Microbiological Test of Chicken Liver Product in Baghdad Supermarkets

Easily metabolization of foods makes it suitable for accretion of microorganism. Many organisms could be growing in the liver due to its moisturizing media, nitrogenous compound enrichment and presence of growth factors. This study was conducted to investigate microbial contents of liver from Baghdad markets. Specific culture media were used to identify and isolate the bacterial organisms (nutrient agar, mannitol salt agar, salmonella shigella agar).One hundred samples from ten different chicken products companies were collected (ten for each company). Staphylococcus spp., Escherichia coli and Salmonella spp. represent the common pathogenic types which isolated in this study. 30% of those companies had mixed infection of all types of bacteria, 10% had an infection with two types, and there maining percentage (60%) showed single infection with Staphylococcus spp. This study also revealed that the liver was a polluted organ with pathogenic bacteria and the mean of infection was near the maximum standard limit. Therefore it is an important to improve the diagnostic and inspection techniques to identify the contaminated liver which sold in marketplaces.
