Microbial pollution of air inside slaughter houses

ABSTRACT

A total of 40 air samples were collected from 3 slaughter houses located at Giza [15], Damanhour [10] and Alexandria [15] and examined microbiologically. The average total bacterial count, coliform count and fecal Strept. count were 1400 +/- 306.4, 201 +/- 16.4, 140.02 +/- 32.1 and 84.3 +/- 19.2 bacteria/L, respectively. The isolated bacteria were Staph. aureus [15%], Strept. pyogenes [7.5%], Coryneb. pyogenes [2.5%], Coryneb. renale [7.5%], Coryneb. bovis [10%], E. coli I [37.5], Strept. bovis [17.5%], Strept. faecium [22.5%], Strept. durans [25%], Pseudomonas aeroginosa [20%], Prot. morganii [27.5%], Prot. mirabilis [32.5%], Prot. vulgaris [37.5%] and Arizona spp. [2.5%]. On the other h and, the isolated fungi were Aspergillus niger [15%], Aspergillus flavus [10%], Mucor spp. [20%], Penicillium spp. [25%], C and ida albicans [17.5%], Alternaria [15%], Rhizopus [22.5%] and Fusarium [12.5%]. The hygienic significance of each isolate was discussed
