Occupational exposure to Mycobacterium bovis infection in deer and elk in Ontario
In late 1991, two herds of deer and elk were depopulated at a slaughtering plant in Ontario, Canada, followed by processing of infected animals at a rendering plant. A questionnaire plus tuberculin skin-test survey was conducted of 104 exposed slaughtering and rendering plant workers, and government veterinarians and inspectors. Overall, 17 cases were skin-test positive; one of 51 initially skin-test negative subjects tested a second time three months later became positive, consistent with the risk associated with occupational exposure during the depopulation of tuberculous elk previously observed in Alberta, Canada. The likely route of transmission is through aerosols. Possible reasons for the low conversion rate include the use of respiratory protection, absence of a tanning plant, an enclosed rendering plant process, and late skin testing which may have underestimated the number of conversions. Recommendations for prevention are summarized.

The incidence of tuberculosis among North Carolina migrant farmworkers, 1991
All locatable subjects (n=94) for whom tuberculosis prevalence had been determined in an earlier study were tested with purified protein derivative (PPD) and control antigens, sputum sampling and chest x-rays. Of the 46 who had been tuberculin negative (confirmed with control antigens) three years earlier, two had developed active tuberculosis in the interim and 14 (30%) were tuberculin positive. All had been engaged continuously in migrant farmwork. Lack of access to health care, an institutional feature of migrant farmwork, was significantly associated with primary infection.

Evaluation of the health risks to compost workers due to emission of microbes and development of protective measures
Abschätzung von Gesundheitsrisiken für Müllwerker durch Keimemissionen und Entwicklung von Arbeitsschutzmassnahmen [in German]
The total and suspended particulate matter of 4 different composting plants was analyzed to determine the presence of pathogenic microorganisms. Total values of pathogens ranged between 100 and 100,000cfu/m3. Viruses were detected in 49 of 165 samples. In all composting plants mesophilic and thermophilic actinomycetes were found in numbers above 100,000cfu/m3. Moulds mostly amounted to more than 10,000cfu/m3 with peaks of 1,000,000cfu/m3. Tests of sensitization to actinomycetes and moulds in 30 workers from the composting plants showed significantly higher antibody titres against actinomycetes than in a control group. There were no signs of illness in the workers. Health protection of workers can be achieved through blood monitoring for antibodies, enclosing conveyor belts, exhaust ventilation, confining the use of work clothing to the composting plant and prohibition of any food intake in the workplace. Summary in English.

Investigation of the health risk involved in cleaning work
Untersuchung tätigkeitsspezifischer Gesundheitsrisiken im Reinigungsgewerbe [in German]
Statistical data on the types of accidents and occupational diseases among cleaning personnel were evaluated to determine the accident and health risks of this trade. In addition, data from periodic medical examinations by industrial physicians and a questionnaire survey of 645 cleaners were used. All cleaners, including bottle washers and metal cleaners, were included in the study. The most frequent causes of accidents were slipping, falls on the level and among glass and window cleaners falls from heights. Among occupational diseases skin diseases, mainly skin allergies and eczema, were most frequent. Infectious diseases, mostly hepatitis B, ranked second in frequency.

Risk of viral hepatitis C infection among medical personnel
Hasikun lahadbaqa bedaleqet kaved negifit C (HVC) beqerev haosqim berefua [in Hebrew]
A review. The risk of HCV infection among medical personnel and the consequences of such infection seem to be less severe than for HBV infection. In Israel, at least 0.5% of the sick population carry the hepatitis C virus in their blood; the development of a kit for the identification of HCV in blood makes it easier to identify such carriers.

Occupational irritant contact dermatitis and fungal infection in construction workers
A study was made of six construction workers who developed chronic skin diseases on their hands over a period of 15 years. Four developed Trichophyton rubrum infection, and the other two an irritant contact dermatitis. All of them carried out jobs which caused traumatization of the skin due to the presence of ethylene glycol and mineral oils during operation of pneumatic hammers in winter. Construction workers may be at risk of developing an occupational skin disease involving fungal infection.

Workplace infections with HIV virus in France as of 31 December 1993
Infections professionnelles par le VIH en France - Le point au 31 décembre 1993 [in French]
Since 1984, 65 cases of proven seroconversion (117 presumed contaminations) following occupational exposure have been reported by health care professionals in industrialized countries. In the USA, the Centers for Disease Control and Prevention (CDC) have recognized 39 cases of seroconversion among health care personnel following occupational exposure; in Europe (outside France), 14 cases have been reported; in France 8 proven seroconversions (and 20 presumed contaminations) have been reported. In prospective studies, the assessed risk reaches an average of 0.37% (0.21%-0.54% ) following percutaneous exposure. In these cohort studies, only one case of seroconversion has been reported following splashes on wounded skin or mucosa (average risk 0.01%-0.25%). Other workers outside the medical or paramedical profession could be occupationally exposed to HIV.

Modeling respirator penetration values with the Beta distribution: An application to occupational tuberculosis transmission
Even workers wearing respirators may be infected following inhalation of respirable particles, termed droplet nuclei, that carry viable mycobacterium tuberculosis bacilli. Based on the expected number of infectious doses inhaled, the Poisson probability model is used traditionally to predict an individual's risk of infection. This article synthesizes the beta distribution, as applied to average penetration values among a respirator-wearing population, and the Poisson distribution, as applied to an individual's infection risk, to describe the population risk of Mycobacterium tuberculosis infection.

A profile of sandstone mine workers of Jodhpur and dust borne diseases
A questionnaire survey was carried out among 264 silica-exposed sandstone mine workers in Jodhpur, India. 189 workers (71.6%) complained of respiratory problems; some were either under treatment for tuberculosis or were suffering from perennial cough syndrome. Radiological examinations of 82 workers revealed that a large number were suffering from silicosis, silico-tuberculosis and tuberculosis. Accidents were also frequent as most of the work was carried manually using primitive tools. The report also covers working conditions and the lack of occupational health schemes and compensation for occupational diseases.

Cryptosporidiosis. Hidden in name and nature
The nature of the human diarrhoeal disease cryptosporidiosis is explained along with the need for health education among workers. Cryptosporidiosis is caused by ingestion of oocysts of a protozoan Cryptosporidium parvum; the parasite is predominantly waterborne, but may also be transmitted from animals and other people. Since no effective vaccine is yet available and oocysts are resistant to traditional methods of water sanitation and to many disinfectants, all workers in environments subject to faecal pollution (workers in close contact with animals, water sanitation personnel) should be advised of the risks.

Warts in butchers - A cause for concern?
Warts caused by human papillomavirus (HPV) are common on the hands of workers in the meat industry; one particular viral type, HPV7, predominates. Studies have found no relation between the excess prevalence of warts among these workers and a number of factors and it was concluded that some constituent of meat may enhance the effect of HPV7. Other studies have indicated a relation between butchers' warts and an apparent increase in the occurrence of lung cancer found in those who handle fresh rather than chilled meat. Further clarification of these studies is required.

Results of a rubella screening program for hospital employees - A five-year review (1986-1990)
A US hospital employee health service rubella screening programme was evaluated over a five-year period from 1986-1990. A total of 6,115 new employees were screened for evidence of rubella immunity. Rubella serology was performed on 5,893 (96.4%) of the screened employees, while 222 (3.6%) had documentation of prior rubella vaccination or rubella infection. The absence of immunity was identified in 325 employees or 5.3% of all those screened. Logistical regression analysis demonstrated that five-year birth cohorts correlated significantly with serological status. Employees born in 1960-1964 were least likely to be seronegative, and employees born in 1970 or later were most likely to be seronegative. This study demonstrates a lower seronegativity rate than did previous studies. It identifies groups of employees likely to escape rubella screening and low vaccination rates. The increasing seronegativity among those born after 1964 correlates with increasing rates of rubella in the US.

Risk of exposure to blood among nursing personnel: Monitoring and evolution 1990-1992
Risque d'exposition au sang parmi le personnel infirmier - Surveillance et évolution 1990-1992 [in French]
This multicentre study (12 French health care centres), follow-up to a previous study (CIS 92-2055), covers the period from 1 Sep. 1991 to 1 Sep. 1992 to assess the changes in the incidence and the characteristics of blood exposure accidents (BEA). Participating teams were very active in developing preventive strategies suiting their needs. It is then incumbent upon employers to provide workers with the means to protect themselves with improved materials while taking into account other factors such as workload and organization. The resulting cost should be compared with that of serum monitoring, prophylaxis with AZT and with the social costs resulting from occupational HIV seroconversion or chronic hepatitis C. Appendices: list of participating centres in the 1990-92 study; questionnaire on the occurrence of BEA; main items of a survey conducted at the same time on BEA in operating theatres.

Morbidity, cost and role of health care worker transmission in an influenza outbreak in a tertiary care hospital
An influenza A outbreak involving 37% of health care workers and 47% of geriatric patients on a ward in a tertiary care hospital was reviewed. The majority of health-care workers became ill prior to detecting the first patient case of influenza, suggesting that nosocomial spread from staff to patients may have occurred. Only 13.7% of the staff and 5.9% of patients had been vaccinated prior to the outbreak. It is suggested that much of the morbidity and costs resulting from this outbreak could have been avoided by increased immunization of staff and patients.

Risk of human parvovirus B19 infections among school and hospital employees during endemic periods
Risk factors for human parvovirus B19 infections for hospital and school employees were identified during an endemic period. By serological testing, 2,730 employees of 135 schools in three school systems and 751 employees of a hospital were monitored. Of these, 60% were initially seropositive. After adjusting for age, race, and gender, risk factors for seropositivity were contact with children aged five to 18 years at home (odds ratio [OR]=1.2), at work (OR=1.2), and employment in elementary schools in school system 2 (OR=1.4). Over 42 months, one of 198 susceptible hospital employees seroconverted compared to 62 of 927 school employees. Four factors associated with seroconversion were employment at elementary schools in system 2, contact with children aged five to 11 years at home or with children aged five to 18 years at work, and aged under 30 years. Those in daily contact with school-age children had a five-fold increased occupational risk for B19 infection.

Risk of hepatitis A infection among workers of a large sewage plant operating association
Hepatitis-A-Infektionsrisiko bei den Mitarbeitern einer grossen Kläranlagenbetreibergenossenschaft [in German]
Antibodies against hepatitis A infection (anti-HAV) and anti-HAV-IgM were determined in 408 workers exposed to waste water in a sewage treatment plant and in 202 non-exposed workers. None of the workers were anti-HAV-IgM positive. In comparison with the control group, a significantly higher number of sewage plant workers were anti-HAV positive. For exposed workers over 40yrs old an odds ratio of 1.8 was obtained. Hepatitis A immunization is recommended for workers in sewage treatment plants.

Risk of hepatitis A infection in sewer maintenance and sewage purification plant workers
Hepatitis-A Infektionsrisiko bei Kanalunterhaltungs- und Kläranlagenarbeitern [in German]
Sanitation workers exposed to sewage were subjected to serological examinations to determine the presence of anti-HAV-IgG. All 15 sewer maintenance workers and all 27 employees of a sewage treatment plant of a German municipality were included. Sewer maintenance workers with more than five years of exposure were found to be HAV-positive while among the group with less than five years seniority, only one was HAV-positive. Of the employees of the sewage treatment plant, all with more than 11 years of exposure were HAV-positive and all those with less than five years seniority were HAV-negative.

Zoonoses transmitted by ticks (tick-borne encephalitis and Lyme borreliosis): Preliminary results
Le zoonosi trasmesse da zecche nei lavoratori forestali (tick-borne encephalitis e Lyme Borreliosis): Risultati preliminari [in Italian]
To investigate the diffusion of infections transmitted by ticks (Tick-borne encephalitis (TBE) and Lyme borreliosis) in forest workers, a serological investigation was carried out in the Province of Trento (Northern Italy) on the sera of 465 subjects at potential risk (foresters, hunters, woodcutters, gamekeepers). Antibodies for TBE virus were found in five subjects working in the same area, and antibodies for Borrelia burgdorferi were found in 15 subjects. All three clinical cases of TBE identified reported that they had been bitten by ticks in the same geographical area. The presence of specific antibodies for TBE virus was tested on the sera of animals grazing in several areas: four positive cases were observed in the same area as the human cases reported above.

Blood exposure and the risk of hepatitis B virus infection in firefighters
This survey assessed personal and occupational risk factors among uniformed fire department employees by a self-administered questionnaire and hepatitis B virus (HBV) infection status by serological testing. Overall, 46 of 592 employees had past or current HBV infection. Employees reporting blood contact with skin had been infected more often than employees without this exposure. Prevalence of infection did not differ by age, years on the job, or job duties. The adjusted prevalence of HBV infection among male employees was not significantly different from its prevalence in American men.

Exposure to blood-containing aerosols in the operating room - A preliminary study
A personal sampling study was conducted to assess exposure to blood aerosols in the operating room. The breathing zones of primary and assistant surgeons were monitored with a personal cascade impactor. "Hemastix" were used to assess the haemoglobin content of each particle size fraction. The mucous membrane lining of the upper respiratory tract and alveolar macrophages in the gas-exchange region are likely to be exposed to aerosolized blood in the operating room, as particles less than 3.5µm in diameter were found in 66% of the samples, and particles smaller than 0.52µm were found in 38%.

Seals, seal trainers, and mycobacterial infection
In 1986, three seals died in an Australian marine park; postmortem tissue culture suggested infection with Mycobacterium bovis. In 1988, a seal trainer employed at the park until 1985 developed pulmonary tuberculosis caused by M. bovis while working in a zoo 3,000km away. Culture characteristics, biochemical behaviour, sodium dodecyl sulfate polyacrylamide gel electrophoresis, and restriction endonuclease analysis suggested that the strains of M. bovis infecting the seals and trainer were identical but unique and differed from reference strains and local cattle strains of M. bovis. The infection in both the seals and trainer had a destructive but indolent course. This is the first time that M. bovis has been observed in seals and the first time that tuberculosis infection has been documented to be transmitted from seals to humans. Those working with seals and other marine animals should be monitored for infection.

Risk factors for lack of detectable antibody following hepatitis B vaccination of Minnesota health care workers
A total of 595 health care workers who had received hepatitis B vaccine underwent postvaccination testing for hepatitis B antibodies within 6 months of receiving the third dose of vaccine. Five variables were independently associated with a lack of antibodies: vaccine brand, smoking status, sex, age and body mass index. Results indicate that certain populations of health care workers are at increased risk of not responding to hepatitis B vaccination. Further studies evaluating the immunogenicity of currently available hepatitis B vaccines in persons at high risk for primary vaccine failure are needed.

Hepatitis B vaccine responsiveness in Connecticut public safety personnel
A survey was made of levels of hepatitis B antibody present among public safety personnel who had completed vaccination 1 to 6 months earlier. Of 258 individuals tested, 11.9% were found to have no or inadequate levels of antibody. The frequency of inadequate level of antibody increased significantly with age. Smoking, extreme obesity and increasing time interval since completing the vaccine series were also associated with inadequate levels of antibody. It is concluded that routine immunization of public safety personnel should include selective use of postvaccine testing.

Muco-cutaneous candidosis and occupational exposure to enzymes - A case report
Candidosi mucocutanea nella esposizione ad agenti biologici - Un caso clinico [in Italian]
Candida albicans, a common yeast in the environment, has properties allowing it to colonize and invade host tissues, often resisting eradication. Acid proteinase is the virulence factor. Bacterial proteinases are widely used in the detergent industry and the role of occupational exposure to enzymes in the development of muco-cutaneous candidosis warrants investigation. A case of candidosis is reported in a worker employed in a detergent factory in whom there was no evidence of any kind of immuno-suppression. The relationship between occupational exposure and illness is analyzed.
