Hepatitis E, Helicobacter pylori and peptic ulcers in workers exposed to sewage: A prospective cohort study
Workers exposed to sewage may have an increased risk of infection by Helicobacter pylori and hepatitis E virus (HEV). To assess the incidence of clinical hepatitis E and peptic ulcers and the seroconversion rate of antibodies to H. pylori and HEV in workers with and without sewage exposure, 332 workers exposed to sewage and a control group of 446 municipal manual workers entered a study with clinical examination and determination of antibodies to H. pylori and HEV. Findings are discussed. Overall, sewage does not appear to be a source of occupational infection by H. pylori or HEV in trained sewage workers with personal protective equipment working in a region with good sanitation infrastructure.

Working conditions and exposure to dust and bioaerosols in sisal processing factories in Tanzania
Information was collected on working conditions and personal exposures to dust, bacteria, and fungi in sisal fiber processing factories in Tanzania to identify health hazards and possible needs for preventive measures. Walkthrough surveys were performed in six sisal factories. Personal worker breathing zone dust samples were collected during sisal processing and analyzed for concentration of dust and for fungi and bacteria. It was found that workers were exposed to high levels of bioaerosols and most items considered to be a prerequisite for a good working environment were either missing or inadequate.

Measurement of airborne bacteria and endotoxin generated during dental cleaning
This study was conducted to characterize bioaerosol generation during dental treatments performed in standardized conditions. Dental cleaning procedures were performed in an isolated treatment room with a controlled ventilation rate. Aerosols concentrations before, during and 2hr after dental treatments were determined using samplers in the breathing zones of dental hygienists. Fluorescence microscopy in combination with culture showed that dental staff and patients were exposed to up to 1.86 E+05 bacteria/m3 generated during treatments. Fortunately, bioaerosols returned to baseline within 2h after the dental procedures.

Air diffusion in sorting rooms at domestic waste treatment centres - Which work station ventilation system?
Diffusion de l'air dans les salles tri des centres traitement des ordures ménagčres - Quelle ventilation au poste de travail ? [in French]
Domestic waste sorting may be the cause of respiratory or digestive diseases for employees in the waste treatment sector. Site measurements have led to the proposal of ventilation-based prevention methods for reducing biocontamination risk in manual sorting rooms. Each operator is positioned in a unidirectional fresh air flow. Ventilation system performance characteristics were evaluated by measuring dust concentrations, biological indicators and climatic parameters, providing an estimate of the personnel's thermal comfort. Findings are based on a design study involving two pre-sorting cabins before and after modifying the ventilation systems.

Monitoring microbiological flora in grease bacterial degradation fountains
Suivi de la flore microbiologique des fontaines de biodégradation des graisses [in French]
Grease bacterial degradation fountains consist of a tank containing a surfactant inoculated with a mixture of bacteria. Monitoring the microbiological flora of several fountains for one year allowed assessing the biological hazards. Bacteria quantification gave a concentration of 3.4 x105 CFU/mL. Microorganism identification revealed the presence of moulds and numerous bacterial species different from those initially seeded in the fountains. These microorganisms could originate from the working atmosphere or the personnel. A number of prevention measures are recommended, based on the potential risks of the identified germs and the type of exposure when using the tanks.

Exposure to dust and bioaerosols in poultry farming: Summary of observations and data
The poultry industry in the United Kingdom involves a range of activities including laying litter, populating with young birds, depopulating (reducing bird density during growth or removing at the end of the cycle), litter/manure removal, cleaning houses after depopulation, and routine maintenance and housework. The objective of this study was to measure workers' exposure to airborne dust and bioaerosols associated with these tasks in a representative cross-section of commercial poultry production. In total, eleven sampling visits to eight different farms were undertaken. The results showed that, at maximal exposure, poultry workers were exposed to total inhalable dust levels exceeding 10 mg/m3 during most activities. Exposure to airborne bacteria potentially exceeded one million cfu/m3 of air in each of the activities monitored. Maximal endotoxin levels ranged according to task from 30 to more than 38,000 EU/m3. Maximal airborne fungal concentrations ranged from 2,000 to 600,000 cfu/m3. Implications of these findings are discussed.

Sex ratio changes as sentinel health events of endocrine disruption
This review article on sex ratio changes as an early indicator of endocrine disruption presents the findings of recent epidemiological and mechanistic studies. The sex ratio in human populations can be readily measured to ascertain whether reproductive effects, such as subtle birth defects of the reproductive tract caused by exposures to chemicals, might be occurring. Male to female sex ratios appear to be declining in populations in several parts of the globe, possibly as a result of prenatal exposures to chemicals. Sex ratio data for communities with unusual occupational or environmental exposures can be compiled using traditional epidemiological techniques.

The occupational risk of Heliobacter pylori infection among workers in institutions for people with intellectual disability
This study evaluated Helicobacter pylori infection among 671 workers of two mental institutions for people with intellectual disability in Belgium. The study also included 439 administrative workers from other sites as a reference group. Data on socio-demographic characteristics, medical history and employment were collected by means of a questionnaire, and subjects underwent a serology test. The prevalence of H. pylori antibodies was 40.6% in the study group compared to 29.2% in the reference group. The crude odds ratio for occupational risk was 1.68. After adjusting for the various confounding factors, the odds ratio was even higher (1.98). In multiple logistic regression analysis, faecal contact was found to be an independent risk factor for H. pylori infection.

Professional photosensitive eczema of fishermen by contact with bryozoans: Disabling occupational dermatitis
Eczema associated with bryozoans is a form of occupational contact dermatitis caused by a living organism, occasionally associated with photosensitivity and essentially concerning fishermen. It can be extremely disabling and often giving rise to major social consequences since the eviction of the responsible allergen generally requires occupational reclassification, a measure which fishermen have great difficulty in accepting. Based on the description of three cases of photosensitive eczema associated with contact with the bryozoan Alcyonidium gelatinosum among fishermen from the English Channel coastline, this article describes the characteristics of this occupational dermatitis and its prevention.

Circulating lipopolysaccharides in the blood from "bioprotein" production workers
Workers producing bacterial single-cell protein (bioprotein) are exposed to organic dust containing high levels of endoxins (lipopolysaccharides, LPS). Workers in this industry have complained of episodes of fever, fatigue, chest tightness, skin dryness and rubor. The aim of this study was to quantify LPS and inflammatory mediators in plasma in eight non-smoking production and eight non-smoking, non-exposed controls. Airborne and plasma endotoxin concentrations were measured, as well as plasma high sensitivity C-reactive protein and different cytokines, chemokines and metalloproteinases. The workers who did not use personal respiratory protection were exposed to varying airborne levels of endotoxin (75-15,000 EU/m3). The level of plasma LPS was significantly elevated among the workers compared to the non-exposed controls. The workers also had increased levels of several inflammatory cytokines.

Cancer mortality risk among biology research workers in France: First results of two retrospective cohorts studies
The mortality of two cohorts of French biological research workers was compared with that of the French population. Standardized mortality ratio (SMRs) were significantly below 1.00 in both cohorts for all-cause mortality and for all-cancer mortality. There were some specific cancers for which the SMR was higher than 1.00, but not significantly. In one of the cohorts, a relationship was observed between ionizing radiation cumulative doses and all-cause as well as all-cancer SMRs. This needs to be confirmed with more precise assessment of exposures and additional information on individual risk factors.

An efficient analytical method for particle counting in evaluating airborne infectious isolation containment using fluorescent microspheres
The containment efficiency of patient isolation enclosures in hospitals must be verified to protect staff, other patients and visitors. This article reports on the development and validation of a simple technique to measure the low count concentrations of escaping airborne particles that might be present outside an isolation enclosure, based on micrometer-sized fluorescent polystyrene latex microspheres as a surrogate for pathogenic bioaerosols. Particles are released into the isolation enclosure and air is sampled inside and outside the room to capture airborne particles on 25mm diameter filters, which then allows the number of particles to be quantified using a random field counting approach. The method was found to be specific, sensitive and accurate.

About 320,000 workers worldwide die every year of communicable diseases, some 5,000 in the European Union. In the last decade, media coverage has raised public awareness of biological hazards, such as anthrax at work due to bioterrorist activities, severe acute respiratory syndrome (SARS) and the threat of avian flu. But biological agents are ubiquitous and, in many workplaces, workers face considerably harmful biological risks. The Community strategy 2002-06 called on the European Agency for Occupational Safety and Health to set up a risk observatory to anticipate new and emerging occupational safety and health risks. The expert forecast on emerging occupational safety and health biological risks was formulated from the results of three consecutive questionnaire-based surveys using the Delphi method. The full report has been analysed under CIS 08-214. This information note summarizes the contents and the findings of this forecast. It is also available in several other European languages.

Non-hospital based registered nurses and the risk of bloodborne pathogen exposure
The aim of this study was to assess the risk of exposure to blood and other body fluids among non-hospital based nurses employed in New York State. A self-administered questionnaire was completed by a random stratified sample of nurses. Results were reviewed to identify opportunities for improvement. Nine percent of respondents reported at least one needlestick injury in the 12-month period prior to the study. The percutaneous injury rate was 13.8 per 100 person years. Under-reporting was common; 49% of all percutaneous injuries were never formally reported and 70% never received any post-exposure care. Findings are comparable to data concerning hospital-based nurses. Underreporting is an important obstacle to infection prevention. Risk management strategies appeared to be poorly implemented. Other findings are discussed.

Microbial and endotoxin contamination of water-soluble metalworking fluids
The aim of this study was to evaluate the level of microbial contamination of metalworking fluids as a potential source of harmful biological agents in three metalworking plants in Poland. Ten samples of fluids, including four fresh fluids, were analyzed. The analysis showed total bacterial counts ranging from 1.0x101 to 3.2x107 CFU/mL, 60% to 100% of which were Gram-negative bacteria capable of producing endotoxins. The predominant species of bacteria was Shewanella putrefaciens present in 60% of the samples. As for moulds, the predominant species was Acremonium butyric. The average concentration of bacterial endotoxins was 773 EU/mL in used fluids and 285 EU/mL in fresh fluids. A correlation was found between endotoxin concentration and the number of Gram-negative bacteria detected in the fluids. Other findings are discussed.

Non-malignant disease mortality in meat workers: A model for studying the role of zoonotic transmissible agents in non-malignant chronic diseases in humans
A study of mortality from non-malignant causes was conducted between 1949 and 1989 in a cohort of 8520 meat workers in a union in Baltimore, Maryland, who worked in manufacturing plants where animals were killed or processed, and who had high exposures to infectious agents. Mortality in this cohort was compared with that in a control group of 6081 unexposed workers in the same union, and also with the United States general population. Proportional, standardized and relative mortality ratios were calculated. Significant excesses of mortality from septicaemia, subarachnoid haemorrhage, chronic nephritis, endocarditis and functional diseases of the heart were observed in meat workers when compared to the control group or to the United States general population. It is hypothesized that zoonotic transmissible agents may be responsible for the occurrence of some of the circulatory, neurological and other diseases observed among these workers.

Air quality in veal calf barns
Qualité de l'air dans les étables de veaux de lait [in French]
It is now recognized that the air quality in buildings used for animal production can affect the workers' quality of life and health as well as the productivity of the animals. Although this situation is well understood in the context of swine production, no study deals with veal calf breeding, which is expanding. The aim of this project was to characterize and quantify, by season, the chemical substances and biological agents present in the air of veal calf production buildings, to determine the risks to human health in relation to standards and guidelines, and to propose simple guidelines enabling facility managers to improve air quality, if needed. Results of the measurements show that there is no serious air quality issue in veal calf barns.

Biological hazards in occupational settings
Les risques biologiques en milieu professionnel [in French]
Protection against biological hazards within the enterprise remains hindered by several obstacles. Their effects being generally neither immediate nor spectacular, they are not considered as having the same priority as other more visible hazards. There is insufficient understanding of these hazards among persons responsible for occupational safety and health. This article presents a concise overview of these hazards and proposes an approach to safety and health based on the type of risk (infections, toxins, immuno-allergies, cancer) and the sector of activity (health care, agriculture, food industry, waste disposal).

Surveillance of occupational contamination by HIV, HCV and HBV among health care personnel
Surveillance des contaminations professionnelles par le VIH, le VHC et le VHB chez le personnel de santé [in French]
The surveillance of occupational seroconversions among health care personnel is in effect since 1991 for HIV (human immunodeficiency virus, or AIDS virus), since 1997 for HCV (or hepatitis C virus) and since 2005 for HBV (or hepatitis B virus). Between 1983 and 2005, 14 HIV seroconversions were notified. Within this surveillance programme, there were also 34 notifications of presumed HIV infections. With respect to HCV, 55 occupational seroconversions were counted between 1991 and 2005. In almost all cases, seroconversions were the result of a percutaneous skin injury. Close to half of the HIV and HCV seroconversions were related to accidents involving an exposure to blood when the putting away or disposal of equipment and therefore could have been avoided by following usual precautions. To this day, no occupational contaminations by HBV have been notified.

CIS 08-469 Guidance on preparing workplaces for an influenza pandemic
A worldwide influenza pandemic could have a major effect on the global economy, including travel, trade, tourism, food, consumption, investment and financial markets. Planning for pandemic influenza by business and industry is essential to minimize a pandemic's impact. The Occupational Safety and Health Administration (OSHA) therefore developed this pandemic influenza planning guidance based upon traditional infection control and industrial hygiene practices. Topics addressed: how a severe pandemic influenza could affect workplaces; how influenza can spread between people, classifying employee exposure to pandemic influenza at work, how to maintain operations during a pandemic, how organizations can protect their employees; steps every employer can take to reduce the risk of exposure to pandemic influenza in their workplace; what employees living abroad or who travel internationally for work should know.

Spread cheat
The Control of Substances Hazardous to Health Regulations (COSSH) 2002 of the United Kingdom (see CIS 03-1023) also covers biological agents, which include microorganisms, cell cultures or human endoparasites that can cause infection, allergy toxicity, or otherwise create a hazard to human health. Biological hazards are present in many workplaces, but particularly so in hospitals and the health-care sector. They can pose a significant threat to workers' health. This article outlines how these risks can be reduced, based on a suitable and sufficient risk assessment, coupled with effective infection control measures.
