prophylaxis has been successful in minimizing the risk of disease in laboratory workers. Algorithms for evaluating and managing potential exposure are presented to provide guidance to other agencies.

Responding to the challenge of novel technology: An industrial hygiene and safety program for antibody production in maize
This article examines the challenges to occupational hygiene and safety posed by biotechnology, in particular the production of pharmaceutical proteins in plants. These challenges include: the widely varying potential for hazard depending on the activity of the protein and the nature and location of the target organ; limited data relating to industrial routes of exposure; and the inability to obtain relevant animal data because of high species-specificity. An approach to industrial hygiene and safety in this area is proposed based on the systematic assessment of employee risk using conservative assumptions and on the management of exposure. The method is described with reference to the production of monoclonal antibodies in maize.

Associations between acute symptoms and bioaerosol exposure during the collection of household waste
Associations between work-related symptoms and bioaerosol exposure were investigated in 22 household waste workers. Full-shift exposures to bacteria, fungal spores, endotoxins and total dust were measured. Data on symptoms experienced during work were obtained by means of a questionnaire. The median exposure levels of spherical bacteria and fungal spores were 0.4 and 0.1 x 106/m3, respectively, while exposures to rod-shaped bacteria, endotoxins and dust were low. The symptoms most often reported were unusual tiredness (24%), headache (22%), cough (15%), and irritation in eyes and nose (10 and 17%). The results suggest that acute work-related nose irritation is associated with exposure to bacteria. Exposure to rod-shaped bacteria is also associated with nose irritation and unusual tiredness. Finally, it is likely that cough is associated with fungal spores.

Blood and body fluid exposure risks among health care workers: Results of the Duke health and safety surveillance system
The objective of this research was to better define the blood and body fluids (BBF) exposure risk and risk factors among a cohort of health care workers. 24,425 health care workers were followed for BBF exposure events from 1998 to 2002. 2,730 BBF exposures were reported during the study period, corresponding to a total annual rate of 5.5 events per 100 full-time equivalents and a percutaneous exposure rate of 3.9. Higher rates were observed for males, persons employed less than four years, Hispanic employees, and persons less than 45 years of age. Even higher rates were observed for house staff, nurse anaesthetists, inpatient nurses, phlebotomists and operating room technicians. Rates of percutaneous exposures from hollow needles were found to decrease over the study period; however, exposure rates from suture needles appear to be increasing.

Occupational exposure to hazardous substances during plastics recycling
Stoffbelastungen bei der werkstofflichen Verwertung von Kunststoffen [in German]
Workers' exposure to hazardous substances and biological agents during the recycling of plastics was evaluated in twelve enterprises. Findings indicate that workers are mainly exposed to inhalable dust, with exposure levels in most cases being within occupational exposure limits for inhalable dust and heavy metals in this dust fraction. Exposure to respirable dust is low. Forklift trucks with diesel engines not equipped with particle filters and used in closed shops yield a significant exposure to diesel particulate matter. The concentration found was up to twice the short term exposure limit for diesel exhaust emissions. During the recycling of biologically-contaminated plastics, the mean exposure to endotoxins was found to be approximately 30 times higher than their normal ambient air concentration levels, with peak values of up to a factor of a thousand.

Legionella in occupational settings
Légionelles et milieu de travail [in French]
The bacteria responsible for legionellosis, Legionella pneumophila, was identified in 1997. Propagation of the disease in humans occurs through the inhalation of micro-droplets of contaminated water. Despite the lack of data on contamination in occupational settings, it is generally accepted that certain occupational groups are at risk of exposure. The prevention of hazards related to Legionella is based on the sound design of equipment, followed by appropriate management and maintenance. Occupational physicians and persons responsible for occupational hygiene in enterprises where equipment that may present a hazard is present frequently question the INRS on the means of prevention against Legionella and on the surveillance systems to be implemented. The objective of this review article is to present the current state of knowledge in this area and to describe the appropriate prevention measures.

Contamination of water in occupational settings
Contamination des eaux en milieu professionnel [in French]
Water has many different uses in the enterprise. Depending on the source of water, its chemical and bacteriological quality can vary. Microbiological hazards may be bacterial, viral or parasitical. They are characterized by their virulence, their toxicogenesis and their possible resistance to antibiotics. Depending on whether the chemical hazards are carcinogenic or non-carcinogenic, different approaches are used for defining the maximum admissible concentrations for exposed persons. Modes of occupational exposure include ingestion, inhalation of airborne humidity and contact, and involve a wide diversity of occupations including office workers (air conditioning systems), waste water treatment workers, miners and swimming lifeguards. Prevention is based on technical and sanitary measures to ensure that the water is of a good quality, the implementation of suitable technical procedures and epidemiological surveillance.

Air quality and respiratory health of workers in Quebec peat processing plants equipped with dust control systems
Santé respiratoire des travailleurs et qualité de l'air des tourbières du Québec possédant des systèmes de dépoussiérage [in French]
Although peat bogs are one of Quebec's important natural resources, few scientific data exist on these workplaces which employ approximately 700 workers. These workers are exposed to high concentrations of microorganisms that could affect their respiratory health. In this study, the biological contaminants contained in the peat moss and their effects on health are identified and the air quality in processing and packaging plants equipped with dust control systems is evaluated, together with the health status of the workers. The results show that the levels of exposure to various contaminants often exceed the permissible limits. For various reasons, the control systems at source do not maintain the dust emissions at acceptable levels. The report concludes with a series of recommendations to improve the working conditions in peat bogs.

Health care wastes that present infectious hazards - Waste disposal system
Déchets d'activités de soins à risque infectieux - La filière d'élimination [in French]
Health care wastes that present infectious hazards are an important public health issue. These potentially contaminated wastes are generated during medical or veterinary activities, and may expose persons handling or otherwise coming into contact with them to biological hazards such as HIV, HBV or HCV. Approximately 155,000 tons of these wastes are generated each year in France. Their disposal requires the involvement of specialized waste disposal enterprises, which apply strict traceability controls at each step. Precautions need to be taken starting from the time the wastes are generated. They need to be placed in suitable packaging according to the type of waste and the hazard it involves. Separation should be carried out at the source. Intermediate storage of these packages should be in containers placed in a suitable area that satisfies precise criteria. Waste collection should be carried out by persons specially trained with respect to biological hazards. Important precautionary measures should be taken during the incineration of these wastes. Empty containers should be washed and disinfected before being re-introduced into the collection cycle.

Blood exposure incidents: Importance of an early warning system
Accidents d'exposition au sang: intérêt d'un "système sentinelle" [in French]
This study highlights the importance of an early warning system for blood exposure incidents for determining case-by-case preventive actions when it is observed that a specific health care action presents a higher-than-expected frequency of incident occurrence (warning threshold). It presents the results of a database compilation of incidents having occurred in public hospitals in Lyon, France, between 1996 and 2003, together with their analysis. This analysis led to the evaluation and selection of safety equipment and enabled the introduction of specific and sustainable preventive and collaborative measures.

Determination of serum IgG antibodies to Bacillus anthracis protective antigen in environmental sampling workers using a fluorescent covalent microsphere immunoassay
To evaluate potential exposure to Bacillis anthracis (Ba) spores in 28 sampling and decontamination workers in the aftermath of an anthrax terror attack in October 2001, serum Ba anti-protective antigen (PA) specific IgG antibodies were determined using a newly developed fluorescent covalent microsphere immunoassay (FCMIA). Four serum samples gave positive anti-PA IgG results, from the pre-entry and follow up samples of two workers who had received their last dose of anthrax vaccine in 2000. It appears that the workers either had insufficient exposure to Ba spores to cause the production of anti-PA IgG antibodies or they were exposed to anthrax spores without producing antibody. The FCMIA appears to be a fast, sensitive, accurate and precise method for the measurement of anti-PA IgG antibodies.

Health effects associated with indoor storage of organic waste
This cross-sectional study examines health effects associated with the storage of organic waste at home for more than two days. 384 subjects completed a medical questionnaire on prevalence of airway, skin and general health complaints during the past year and home hygiene (storage of garbage, pet contact, indoor mould growth). With logistic regression analysis, odds ratios (OR) adjusted for sex, age, education level and frequent contact with pets were determined for indoor storage of waste for more than two days. Long indoor storage of organic waste was associated with skin rash (OR 2.05), itching skin rash for more than 2 month in the past 12 month (OR 3.58) or ever (OR 2.77) as well as lifetime diagnoses of skin diseases by a doctor (OR 3.16) or allergies other than hay fever (OR 2.74). Atopic subjects were higher at risk. These skin-related complaints and diseases probably result from microbial contamination, e.g. endotoxins due to waste.

Hazards, public health and decision processes
Risques, sécurité sanitaire et processus de décision [in French]
The evaluation of major public health hazards is a central aspect of national health-care planning. Decision processes represent a key step determining whether these hazards and risks justify or not the launching of public intervention programmes. Resulting decisions are nationwide in scope. These hazards or risks can be relevant to three areas: the health care system, food and the environment. This publication presents the results of a retrospective research project aimed at making it easier to understand sanitary safety decisions taken in response to hazards or risks. Eight cases are studied, which then form the basis of a comparative overview.

Biological agents
Les agents biologiques [in French]
Occupational exposure to biological agents may give rise to hazards in cases where these agents are pathogenic. Some workers are exposed to biological agents under controlled conditions, for example in biotechnology research laboratories or in the pharmaceutical industry, while others may be exposed without fully understanding the hazards, as may be the case in waste water treatment, solid waste disposal or health care settings. In either case, the evaluation and prevention of biological hazards require a proper understanding of these pathological biological agents and their hazards. This document describes the various types of biological agents (viruses, bacteria, fungi, protozoa and helminths), their form of life, their industrial relevance and their potential pathogenic effects.

Evaluation of hepatitis B serology among workers exposed to biological hazards
Valoración de serologías de hepatitis B en trabajadores con riesgo biológico [in Spanish]
The vaccination protocol in effect in Spain for workers exposed to hepatitis B virus calls for revaccination every five years. Since some recent studies suggest that the immunological memory may persist for at least twelve years, the serology of a group of 163 workers vaccinated since 1996-1997 was examined to establish their immunological state and to determine whether it would be possible to increase the revaccination intervals. Results indicated that more than 85% of the vaccinated workers still had protective antibody levels above 20UI/ml after five years and that it would be possible to extend the period between revaccination.

Follow-up study organized by the Association of Medical and Social Centres of the Ile-de-France region on accidents involving exposure to blood (IEBs): Analysis of the initial results
Observatoire ACMS des accidents avec exposition au sang (AES): mise en place des premiers résultats [in French]
Accidents involving exposure to blood (AEBs) have been regularly recorded and analysed for several years in large public hospitals in France. However, this has not always been the case in private health care institutions and in other sectors of activity that present a potential hazard. The objective of this study was to record and describe AEBs occurring in small-to-medium-sized institutions as well as in non-health-care settings in the Ile-de-France region. Between July 2001 and January 2003, 196 cases of AEBs were recorded, of which 15 occurred outside health care settings during waste collection, cleaning or supervision of the premises. In health care settings, the victims were predominantly women (90.4%), persons with less than two years of tenure (60.3%) and persons vaccinated against hepatitis B (95.7%). More than half the cases of AEB occurred during the disposal of contaminated material (58%), in particular because containers were often not easily accessible (40%). Gloves were not worn in 40% of AEB cases.

Surgical smoke: Are you aware of the risks?
Les fumées chirurgicales, connaissez-vous les risques? [in French]
The use of lasers in surgery is growing rapidly. However, when used on human tissues, these lasers vaporize cells and give rise to what is known as surgical smoke. The presence of viruses and bacteria in this smoke has been confirmed in several studies; furthermore, during the treatment of cancers using lasers, viable cancer cells were also detected. More than 80 chemicals have been found in surgical smoke, many of them harmful. Surgical smoke particles are respirable and can cause emphysema, bronchitis and pneumonia. The article describes a study on the decomposition products detected during laser treatment of pig skin, used for simulating human skin. Finally, the importance of proper ventilation and the use of masks are emphasised.

Occupational exposure to airborne fungi among rice mill workers with special reference to aflatoxin producing A. flavus strains
This study was undertaken to evaluate workers' exposure to mycoflora in rice mills in an Indian region. The airborne fungal communities were isolated and identified quantitatively. Of all the isolates, genus Aspergillus was predominant and among the Aspergillus species, A. flavus was the common isolate, irrespective of the method applied for sample collection. The number of isolates recovered from exposed workplaces was significantly greater than in control areas. The percentage of aflatoxin positive strains of A. flavus was 8%. Surface morphology of aflatoxin positive strains was studied by scanning electron microscopy. High concentrations of total and respirable dust concentrations were found in the exposed workplaces, whereas in the stores only the total dust concentration was significantly higher than in control areas. The study indicates that rice mill workers are occupationally exposed to airborne aflatoxin producing strains of A. flavus and should be equipped with protective masks.

Exposure to airborne Gram-negative bacteria, dust and endotoxin in paper factories
Air samples for determination of the concentration of Gram-negative bacteria, dust and endotoxin were collected at ten sites in two large pulp and paper mills in Poland. Plant "A" was an older facility while the plant "B" was a modern, fully automated factory with an effective ventilation system. The concentrations of Gram-negative bacteria in the air of examined factories were within a range of 11.0-310.0 cfu/m3, being the highest in plant A at the initial stages of the production cycle consisting of wood chip handling and pulp production. Although Gram-negative bacteria were present in the air of paper mills at relatively low concentrations which never exceeded the value of 1000 cfu/m3 proposed as a safe level, they may have adverse effects on exposed workers, as evidenced by high concentrations of airborne endotoxin and the presence of numerous potentially pathogenic species. Thus, these microorganisms pose a potential risk of respiratory disease for the workers of pulp and paper mills, in particular for those engaged in the handling of wood chips and pulp production.

Plasma C3d levels of young farmers correlate with respirable dust exposure levels during normal work in swine confinement buildings
Work in swine confinement buildings may lead to an inflammatory response and may be associated with increased levels of acute phase proteins. This study compared the inflammatory response of former farm workers who had previously developed respiratory symptoms of wheeze, cough, tightness of the chest during work in swine confinement buildings and had stopped work because of these symptoms, with that of age-matched former farm workers who were known not to have developed such symptoms. Both groups were subjected to an experimental exposure in a swine confinement building for three hours. Complement activation and acute phase proteins were measured in blood samples and broncho-alveolar lavage. Plasma C3d levels correlated significantly with respirable dust. There was complement activation in response to respirable dust, more so among cases than in the control group. It is concluded that acute occupational exposure to organic dust containing endotoxin leads to a weak systemic inflammatory response.

Borrelia burgdorferi infection among forestry workers - Assessed with an immunoenzymatic method (ELISA), PCR, and correlated with the clinical state of the patients
Borreliosis or Lyme disease is an infectious disease caused by the introduction of one of a class of spirochetes (the most common being Borrelia burgdorferi) into the blood stream. It is spread through the bite of the common European tick Ixodes ricinus. The most frequent occurrence is found among forestry workers and inhabitants of wooded areas. Diagnosis is based on immunoserologic tests. This study involved 52 forestry workers in Poland who responded to a questionnaire and were subjected to medical examinations. 61% were found to be seropositive. Possible correlations between the results of serological and polymerase chain reaction tests with the clinical state of the patients were investigated. Despite finding IgM antibodies in 10 persons tested, which would indicate recent infection, no DNA of B. burgdorferi was detected in their blood. Also, no DNA of this bacteria was present in 8 persons with IgM and IgG antibodies. The clinical data suggested past symptomatic infection, or even more often, asymptomatic infection with B. burgdorferi

Increased risk of hepatitis E in sewage workers from India
Considering faeco-oral transmission of hepatitis E virus (HEV), the risk of infection was assessed among sewage workers. The study involved 147 sewage workers and age-matched controls without exposure to sewage. IgG-anti-HEV positivity in enzyme-linked immunosorbent assay was significantly higher among sewage workers (56.5%) than among controls (19%). Furthermore, a significant rise in anti-HEV positivity was observed among sewage workers working for over five years. Multivariate regression analysis identified contact with sewage as the independent variable associated with anti-HEV positivity. Strict adherence to good working practices must take the top priority for the protection of these workers from sewage pathogens.

DREAM: A method for semi-quantitative dermal exposure assessment
This paper describes a new method of structured, semi-quantitative dermal exposure assessment for chemical or biological agents (DREAM). Two examples of dermal exposure of workers of a truck manufacturer show how the method allows a characterization of the tasks and provides insight into exposure mechanisms. It supplies estimates for exposure levels on the external clothing layer and on the skin, as well as for the distribution of dermal exposure over the body. Together with the ranking of tasks and persons, it provides information for sampling strategies and helps to determine who, where and what to measure. In addition to dermal exposure assessment, the systematic description of dermal exposure pathways helps to prioritize and determine most adequate measurement strategies and methods.

Evaluation of five extraction protocols for quantification of endotoxin in metalworking fluid aerosol
Occupational exposures to endotoxin-contaminated, water-based metalworking fluids (MWFs) are thought to contribute to cases of respiratory illness. The method most commonly used to quantify endotoxin is the Limulus amebocyte lysate (LAL) assay and this is the basis for the ASTM method E2144-01. In this study, multiple samples with similar mass and endotoxin loading were generated in order to compare four alternative extraction methods with the ASTM method. Aerosols with three concentrations of endotoxins (4.5, 350 and 1141EU/m3) were collected simultaneously on multiple filter samples using an exposure chamber system that provides a uniform distribution of MWF mist. It was found that the ASTM method yielded comparable estimations of MWF endotoxin aerosol concentrations but with higher variability than the four other extraction methods. In particular, extraction into pyrogen-free water at 25°C was more precise and simpler than the ASTM method.

Occupational exposure to metalworking fluid mist and sump fluid contaminants
This paper summarizes the analytical and occupational hygiene findings from a recent survey of occupational exposure to metalworking fluids (MWFs) in the metalworking industry in the United Kingdom. In general, occupational exposure to mineral oil MWF mist was controlled to under 3mg/m3 (8h time-weighted average) and to under 1mg/m3 for water-mix MWF mist. Fluid management was found to be poor, with most sites failing to meet industry good practice or Health and Safety Executive (HSE) standards. High levels of bacteria and endotoxins were found in sumps, and control of other factors, such as water-mix fluid concentration, was often poor. These findings will be used to develop guidance from the HSE on good practices, including indicative limits for MWF mist and sump fluid contaminants, with significant emphasis on sump fluid management (maintenance and monitoring), as well as control issues.

Review of occupational hazards from waste disposal in the health care sector
Revue sur les risques professionnels liés à l'élimination des déchets d'activité de soins [in French]
This literature survey reports on the current situation with respect to occupational hazards among workers involved in waste disposal in the health care sector. Biological hazards are the most important. In the early stages of waste disposal, blood exposure accidents are associated with the risk of infection with hepatitis or human immunodeficiency viruses. Other infectious diseases such as tuberculosis have been reported among workers involved in medical laboratory waste disposal. In health care establishments, chemical and radioactive wastes need to be managed by specialized and well-identified waste disposal systems. However, it appears that these systems are not always operational. Risks related to handling are important and are not always well controlled. Road transport risks have received little attention, but should not be overlooked given their potential seriousness.

Risk of blood exposure among hospital workers - Trends 1990-2000
Risque d'exposition au sang parmi le personnel hospitalier - Evolution 1990-2000 [in French]
A survey had been conducted among health care workers in 1990 to quantify the frequency and risk factors of blood exposure accidents (BEAs). 502 nurses from 17 hospitals had volunteered to participate. It was the first study that yielded data not only on the frequencies by nurse, but also by risk-involving task (injection, sample collection, installing and removing intravenous perfusions, work involving pacemakers). The most hazardous tasks were identified and ranked. The objective of the present study was to analyse the trends in BEA risks ten years later. Participants included 1506 volunteers among nurses in 36 hospitals. There were significant improvements from 1990 to 2000, the frequency of BEAs having decreased from approximately 0.35 to 0.12 per nurse per year, and needlestick injuries, which are the leading cause, from 0.26 to 0.07 respectively, per nurse per year.

Foodborne pathogens: The risk to the health of merchant seafarers
Patógenos en los alimentos: un riesgo para la salud de los marinos mercantes [in Spanish]
Foodborne illness is a global problem posing new risks to human health. Emerging pathogens, globalization of the food supply, changes in human behaviour, international travel, microbial adaptation and a breakdown of the pubic health system are factors which contribute to the threat of new and dangerous disease agents. Merchant seafarers, because of their unique occupational setting, may be particularly vulnerable to potentially debilitating foodborne illnesses. Factors like close living quarters, communal meal eating, contact with labourers in ports and access to potentially-contaminated food represent special hazards for these workers. These hazards are discussed in this article, together with the appropriate prevention measures.

Occupational and environmental exposure to bioaerosols from composts and potential health effects - A critical review of published data
The primary objective of this study was to critically review published literature related to airborne microorganisms or their constituent parts (bioaerosols) associated with organic waste composting facilities, and to establish whether there is a risk to worker health from the inhalation of these bioaerosols. The review aimed to identify the personnel at risk on compost sites, identify the circumstances, which increased the risk and indicate suitable control measures to limit the risk. A further aspect consisted of evaluating whether the airborne dispersal of bioaerosols from compost facilities could affect neighbouring facilities or residents, leading to health concerns. The review also looked at evidence of bioaerosol dissemination from sites, potential exposures and reported ill health.

Documenting the endotoxins that are present in the ambient air of textile plants handling cotton fibre in Quebec
Documentation des endotoxines présentes dans l'air ambiant des usines textiles du Québec traitant la fibre de coton [in French]
Approximately 13,000 textile industry workers in Quebec are exposed to cotton fibres. Now, it is known that the endotoxins contained in cotton can give rise to lung diseases. This report presents a research project aimed at examining the levels of these toxins at each of the various steps involved in cotton manufacturing, or as a function of raw cotton quality. Endotoxin concentrations in ambient air were determined at five textile plants using the chromogenic LAL (Limulus amoeabacyte lysate) method coupled with kinetic detection. It was thus possible to relate these concentrations to the processing steps and raw cotton quality, and to identify the conditions and techniques that needed modification to enable a better control of endotoxin concentrations at the workplace.

This article presents the results of a cross-sectional epidemiological study involving 26 hospitals in 10 autonomous regions. The aim of the survey was to determine whether laboratories where biological samples containing mycobacteria were handled complied with occupational safety and hygiene regulations, and if workers were sufficiently protected against risks from exposure to biological agents. Factors evaluated in the study included categories of workers, type of work, training in biological hazards and preventive measures. Findings show that laboratories do not fully comply with existing regulations and that the recommended preventive measures are not always followed.

The objective of this study was to establish the physical and chemical properties of soluble cutting fluids used in three metalworking enterprises in Quebec, and to evaluate their levels of microbial contamination. The respiratory health of the workers at one of the three enterprises was also determined. Novel analytical methods were employed, including colouring techniques involving fluorescent molecules as well as molecular biology techniques allowing the detection of specifically-targeted mycobacteria. High levels of bacterial contamination were found in these fluids. However, the majority of the strains identified are unlikely to account for the respiratory symptoms observed among the workers (allergic alveolitis).
