Introduction: Exposure to Bioaerosols is related to a grand range of sanitation’s effects including intense poisoning effects, allergy and cancer. This study has done to determine the type and concentration Bioaerosols in the air of one of the industrial live stocks slaughterhouse in Shiraz.
.
Material and Method: A total of 112 air samples from different parts of industrial live stocks slaughterhouse are collected in this cross-sectional study. According to the NIOSH method, Bioaerosols sampling was done in blood agar medium and dextro agar and by Anderson one-stage sampler with flow rate of 28.3 Lit/min, sampling duration of 10 minutes and concentration measured in CFU/m3.
.
Result: According to the result, the most pollution is in blood cook place (3281.44 CFU/m3) and the least pollution exists in meat delivery place (99.1 CFU/m3 ). Also the result of the study showed that Bioaerosols concentration in industrial live stocks slaughterhouse is 28 times more than its concentration in reference site. Which is 5 km from slaughterhouse and 5 species of fungi were observe which aspergillus niger and penicillium were dominat.
.
Conclusion: Bioaerosols concentration in live stocks industrial slaughterhouse is higher than the threshold limit and suggested range. Therefore, it is essential to take measures, such as improving the process and technical-engineering interventions including the use of suitable ventilation systems and also management personal monitoring measures.
