SALMONELLAS, POULTRY HOUSE ENVIRONMENTS AND FEEDS: A REVIEW

Abstract

The gram-negative bacteria and member of the family Enterobacteraceae is one of the most important causes of human food-borne illnesses in recent times. These pathogens may occur naturally in the gastrointestinal tract of poultry and sometimes in eggs through tram ovarian transmission. A number of factors have contributed to the spread of Salmonella in poultry. Among these are stocking densities of poultry farms, poultry feeds, farming activities, mice, wild animals, transportation of live birds to slaughter houses, slaughtering of live birds and processing of poultry carcasses into processed finished products. Lesser concerned area is the association between Salmonellas, poultry house environments and feeds and the significant role they may play to integrate other factors in contributing to the spread of Salmonella in.poultry. Furthermore, techniques for isolating and identifying Salmonella species in poultry house environments and feeds are crucial for reliable reporting purposes to reduce the spread of Salmonella by poultry thus the objective of this study.
