title: Hazard analysis and critical point identification at Abiss slaughter house in Alexandria.
abstract: The purpose of this study is to identify potential hazards associated with animal slaughtering and how could these affect the microbiological count of carcasses, and to describe the use of HACCP to improve the microbiological count of fresh meat. Hazards were detected by observing the different steps of animal slaughter and then filling a prepared red meat slaughterhouse score sheet. The microbiological load was determined through testing 112 swab samples taken from the surface of carcasses in addition to 21 samples from hands, knives, tap water and air. Results showed that most of the parameters of the score sheet observed for evaluating hygienic operations were classified as being of maximum risk C. The aerobic plate count enterobacteriacea, mold and yeast and staphylococci increased insignificantly after cutting to 9.7x10(2), 6.4x10, 2.6x10(2), and 3.7x10 cfu/cm2, respectively. Washing of the carcasses decreased counts insignificantly to 6.4x10(2), 2.0x10, 1.7x10(2), and 2.0x10 cfu/cm2, respectively. The microbiological count of air samples at quiet hours were lower insignificantly than those at busy hours. Subsequently a HACCP system was designed based on these microbial studies, observations of current practices within the slaughterhouse and relevant literature and following the 7 principles of HACCP.
