Multiple sites of exposure in an outbreak of Ornithosis in workers at a poultry abattoir and farm.
Epidemiology and infection, 2007Co-Authors: Albert Tiong, Megan L Counahan, Jennie A. Leydon, Graham Tallis, Stephen B. LambertAbstract:Cases of Ornithosis amongst workers on a rural duck abattoir and farm were notified from late 2003 to health authorities in Victoria, Australia. In May 2004 we conducted a serological survey to identify the extent of exposure to Chlamydophila psittaci amongst workers and a case control study to identify high-risk work areas for Ornithosis-related pneumonia. Some workers in all occupational groups showed serological evidence of exposure, while those with pneumonia were more likely to have worked in the slaughtering area of the abattoir (adjusted odds ratio 16.7, 95% confidence interval 1.3-207). High exposure to blood and feathers from recently killed birds is likely to represent an occupational hazard to workers, but pneumonia did occur in workers without these exposures. We recommended respiratory protection for all abattoir workers and improvements to airflow and reduction of environmental contamination in high-risk work areas to prevent further cases.

risk exposures for human Ornithosis in a poultry processing plant modified by use of personal protective equipment an analytical outbreak study
Epidemiology and Infection, 2013Co-Authors: C J Williams, M Sillis, V Fearne, Lorenzo Pezzoli, G Beasley, S Bracebridge, Mark Reacher, P NairAbstract:Ornithosis outbreaks in poultry processing plants are well-described, but evidence for preventive measures is currently lacking. This study describes a case-control study into an outbreak of Ornithosis at a poultry processing plant in the East of England, identified following three employees being admitted to hospital. Workers at the affected plant were recruited via their employer, with exposures assessed using a self-completed questionnaire. Cases were ascertained using serological methods or direct antigen detection in sputum. 63/225 (28%) staff participated, with 10% of participants showing evidence of recent infection. Exposure to the killing/defeathering and automated evisceration areas, and contact with viscera or blood were the main risk factors for infection. Personal protective equipment (goggles and FFP3 masks) reduced the effect of exposure to risk areas and to self-contamination with potentially infectious material. Our study provides some evidence of effectiveness for respiratory protective equipment in poultry processing plants where there is a known and current risk of Ornithosis. Further studies are required to confirm this tentative finding, but in the meantime respiratory protective equipment is recommended as a precautionary measure in plants where outbreaks of Ornithosis occur.

The Prevalence and Regional Distribution of Antibodies against Chiamydia pneumoniae (Strain TWAR) in Finland in 1958
International journal of epidemiology, 1992Co-Authors: M Karvonen, Jaakko Tuomilehto, A Naukkarinen, Pekka SaikkuAbstract:The occurrence of nonavian 'Ornithosis' was reported in Scandinavia at the end of the 1950s. In order to find out whether Chlamydia pneumoniae had been present in Finland, we examined the IgG antibody prevalence to C pneumoniae in samples representing the whole rural population of Finland in 1958. The total number of sera studied using micro-immunofluorescence was 2000. Trend-surface analysis was used to examine the regional patterns of antibody prevalence. C pneumoniae antibodies were present throughout the country. The mean antibody prevalence was 56% among adults and 27% among children. Thus the possible role of C pneumoniae in nonavian 'Ornithosis' in Finland between 1958 and 1960 cannot be excluded.
