Tilapia are one of the most common types of fish produced in Egypt, it represent 40% of total fish production, they easily farming and have an economic low price as well as their flesh are tasty and easy to cook (MegaPesca, 2001). Fish in large-scale production facilities are exposed to stress conditions, diseases, and deterioration and consequently spoilage of the final product resulted in a serious economic losses and/or public health hazards. Microorganisms are the major cause of spoilage of most seafood products (Gram & Dalgaard, 2002). Healthy fish possess bacteria on the external surface and the internal organs (Austin, 1983), consequently contamination in edible portions of tilapia could happen leading to fish spoilage and/or public health hazards (Al-Harbi & Uddin, 2005 and Herrera et al., 2006). During farming, tilapia is susceptible to the bacterial infection that considered a major cause of fish mortality leading to economic losses (Grisez and Ollevier, 1995). Sensory evaluation and total psychrotrophic counts are some indicators used for seafood quality determination under chilling storage (Paarup et al., 2002, Antoine et al., 2004 and Lopparelli et al., 2004). Probiotics are recently recognized as alternatives for antibiotics to control fish diseases and improve fish quality (Ahmed et al., 2007 and Aly et al., 2008).
