الملخص EN

This research was studied for the period between November 2012–February 2013.

which included compared the numbers and species of bacteria and fungi found in the air inside and around the slaughterhouse.

The results of statistical analysis show significant differences between the numbers of bacterial colonies isolate of air between inside and around the slaughterhouse during the months of study especially during the first month of the study and during the second month for the fungal colonies with no significant differences between the numbers of colonies isolate of air inside and outside the slaughterhouse.

Study proved that total numbers in the air was about 196 bacterial colony and 22 fungal colony for environment inside slaughterhouse and 266 bacterial colony and 43 fungal colony for environment around the slaughterhouse.

The results showed that eight types of a bacteria was isolated : staphylococcus aureus, formed highest appearance frequency (16.68 %) in both inside and around the slaughterhouse, E.coli (16.64 %), Streptococcus pyogenes (9.69 %), Bacillus subtilis (7.55 %), Salmonella enterica (3.83 %), Enterococcus faecalis(15 %), Klebsiella pneumoniae (14.09 %), Pseudomonas aeruginosa (16.34 %), and isolated and diagnosed five types of fungi from the air around the slaughterhouse which are : Aspergillus flavus, Asper.

niger, Mucor sp., Pencillium notatum, Pencillium sp., and four types of fungi inside slaughterhouse expect Asper.

niger, and was the highest appearance and frequency of the fungi in the inside and around Pencillium notatum (26.25 %).

This evidence of air pollution, the bacteria and fungi, have an important role both in spreading of diseases for humans and animals by the contamination of meat and in addition that are handled within the slaughterhouse and therefore dangerous to the health of the consumer to that air polluted in and around the slaughterhouse.
